RE: [flexcoders] Intellectual property or licensing of posted/blogged work

Since it was partially some of my code that kicked off this
discussion...
 
In general, almost everything published on my blog is published under
the MIT open source license, which was included earlier in this thread.
Very occasionally, I'll publish something that's not available for use.
I try and be explicit about it, but if you're looking to use something
from quietlyscheming and you can't find a license in the source, or a
description of the licensing on the page where I posted it, it's
probably best to just leave a comment or send me an email asking about
it.

I will now pass myself off as a legal expert despite the fact that I
haven't attended law school...so anyone with authority should overrule
my opinion.

Generally speaking, if the owner (which is usually the author) publishes
the code on the web, then you are allowed to look at it.  They showed it
to the public, the public gets to see it.  (It's the same theory that
while a billboard is still copyrighted, you can't tell people not to
look at it.)  You can even tell other people about it and where it is
(although you can't necessarily give them a copy yourself). 

As far as using it in your own projects, that depends entirely on the
license.  Sorry, there is no standard.  However, many blogs and most
adobe products/solutions/projects (including many you mentioned) are
pretty explicit on what you can do.  I assume if you publish things on
this list then you're ok with people using them as they see fit, but
that's a personal assumption, not a legal one.  Maybe there was
something in the signup that i missed which said this list is in the
public domain, but I don't remember it.

RE: [flexcoders] Re: Tutorial zoom in a linechart

[Ely Greenfield]

 
 
Hi Graham. That would work just fine.  It forces the chart to do some
extra work, b/c it still has to process those out of bounds data values
far enough to decide they're out of bounds.  So be alert for performance
issues. But other than that, it should work fine.
 
Ely.

I have a column chart with drill down functionality. When you click

more detailed chart is in a view stack with the drill down chart so
the main thing I do to get it to display is to change the selected
index of the view stack. 

The problem is that the columns have datatips and when I switch to the
new chart the datatip is still there. Any ideas on how to make it go

RE: [flexcoders] Accessing a Flex Model via JavaScript (FABridge)

[Ely Greenfield]

 
 
 
The FABridge relies on the ability to introspect actionscript types and
create proxies in javascript for classes, methods. and properties on the
fly. Since Model is dynamic it can't be introspected by the current
bridge behavior, so you can't manipulate it directly through the Bridge.
 
You have three options:
 
1) the bridge has low level APIs for setting and getting properties, and
calling methods, on an arbitrary object reference.  You can see if using
these to access members of the model fixes your problem.
 
2) if you know in advance what type of manipulations you want to do to
your model, you can write methods in your application to do them, and
call those (with parameters) from your javascript.
 
3) use a strongly typed class based model rather than the generic model
tag.

RE: [flexcoders] Re: Adding annotationElements programatically

[Ely Greenfield]

 
 
Rule of thumb in actionscript...there's no way to detect a change in an
array. So if you're calling 'push' on an array and expecting some other
component to notice, you're going to be unhappy. You need to explicitly
inform other components that the array has changed, usually by just
passing it the array as a 'new value.' 
 
In this case, there's some small cost to reprocessing the other
annotation elements, but nothing too heavy.
 
Ely.

I am also trying to add annotationElements programatically and have a

My annotationElement uses its dataTransform object to convert data

annotationElements in MXML it works fine. However when I try to add 
it programatically in Actionscript (as below) the annotationElement 
is instantiated but its dataTranform remains null.

Am I missing something? Is there an extra step required to set up 
the annotationElement's dataTransform object?

Hi guys,

We have a chart displayed on a dashboard amongst other components, when
a user selects a different chart we need to remove the chart and display
a different one, I was going to use view states but we have lots of
different charts and it "seems" that the charts not in the current view
are still "alive" and respond to events they are subscribed for, is this
correct ?

In "flash" i'd remove the movie clip and load a new one, can I remove
the component and load another one within my dashboard ?

RE: [flexcoders] Please Help with CandleStick Chart

[Ely Greenfield]

 
 
I'm assuming by looking at your data that you have multiple series in
this chart, and you're trying to figure out which series they clicked
on?
 
The ChartItem has a property called element which points back to the
series it's associated with. You can use that to decide whether it's
open1, open2, etc.

Subject: [flexcoders] Please Help with CandleStick Chart



Hello,
I have a problem which I am sure is easy to solve but I am missing a 
piece of the pazzle.

I have a CandleStickChart.

In my candle stick chart I have an underline array collection.

My array collection looks like this:

[Bindable]
private var expensesAC:ArrayCollection = new ArrayCollection( [
{ Date: "25-Jul", Open1: 40, High1: 40, Low1: 20, Close1:20 , Open2: 
42, High2: 42, Low2: 48, Close2:48 , Open3: 60, High3: 60, Low3: 
50, Close3:50} ]);

As you can see, I have a single column which is broken into multiple 
Open/Close High/Low + an index number ( 1 - 10 )

I have an event so whenever an item is clicked on the chart I grab it 
such as:

private function selectBox(event:ChartItemEvent):void { 


trace("A TimeClockID: " + 
event.hitData.item.Open1);
trace("B TimeClockID: " + 
event.hitData.chartItem.index); 

trace("C TimeClockID: " + 
event.hitData.chartItem.itemRenderer.name); 

trace("D TimeClockID: " + event.hitSet.valueOf
());
trace("D TimeClockID: " + event.hitSet);



}

The problem is that I can not find away to figure out which specific 
column in the candle stick chart the user clicked on.

In other words, if you look at:

trace("A TimeClockID: " + event.hitData.item.Open1);

I get the valid data which Open1 holds.

However, I do not know if the user clicked on Open1 or Open2 or Open3.

I just know which object in the chart he clicked on, but I DO NOT 
KNOW which object he clicked on within the object ( i.e.: did he 
click on Open1 or 2 ... 3 ... ) .

How can I figure this out ...

Help

Sean.

RE: [flexcoders] Negative plane in Column Chart

I'm not understanding your question.

RE: [flexcoders] Chart Series - formatDataTip inconsistent visibility

[Ely Greenfield]

 
 
In general, they're prive because we provide an alternate method for
changing the datatip that doesn't require subclassing (setting the
dataTipFunction on the chart).
 
Depending on the scenario, it feels a little bit like overkill. If I
were writing this myself, I would write my own dataTipFunction for the
chart, which just cased on the type of the series generating the
datatip, and took appropriate action. The only reason I would bother
with subclassing the series is if I were trying to wrap up new or
modified series types for use in other apps or by other developers.  
 
If you really want to keep the datatip functionality encapsulated in the
series...The way datatips work is that the series stuffs a reference to
its datatip function into the HitData structure before it returns it
from the findDataPoints() function.  So I would subclass the series,
override findDataPoints, call the super() version, and then right before
returning the hitData structures generated by the super version, stuff
my own altenrate data tip function into the hitData structures.

I started making some application specific tweaks to the chart series
dataTips, and it worked beautifully for ColumnSet (override the
protected function formatDataTip), but then I soon realized that only
the SET series (subclasses of StackedSeries) have that function as
protected. It's actually private on all the standard series.

Is there a reason that it's private on the normal series, but
protected on the series sets?

I am thinking as a workaround, I'll have to do something like this.
what do you think?

Use the chart's dataTipFunction, and call back into the series (via
hitData.element) to a slightly differently named function
(myFormatDataTip) defined on the series subclass. I don't like this
because then I have to make sure the myFormatDataTip function exists
before calling it, and I make assumption about the signature, but I
think that would work...

comments?
thanks,
PW



 

RE: [flexcoders] Re: Chart Series - formatDataTip inconsistent visibility

[Ely Greenfield]

 
 
In this scenario, I would suggest subclassing the Stacked series
(ColumnSet, or whichever you need), and exposing the percent values.
i.e., add a get function that looks something like:
 
public function
getTotalsValuesBecauseElyWasStupidAndMadeThemProtected():Array
{
  return stackTotals;
}
 
then do the rest of it from external datatip functions.  We'll make the
stackTotals publicly accessible in the next release.
 
Regarding the general question of public/protected/private:  Writing
frameworks is a tricky business. Every public or protected method gets
locked in stone, restricting our ability to innovate with each
release...i.e., if the behavior is defined, accessible, overridable,
then it ties our hands in our ability to refactor code and functionality
because someone might be relying on it. Given that we're trying to do
our best about maintaining compatibility in future releases,   We have
to be very careful about what we make public.  Clearly we have got some
of them wrong (and will continue to), and we want to hear what those are
so we can fix them. But erring to far on the other side...making
everything public...probably would be the wrong answer for everyone.
 
Ely.

Ely,

Thanks for the info.

The reason I was going with subclasses, is because the Stacked type
series stacking information (stackTotals) is protected, so I needed a
subclass.

This whole thing started with the Stacked type series, the simple
series could possibly be handled in a single case statement. However,
since I have to use a subclass/override dataTipFunction for that, I am
kinda stuck going the subclass route right? Is there some way to do
the chart dataTipFunction and also in some cases use the series
supplied function?

In general, It seems like I find a lot of cases where it seems
completely unnecessary to make a function or variable protected or
private. I mean in the case of formatDataTip, that function does not
modify anything, simply formats a string. That could have been public
even. no danger of calling, and useful for calling or overriding.

If it were public, it would be easy to use the case statement, supply
the default formatDataTip function in the default case, and override
just the ones I wanted to. And if I could have gotten to the stack
totals that would have been just as good or even better.

thanks,
PW

RE: [flexcoders] Zooming out of a list ?!

[Ely Greenfield]

 
 
Hi Jamie. That's pretty much exactly how I would reccomend doing it.  
 
as for #2:  all displayobjects have a property called localToGlobal(),
which converts coordinates from the component's coordinate system to the
global coordinate system.  So you could do:
 
 
var topLeft:Point =
systemManager.globalToLocal(myItemRenderer.localToGlobal(new
Point(0,0)));
var bottomRight:Point =
systemManager.globalToLocal(myItemRenderer.localToGlobal(new
Point(myItemRenderer.width,myItemRenderer.height)));
 
and there you've got the bounding box for your component in
popup-coordinate-space.

Subject: [flexcoders] Zooming out of a list ?!



Hi,

I've been exploring the wonderful world of effects and transitions 
recently... there's something I would *love* to be able to do - but 
I suspect this is not possible. Could someone confirm or deny 
accordingly ?!

Here's the idea...

I have a horizontal list which consists of a set of charts. This 
list is quite small - acting really, like a row of thumbnails for 
the charts.

If the user clicks on a chart, it appears in a nice big readable 
size in a popup window.

Now... what I'd like to do is apply a 'zoom' style transition from 
the clicked list element to the popup window so that the popup 
appears to zoom out of the list itself.

Actually, as I write this, a *possible* solution has occurred to 
me...

(1) The user clicks on an element on the list
(2) This causes a totall borderless popup window to be created, 
exactly over the chart in the list that the user clicked on. This 
would appear 'invisble' to the user since visually it should look 
the same.
(3) A sequence (consisting of a zoom effect and move) is applied to 
the popup to expand it and bring it into the centre of the screen.

If this is possible, I *think* it would look ok ?

Question then is, how to achieve (2)...

Or am I barking up the wrong tree ?!

Jamie.

RE: [flexcoders] CurrencyFormatter applied to LineSeries

[Ely Greenfield]

 
 
Marc -- what exactly are you trying to do?  Format the labels on the
axis?  On the datatips? elsewhere? For the chart to work, it needs to be
able to run calculations on the y values -- pre-formatting them prevents
that.  If you're looking to format datatips, try a data tip function on
the chart.  If you're looking to format the axis, try a label function
on the vertical axis.

RE: [flexcoders] Chart annotationElements based on series data

There's no obvious way to do what you're doing.  The annotation element
has access to the chart, so you could iterate over the series of the
chart, and ask for their data. To get access to what is currently
visible on screen, you could ask for their renderData, then look at the
filteredCache inside of that.  Of course, now you're tying your
annotation element pretty tightly to the details and implementation of
the individual series.

RE: [flexcoders] How to align identical CategoryAxis as HorizontalAxis and SecondHorizontalAxis

[Ely Greenfield]

 
 
Are you trying to align the gridlines, or align the axes?
 
The short answer is no.  There's no general way to force the chart to
align a horizontal and secondary horizontal axis (with the asumption,
perhaps wrong, being that the reason you're using secodary axes in the
first place is because the data is unrelated).  If you have the same
number of values in the horizontal and second horizontal axes, you could
explicitly set the gutterLeft and gutterRight on the chart, which would
make the two axes line up, at the expense of some auto-layout
functionality.

the interval differently than the bottom axis. The gridlines are

RE: [flexcoders] How to align chart items in two charts?

[Ely Greenfield]

 
 
by default charts compute their gutterLeft and gutterRight dynamically,
but if you need to get two charts to align, you can set them to explicit
values. You lose a little bit of flexibility in axis/label layout...it
will fit the axes to the space available rather than choosing the best
space available for the labels, but if you choose appropriate values it
should work fine.

Re: [flexcoders] small problem with Bar Chart showing days

[Ely Greenfield]

I don't think there's any way to do this theokgh configuration alone. But you 
could override the bar series update function to always layout an item with a 
min width. Easier would be to provide a custom item renderer that, below some 
minimum width, ignored what the chart was telling it and adjusted its own 
rendering size and location accordingly. 

(note that I wouldn't bother having your renderer mess with its actual x y 
width height- just adjust how it actually renders itself.)

I'm using a bar chart to show the start and end of a product roll-out. 
I'm using the xField as the start date and the minField as the end 
date, it works and looks real nice. The one problem I've run into 
though is the product(s) that roll out in one day. So if the start 
and end dates are the same I don't get a rendering of a bar... not 
even a little.

Does anyone one have any advice on how to force those bars to render? 
Maybe there's a way to set a min width to it that I can't find? Or 
maybe someone else has run into this kind of thing?

RE: [flexcoders] Chart Axis Labels as Link

[Ely Greenfield]

 
 
Brian -- are your labels set at an angle?  If they are, it would explain
why you are having problems.  The Flash Player can't render device text
at an angle. You'll have to use embedded fonts, or set the axis to not
render the labels at an angle.
 
Regarding the performance...Are you seeing actual performance issues, or
just lots of updateDisplayList calls?  It's hard to tell without more
information, but it's totally reasonable to expect that your labels will
be rendering alot. Every time anything in the chart changes, it needs to
verify that its displaying the right ranges, the right labels, in the
right location.  All of that would require updating every one of your
labels.
 
But it's also possible that something you're doing is causing excessive
updates. It's also possible that custom label renderers don't perform
well ;)
 
Ely.

I've searched the list and can't find anything quite touching on this
issue. I have a bar chart (with custom item renderer) with two
vertical Category axes and a horizontal Linear axis. For each of the
Category axes I'd like the label to be a link to an URL. I can get the
*text* as I want it using labelFunction on the mx:AxisRenderer without
trouble but I'm baffled as to how I'd get the label to be a link. I'm
guessing I need to write a custom label renderer (or two) but I just
can't get it to work. The LabelRenderer I created (extends UIComponent
implements IDataRenderer) performs horribly -- updateDisplayList is
called constantly according to trace statements -- and displays no
label.

Could anyone at least verify that it's possible to have a web link as
an axis label and that I'm heading down the right path creating a
label renderer? If so, any pointers on how to get the label to be a
link?

Subject: [flexcoders] Charts - Rotated labels not visible on horizontal
axis



Hi there,

I am trying to use labelRotation (45) on a Horizontal Axis but it 
does not work.
Background:
I get data for the charts through an HTTPService, so there is a few 
seconds lag between the graph (the axis & legend etc.) appearing and 
it getting populated with data. My horizontal axis is a datetime 
axis.

I see the following strange behavior.
When the graph appears without any data, the horizontal axis label 
is rotated to 45. At this time there is just one label at the right 
end point of the axis "2 jan 1970". I assume this is some default 
value which Flex is assuming. But when I do get the data and the 
chart gets drawn, the labels are no longer visible(!!!) and also the 
formatting that I had done on the horizontal axis is lost. The 
standard formatting with the thick gray line takes effect. The 
expected output would be to see all the labels rotated to an angle 
of 45.

Can someone help me to understand why this is happening and set this 
right?

Thanks
Deepa.

RE: [flexcoders] custom charting component question

[Ely Greenfield]

 
 
Brendan -- and anyone else implementing drag functionality --
 
  as a general rule, the way you should implement drag functionality is:
 
- add a mousedown handler to the thing you want to drag.
   - on mouse down, add a mouse move and mouse listener handler _to the
systemManager_, _in the capture phase_.
   - on mouse move, update your data.  Keep in mind that the mouse event
x/y for mouse move will be in systemManager coordinates, so either use
mouseX/mouseY off of the original target, or convert all coordinates to
global before doing any computations.
  - on mouse up, remove your move/up handlers _from the system manager_
during _capture phase_.
 
That will fix the problem with your current example where the drag
breaks when you move the mouse too quickly.

Subject: [flexcoders] Re: Charts - Rotated labels not visible on horizontal axis

Hi Ely & all, 

I think I got it working. I am actually dealing with a lot of data 
i.e. day-wise data for 3 years (365 * 3 records). We use this to 
draw our chart.

I was initially setting autoAdjust=true on the DateTimeAxis hoping 
that Flex would decide how many labels to display based on available 
space. But the labels werent visible & hotizontal axis was losing 
formatting.

To solve this, I set autoAdjust="false" and gave my custom 
interval=100. The labels appear now.

Thanks
Deepa.

Re: [flexcoders] How to switch a single axis chart to a dual axis chart ?

[Ely Greenfield]

Series draw against their asigned axes regardless of whether or not their 
axisrenders are visible. You need to switch the second series to be the primary 
series.

Hi there, 

Is it possible to change a single axis chart to a dual axis chart and 
vice versa?

Upon checking a check-box, I tried making the 
secondAxisRenderer.visible to true or false, but this does not redraw 
the second series against the first axis, it just hides the second 
axis.

Does anyone how I can do this?

Hi, group,
When I was playing with BarChart, I noticed that the entire bar 
will disappear when its height exceeds the range of the 
corresponding axis (e.g, do a zooming). Is it a designed behavior? 
Can I keep a bar shown on the plot even when part of it exceeds the 
range?

I attached below an example modified from BarChart document to 
demostrate this issue. When click "zoomin", you will notice that the 
tallest bar will disappear)

Yeah, the problem is that the Canvas container only allows children that
implement IUIComponent. It would have been real nice if Adobe had
provided a "raw" container that did no layout of its children (but
implemented IUIComponent itself), but they didn't. 

Fortunately, Grant Skinner has provided just such a container...
DisplayObjectWrapper. Check out his blog or Google for it.

If you wrap your Bitmap with the DisplayObjectWrapper first you'll then
be able to add it (or rather, the DisplayObjectWrapper) to the canvas.

Hi guys, 

Is following possible : 
Let's say I have a columnChart with two columns. One with value 700 and 
one with value 800. Now, the x-axis is value 0 (projected on y-axis), 
and the columns are 700 and 800 high. Now I would like to have the x-
axis represent 600 (projected on y-axis), so it would seem you have one 
column of 200 and one of 100. The labels on the y-axis need to start at 
600 (where it used to be 0).

OK, I got the size working, but now I have a new problem. I used a 
custom itemRenderer to change the size if the dates are the same. 
The code is redrawing the bars with a fill color of red (for now). 
I want that solid color to be a gradientFill, but I can't seem to 
get it to work at all. When I use the "beginGradientFill" like the 
code below all I get is 2 colors without an actual gradiant between 
them (and I'm trying for four colors). I tried using the Matrix but 
that just confused me more. 

Can someone lend a hand with that part?

Here's what I have with the solid color --

package
{

import flash.display.Graphics;
import flash.geom.Rectangle;
import mx.charts.ChartItem;
import mx.core.IDataRenderer;
import mx.core.UIComponent;

public function get data():Object {

}
public function set data(value:Object):void {

return;
//

return;
_chartItem = ChartItem(value);
}
override protected function updateDisplayList
(unscaledWidth:Number,unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth, unscaledHeight);
var rc:Rectangle = new Rectangle(0, 0, width , height );
var columnColor:uint;
var g:Graphics = graphics;
//
//
g.clear();
g.moveTo(rc.left,rc.top);
// Only if the _chartItem has data 
if (_chartItem == null) 
return;

It is interesting that I would get 4 replies, 4 completely different
answers. My entire week is going this way. As is my Flex project.
So my choices were:

1. Try the Grant Skinner blog and his DisplayObjectWrapper. Not
exactly sure how this works or how to use it within my code. 
2. Add .clone to my existing syntax, which I tried without luck
3. Have an image load an image and then copy that - interesting, yet I
have a canvas loaded with many bitmaps and need to make a bitmap of
the canvas ??
4. And finally, from Ely, and extension of the UIComponent class. I'm
sure this is something, but I'm not sure how to use it. 

I really appreciate the helpful spirit on this message board. My own
green-ness with Flex is part of the problem, but I thought for sure my
original direction would work since I pulled it almost directly from
the Flex docs. 

Here's the code from Flex Docs:

import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.text.TextField;

var tf:TextField = new TextField();
tf.text = "bitmap text";

var myBitmapData:BitmapData = new BitmapData(80, 20);
myBitmapData.draw(tf);
var bmp:Bitmap = new Bitmap(myBitmapData);
this.addChild(bmp);

They are copying a TextField rather than a canvas. Is that the issue? 
OK to turn a TextField into a bitmap, but not a canvas?

Just as a coding suggestion...you can put expressions inside [] array
initializers. So instead of this:
 
var g1:GradientEntry = new GradientEntry
(0xFF9900, 0, 1);
var g2:GradientEntry = new GradientEntry
(0xFFCC00, .20, 1);
var g3:GradientEntry = new GradientEntry
(0xA35901, .50, 1);
var g4:GradientEntry = new GradientEntry
(0x2B1500, .85, 1);
var g5:GradientEntry = new GradientEntry
(0xFFCC00, .95, 1);
fill.entries=[g1, g2, g3, g4, g5];

 
You can do this:
 
fill.entries = [
new GradientEntry(0xFF9900, 0, 1),
new GradientEntry(0xFFCC00, .20, 1),
new GradientEntry(0xA35901, .50, 1),
etc.

Hello Flex Coders!!

I have just joined the group as I've got stuck on this Flex charting
problem. 

I need to plot a line that ends with a wedge shaped area - looking
like a broom on its side, brush to the right, and then plot some
dashed lines across the same chart.

The minField property doesnt seem to work on a DateTimeAxis (requires
a category) so that was no good.

Using a stacked area chart did work and by setting the series I wanted
to appear as a just a line with an area but no fill and then setting
the y axis minimum to >0 so the line didnt plot from the last non zero
data point to the x axis worked OK (its an interesting feature that
lines are only rendered when both ends are within the xy ordinates of
the axes).

But then when I tried to add a non stacked line the compiler could not
resolve the stacked and unstacked series together. I tried defining
them as a secondseries group tag on a 2y axis as well. No joy.

On looking into stacking classes these are all topped with warnings
that they are not for normal use.

Anyone got a good idea on how to get my lines plotting unstacked but
over the top of some stacked areas?

Thanks

Mike



 

RE: [flexcoders] Re: Labelling the bubbles of a bubble chart

[Ely Greenfield]

 
 
 
Well...you'll have to look at BubbleSeries.as.  The three bits of
functionality you'd have to add are:
 
1) label management.  you'd want to create one label for every item.
The series do that with renderers by using a class called InstanceCache.
You'd probably just want to create another instanceCache that generates
Labels (or UITextFields, if you want to go low level).  All the series
allocate their renderer instances in udpateDisplayList
 
2) size reporting.  Series report how much space they need in the axis
ranges (when axes are generating axes automatically) in their
describeData method.  In that method, a series can describe a) what data
values need to be displayed, and b) how much space (in pixels) is needed
around those data values. You'll need to measure the sizes of your
labels, and make sure the chart allows for enough space around each data
point to make sure the labels are visible.
 
3) positioning.  In your updateDisplayLIst, that's where you'll actually
position each label.
 
 
Ely.

Hi,

I haven't seen this question anywhere yet, so hopefully I can get some
help here.  

I know the gutters for a chart are computed if they aren't explicitly
set.  We are showing 8 small line charts in a tile list (2 rows of 4).
Because the data shown can have values anywhere from 0 to well over
100,000, I don't know what the correct size for the gutter should be.
I'd like to let Flex automatically calculate the gutters for me, but the
font is sometimes scaled too small for it to be readable.  Any ideas on
how to overcome this?  I'd prefer to specify a minimum width and let it
grow if necessary.  I'd rather not specify the leftGutter because then
there can be too much white space left over.

Since your linechart is inside a repeater, the member referenced by its

There's no built in support for doing this.  If I were to try and make
this happen, I would probably do it like so:

 

1)  The PieSeries has a property called labelContainer.  This is a
reference to the flash.display.Sprite that contains all of the labels
being displayed by the Series.

2)  I would, early in initialization, grab a reference to this
Sprite.  Add an event listener to the sprite that will get called
whenever a child is added to the sprite.

3)  Whenever a child gets added, add a click handler to the child.

4)  When your click handler gets called, grab the text of the
currentTarget of the event. Use this to determine which item in the
dataProvider the label refers to.

RE: [flexcoders] Re: Filtered data in Plot Series

[Ely Greenfield]

 

 

 

Paul - 

 

Item renderers, in the chart (as elsewhere in the framework), get
recycled. Which means that the same item renderer may get assigned
different data items at different times.

 

My bet as to what's happening here is:  in your custom item
renderer.data property, you're not calling invalidateDisplayLIst(). The
first time your renderer gets data, it displays correctly, because it's
never been updated so it will go through an initial update pass. But
when its data property is assigned to a different value, it doesn't
automatically get updated unless you explicitly say that you need
updating, so you never see the rendering change on screen.

 

The datatip is working correctly because you actually update the data
tip in your set data function.

 

That's my first guess at the problem. If that doesn't solve it, we'll
have to dig deeper.

 

Ely.

I've tried to simplify this test case a bit. It involves "scrolling" 
of the data. I'm modifying the min & max values for the 
DateTimeAxis. 

You can view my "simplified" example @ 

http://programming.wrighthomeenterprises.com/Flex/Chart.html

The source is also available via the standard View Source mechanism.

You'll observe two PlotSeries with the same data provider, etc...
The only difference is in the value of the filterData attribute on 
the PlotSeries. 

As you scroll left to 10/8 & 10/9 entries, you'll see the disparity.
The interesting part is that the tool tips for each of the plot items 
is correct in both cases.

This may simply be a result of my limited experience in writing a 
custom item renderer here. I couldn't find an easier way to do this.

If you see a glaring error in my custom item renderer implementation, 
I would be grateful regarding any revelation. Thanks in advance for 
any assistance with this problem!

RE: [flexcoders] datetimeaxis problem

[Ely Greenfield]

 

 

 

Unfortunately, the current public DateTimeAxis doesn't support this.
Your options are:

 

1)  Use a category axis.

2)  2) write your own custom axis.

 

We're looking at including this functionality in a future release of
Flex charting.

Mikhail --

Flex 2 only supports 2 axis renderers.  The underlying architecture
supports arbitrary number of independent axes, but you'll have to get
pretty deep into writing a custom chart to get access to the
functionality.  This is a feature we're considering for a future
charting release.

Err, yes ?
So scale them (client or server-side). It's only math and a for loop.

RE: [flexcoders] DateTimeAxis problem: aligning dates with their year value

[Ely Greenfield]

 

 

Peter...usually that's a problem of time zones. i.e., you're specifying
your times in local time, and the DateTimeAxis is rendering in UTC.  So
Jan 1 in local time becomes Dec 31 in UTC, for example.

Subject: [flexcoders] DateTimeAxis problem: aligning dates with their
year value

 

Experiencing an interesting problem with the DateTimeAxis. Below is
the full code for a very simple LineChart app that's charting one data
value across a DateTimeAxis (this a small variation of the
DateTimeAxis example from livedocs). The date values for the
DateTimeAxis are String values in a local ArrayCollection in the
accepted "MM/DD/" format.

The problem is, all of the dates are getting charted one month too
soon. This is especially apparent in this example, where all of the
dates are on January 1st of each year: the data points are clearly
lagging behind the year points on the x-axis (I added a verticalStroke
here to show the discrepancy more clearly). If I change all of the
data points to February-1st, they all get incorrectly drawn exactlty
on the year-line.

Any suggestions are appreciated!

Charts don't support stacking negative values.  If you need this

RE: [flexcoders] Question on Ely's SuperImage Component

[Ely Greenfield]

 

 

Hi Mike. There is a _content property in the SuperImage, which is
essentially the same as the Image.content property. However, the
SuperImage actively maintains the size and position of the content, so I
don't think you can guarantee that changes you make to its position will
stick.  

 

So, two options:

 

1)  Grab the source, and make the modifications you need. An
'offset' might be a nice property to add, and something we could
integrate back into the main source.

2)  Wrap the Super Image in a Canvas. And move the SUperImage around
inside the canvas instead.

 

Ely.

Subject: [flexcoders] Question on Ely's SuperImage Component

 

Hello All,

I know there are lots of people using this, so I wanted to ask if this
component can perform some functions that the standard Image Component
can do.

With the standard Flex Image Component, I can move the Content around
inside the container, independent of the container itself. I do this
quite often, if I have an Image that is quite large - and has a lot of
extraneous background stuff that I don't want to be displayed.

With the Flex Image, I size & place the container where I need it to be
- then I move & scale the Content around within the container - in order
to show only the parts that I want.

The SuperImage Component doesn't have a Content Property - so this leads
me to believe, that I can't perform the same functions as the Image.

Is this the right assumption to make? If so, does anybody have any
further ideas, on how I can get more control over the content when using
the SuperImage?

Thanks in advance, for any information offered on this topic.

Problem:
I would like to display chart datatip from a set of datapoint

It seems that I have to overwrite the findDataPoints method
from ChartBase and returns an array of HitData points.

I can not figure out how to create a HitData object
from a specific datapoint regardless of the position of the mouse.

Maybe a new method such as showDataTip on chartBase taking as parameter
an array of indexes defining the datapoint from the dataprovider 
object could be helpfull.

RE: [flexcoders] LinearAxis - need help with value ordering! (Repost with sample code)

The kludgey answer  is:

 

1)  Invert all your values (5 becomes -5)

2)  Add labelFunctions to your axis (and possibly dataTip functions)
to re-invert the values before they get displayed on screen.

 

There's no functionality in the charts right now to just tell an axis to
render top to bottom.

RE: [flexcoders] Re: Image Component Nightmare

[Ely Greenfield]

 

 

My guess is that you have an explicit width / height set on the image.
In flex, an explicitly set width height Is essentially setting the
widthAfterScale and heightAfterScale.  So setting scaleX and scaleY
won't change the on screen rendererd size of the child. You need to
manually scale the explicit width/height, _and_ set the scaleX/scaleY of
the image.

 

Ely.

Thanks for your replay. Had a look on it, maybe will take another one,
but as I was trying to do the same with a Loader component, issues
were the same. Event.INIT event is fired by the Loader and it's width
and height remain 0, and I have to use loader.content too. That's just
something I don't get. Why do width and height remain 0 after an INIT
event?

RE: [flexcoders] Absolutely forcing chart to redraw

[Ely Greenfield]

 

 

 

Carl - 

 

Can you share some sample code? The simpler the better.

 

 

My short answer is...the chart will only set the data property on your
renderer if the chart knows things have changed. Since the chart knows
nothing about the size or color fields, it won't trigger an update.
You'll need to have your dataprovider items dispatch change events, and
have your renderers listen to the data object (the item) for those
change events yourself.

 

Or, re-assign the dataProvider to the chart, to slam a full update.

 

Ely.

Subject: [flexcoders] Absolutely forcing chart to redraw

 

I asked this earlier and didn't get any response... but I think maybe
I hijacked another thread, so I'll ask again as it's own topic.

I have a PlotChart that uses a custom itemRenderer. The dataProvider
bound to the chart has objects with the keys:
- xAxis:Number, which translates to the position on the xAxis of
the chart (-10 to 10), as the value moves to negative, the items color
changes from green to orange to red
- yAxis:Number, which translates to the position on the yAxis of
the chart (-10 to 10), as the value moves to negative, the items color
changes from green to orange to red
- size:Number, which translates to the size of the item (diameter
of circle)
- visible:Boolean, which determines whether the item is actually
plotted on the chart or not

At runtime, the chart initially loads exactly as expected (items the
correct size, color and position). Then if I update the values for
xAxis and/or yAxis, the item moves on the chart as expected (though if
it moves from a positive value to negative value on either axis, the
color remains green). 
But if I update the value for size it doesn't update the item on the
chart, and if I update visible to false the item remains visible.

Obviously the data setter function in my itemRenderer class is not
called when I expect.

Also, if I completely replace the dataProvider with a new object, item
1 retains the color and size of item 1 in the old data, and so on.

I've tried explicitly calling invalidateDisplayList() and
validateNow() on the chart, but it seems to just run the
updateDisplayList(). This makes some sense... I guess set data is only
run when the chart is first initialized. Seems like I really want the
bulk of the logic that's currently in the data setter to be in the
updateDisplayList() function... but I don't seem to have access to the
dataProvider data in that function.

How do I force the chart to rerun the renderer for the item(s) with
updated data? Or, conversely, how do I get at dataProvider values from
the updateDisplayList() function in the class?

Any help would be appreciated.

Thanks in advance!

Hi Carl. I'd like to help, but I really need to see your code.  Again, a
very simple example...of your item renderer, and the mxml, and some
actionscript that shows what kind of a change you're trying to
make...will be necessary to really help.  I don't see your item renderer
code in the post below.

RE: [flexcoders] How to assign chart series itemRenderer in AS3?

[Ely Greenfield]

 

 

Good question.  You could think of it as a subtle but important
difference...for lists, the item renderer is often very specific to the
type of data being rendered.  For charts, it is sometime very specific
to the data schema, but just as often, purely a stylistic choice...do
you want round points on your line, or diamonds?  More importantly, do
you want round points on the first line, diamond points on the second
line, etc?  As a stylistic (and per-instance) option, we wanted people
to be able to develop style based themes for charts that just 'drop'
into place.  

 

Or, if you were less charitable, you could claim it's just a mistake on
our part, and itemRenderer should be a style everywhere J

RE: [flexcoders] Re: looking for a SeriesSlide that keeps the old points on the graph

I don't  believe that would be possible with the current chart effect
API.  That would require the series to create a superset of the before
and after items to display at the same time. The effects generally don't
have the ability to ask the series to create or show more items, and
they don't know how to create or show more themselves (which would
require deep knowledge of the individual series).  It's a good

I should add...the interpolation effects do this, but they cheat. Each
series has specific support for interpolation built in to them, and the
interpolation effect just calls to the series to set up and execute the
interpolation.

RE: [flexcoders] Re: looking for a SeriesSlide that keeps the old points on the graph

[Ely Greenfield]

 

 

 

Glad to hear it J

 

You could definitely try...

 

1)  Fixing the min/max of the horizontal axis

2)  Add new items off the edge of the chart.

3)  Turn off filtering on your series

4)  Animate the min/max of the axis

5)  Remove the previous items.

 

Not sure how it would perform though.

Thanks for the clarification, Ely.  Probably saved me some time dinking
with effects.  I was afraid this might be the case.  So I'm guessing the
best thing to do is to turn off effects and intelligently remove/add
data points. 

BTW, I'm using your DrillDown/Up effects and just love them.  Your blog

RE: [flexcoders] ChartBase.invalidateData()

Hi Jason. Probably not a great reason why it shouldn't be exposed, other
than it wasn't designed to be.  i.e., log a bug, enhancement request,
etc. because I think it's a good idea. In the meantime, if you want, you
could subclass your chart type, and define a method:

 

Public function publicInvalidateDataBecauseElyIsStupid():void

{

This.invalidateData();

}

 

But since invalidateData wasn't designed to be a publicly visible
method, no guarantees on what bad effects this will have. None that I
can think of, just keep your cat away from the computer the first time
you run it J

I'm working on code to add one data point at a time to the chart.  I'm

I know there's ways around it, like reassigning the dataprovider or

RE: [flexcoders] Re: Absolutely forcing chart to redraw

[Ely Greenfield]

 

 

 

My guess would be that you've got a performance gate at the top of your
set data(...) function.  If the item renderer is being a passed a
reference to an item it already knows about, your set data(...) function
bails out. Which means that the code immediate below...which loads all
of the data out of the item into cached fields...never gets run. So if
the dataprovider hasn't changed, but the individual items have,
generally your item renderer won't update its cached  values.

 

Remove that line, and it might solve your problems?

grasping at straws, have you tried a bubble chart instead? I suspect
the series are derived from the same root.

or maybe you could subclass the plotseries and overload
updateTransform or some other suitable method.

just ideas

I managed to get my similar problem basically working by writing a
fair bit of code that made sure the bound data actually changed. In
my case (which I think was different) I was not quite binding
correctly so the data I was changing was not causing the update. I
haven't cracked it completely and I'm certain that I get situations
where item renderers are "re-used" as new data points occasionally
have the same colour properties as data points which have been removed
from the chart and are inappropriate for their data. All a bit
mysterious I'm afraid.

Is the charting code going open source?

closer (sort of).

yes I did misunderstand what was used for the category axis.

but correcting that hasn't helped, to be honest. setting CategoryAxis
to "id" didn't improve it

however, if I leave out the horizontalAxis and CategoryAxis
completely, it'll fall back to the default of displaying an index - it
provides the correct amount of them so it *is* reading the XML.

RE: [flexcoders] Flex cookbook article: Flex2 XML Reader Can Create UIComponents

Austin et. al. -

 

There are a number of features of MXML that simply can't be replicated
at runtime. Things like script blocks. Other features would be
prohibitively difficult (arbitrary binding expressions, @Embed,
mx:Component, among others).  You could reduce MXML to a
runtime-parsable subset, and I know various people have taken various
approaches to this.  The more you reduce it, the easier it would be to
replicate...removing repeaters, implicit arrays, default properties,
etc. would get you down to something that could be implemented in a
reasonable amount of time.

 

I'm curious...how many people would find runtime MXML to be important to
them?

having it run after being loaded.

This works fine when dataTipMode="single", but it does not work when I

Took a peek at the code, and that looks to be an unfortunately bug on my
part.  Use 'calloutStroke' instead of 'dataTipCalloutStroke' style.  You
might have to set it programmatically:

 

myChart.setStyle("calloutStroke",null);

 

That should solve the problem (and in a more performant way).

RE: [flexcoders] Re: Setting dataTipCalloutStroke="{null}" when dataTipMode="multiple"?

[Ely Greenfield]

 

 

DataTips were really written to be interactive tips, while a lot of
people have asked for functionality that allows you to treat them more
like labels. We hear the request, and are considering ways to update it
for a future release.

 

If I wanted to put labels on the plot items, I'd probably, in increasing
order of difficulty: 

 

1)  Use the data graphics drawing API (see the post on my blog).
Pro: very easy.  Con:  less performant.

2)  Write a custom item renderer. Pro:  more performant, leverages
existing plot series. Con: axes won't automatically make sure there's
enough room for the labels.

3)  Write a custom series (or extension to plot series).  Pro:  best
performance option, best experience (can make the chart axes make room
for labels).  Con:  requires understanding writing custom series.

 

 

Personally, I'd suggest taking a shot at #3.  Writing a custom series
really isn't all that difficult, esp. for a plot series, which is the
simplest kind.  I'd probably try this:

 

1)  Extend PlotSeries.

2)  In the constructor for your extension, create a UIComponent and
addChild it. This will be the sprite that will contain your labels.

3)  Override the get labelLayer property, and return a reference to
that UIComponent.  This makes sure the chart adds it to your display,
above all the series, so labels don't appear under items.

4)  Override updateDisplayList.  First call the super.  Second, for
each chart item in the renderData.filteredCache array, create a Label
(or some custom component), position it where you want relative to the
x/y values in the chart item, and add it as a child to your labelLayer.

5)  Override describeData. This is the method where you tell the
axes what range your data represents.  You also have the option of
telling the series that you need a certain number of pixels on either
size of your data.  You'll want to report to the axis that you need
space to the right of your data for the label.  See the ASDoc for
describeData for more details.

6)  Optimize.  Reuse your labels in your updateDisplayList function,
etc.

7)  Deal with transitions, if you want.  Eearlier I said that in
updateDisplayList, you want to look at the renderData.filteredCache
array. With transitions, it's a little more complicated.  You might have
a transitionRenderData property, in which case you want to use that.
Your transition render data property might have an elementBounds array,
in which case you want to use that instead.  Honestly, in my experience,
it's better to hide labels during transitions, so probably you just want
to see if you have a transitionRenderData value, and hide all your
labels if you do.  See PlotSeries.updateDisplayList for an example of
how to deal with transitions and render data.

Thanks for the reply, Ely! I really appreciate your input. 

> myChart.setStyle("calloutStroke",null);

This works to hide the calloutStroke... ...but the positions of the
dataTip boxes still get offset from the chartItems (in my case, far
away from the DiamondItemRenderers of my plotSeries). In other words,
when dataTipMode="multiple", I want the dataTip boxes to position
themselves like they do when dataTipMode="single": i.e., a few pixels
to the northeast of the chartItem. 

My real end goal is to show the all the items in the plotSeries, with
their corresponding dataTips right next to them (I'm using a high
mouseSensitivity to forcibly show multiple dataTips right now, but I
know I'll eventually have to explicitly dispatch MOUSE_OVER, or else
override findDataPoints and toggle all the showDataTips value to
false/true).

If I can't force the offset-positioning of these dataTips in order to
align nicely with their chartItems, do you think I need to use a
custom ItemRenderer instead? Your "StoplightItemRenderer" example at
qs* is quite helpful in this regard, but I can't figure out how I'd
also draw text values from the chartItem adjacent to the
DiamondItemRenderer (e.g., "Smith,John (age 30)" adjacent to the
diamond graphic).

Thanks again for any suggestions; believe me, little bumps in the road
like this don't take away from the enormous benefit this charting API
has already been for us.

Hmmm...seems to be down right now.  I'll send you're the code directly.

Thanks for the details on the options, especially #3.

> 1) Use the data graphics drawing API (see the post on my blog).

Excellent; I'll start with this (I need to demo a proof-of-concept
this weekend). QuietlyScheming is still refusing my connection,
though (it must know I want to do unsavory things with dataTips).

> 2) Write a custom item renderer

Once I'm in updateDisplayList() and I have access to the _ChartItem,
is it possible to then output the contents of a data field from the
item (e.g. _ChartItem.hitData.item.NAME in a Label to output
"Smith,John" via addChild() or something), or is it restricted to pure
Graphics drawing methods?

> 3) Write a custom series (or extension to plot series)

I like that as my eventual solution; and assuming that the answer to
the above question is "no", I assume this would be the only way to
embed data provider fields (e.g. "Smith,John" from the ChartItem) into
the ItemRenderer?

thanks again,

Can you post very simple sample code? What does your MXML look like?
Etc.

While I am trying to resolve it, if anyone has any clue about it that
will be great. 

 

TypeError: Error #1009: Cannot access a property or method of a null
object reference.

the above exception only comes when I associate an effect
("SeriesInterpolate" in my case)  with the LineSeries.

I printed the values of the dataprovider associated with the LineSeries
and all the values are NOT Null.

RE: [flexcoders] Charting dataTransform.invertTransform() on DateTimeAxis

[Ely Greenfield]

 

 

Nope.  invertTransform converts a position along the axis to a numeric data 
value.  For DTAxis, data values are dates For that matter, DTAxes don’t have a 
dataProvider, so there’s no concept of a dataprovider for them to compare 
against. It’s up to you to use the value returned to search through whatever 
collection/array you’re interested in to find a relevant item.

 

Ely.

Hi,

When implementing the dataTransform.invertTransform() method on a DateTimeAxis 
instance, it seems the return value is the date value represented... is there 
anyway to return the index value of the dataProvider like a CategoryAxis would?

RE: [flexcoders] Custom Chart

[Ely Greenfield]

 

 

 

Sounds like a chart:

 

-  With two separate bar series, one for actual, one for plan

-  Set to 'overlaid' mode

-  The plan series has a custom renderer that just renders a
vertical line, rather than a  whole bar.

 

Ely.

I want to compare plan vs actual cost.

On a bar chart I want a bar to show the actual cost. I also want a
thin vertical line where plan cost was.

The middle graph on the cover of this book shows what I want to do. I
don't need the different shaded backgrounds.

Any ideas?
