[EddieBerman]

I understand your frustration. I've been through it myself. In the end, I found 
that I got better results by creating the charts through action script. 
Granted, it takes a little longer and there's a lot more to learn, but because 
you're combining line and columns AND changing the chart type at run-time, 
there may not be a simple MXML-only solution.

[flexcoders] Re: ColumnChart & LineSeries Bug?

[EddieBerman]

I began creating an example for you and unfortunately discovered another
bug further down the chain that had to do with stacking the columns.
Rather than diagnose that now, here's a great blog article I found a
while back that may be a better starting point, particularly since
you'll get past the other annoying flex bug that messes with the visual
spacing between columns when combining lines and columns.
http://flexxxed.wordpress.com/2009/05/20/using-right-chart-when-you-have\
-multiple-chart-series/
<http://flexxxed.wordpress.com/2009/05/20/using-right-chart-when-you-hav\
e-multiple-chart-series/>
And just an FYI - I've run into so many bugs changing from clustered to
stacked to 100% at runtime that I ultimately chose to simply have
multiple charts, one of each type, that I hide/show as needed. It's a
headache, but since the bugs I've logged in the Adobe bug base haven't
yet been addressed, it's the best solution for us. You may be luckier
depending on your needs.

[flexcoders] Re: ColumnChart & LineSeries Bug?

[EddieBerman]

It's a flex bug. It fails in applySeriesSet() in ColumnChart.as. The case 
statement for "stacked" and "100%" assumes that the series is a column series 
and chokes on the line:

seriesSet[i].offset = 0;

as there's no offset for lines series. You can get past this problem by 
extending ColumnChart.as and overriding this function, filtering for line 
series.

[flexcoders] Re: Simple chart data tip question

[EddieBerman]

You can add a callback function on your chart to return any text you'd
like.
Look into the "dataTipFunction" here:

[flexcoders] Re: AxisRenderer Error #1009: Cannot access a property or method of a null object reference

[EddieBerman]

I have no solution for you, but have come across this problem as well. If you 
have a simple app that demonstrates this error, you should create a new bug on 
the Adobe Bug Base and attach the code. My app is too huge at this point, and I 
haven't yet distilled it down to a submittable size.

This is due to a Flex bug
(https://bugs.adobe.com/jira/browse/FLEXDMV-1957
  )
which I'd love to see fixed.

Until then, here's one solution that I found:

[flexcoders] Re: Possible to create a chart with clustered & overlaid columns? (picture inside)

[EddieBerman]

While I haven't yet attempted that layout, here are my thoughts on one
potential path:

You'll need 5 series, with the first one (series 0) being the composite
(as the series are drawn from 0 to n, and if the composite column was
the last one it would draw over the previous columns).

You'll need to adjust the individual series columnWidthRatios and
offsets so that series 0 and series 1 start at the same x position, and
(obviously) series 1-4 take up the space of 5 series columns.

You'll need to have an itemRenderer for series 0. Override
updateDisplayList() and set the unscaledWidth to be wide enough to span
series 1-4.

Here are some potentially helpful links:
1) demonstrates tampering with columnWidthRatio and offsets:
http://www.stretchmedia.ca/code_examples/offset_calculator/SeriesOffsetC\
alculator.html


2) QuietlyScheming shows an example of complex stacking which you'll
need since series 0 is a composite:
  http://demo.quietlyscheming.com/ChartSampler/app.html


That's only a start as you'll still need to also create a custom legend
and deal with the challenge of having the first 4 clusters blue-ish and
the next 4 orange-y.  Having custom itemRenderers should help with that
coloring issue.

Good luck!

[flexcoders] BarChart - CartesianDataCanvas lifecycle problem

[EddieBerman]

Due to a bug that causes chart item labels to not appear
(https://bugs.adobe.com/jira/browse/FLEXDMV-2158
  ), I'm having to
create my own chart item labels.  Though a simple approach is to add
labels to the itemRenderers, I can't use that method in this particular
instance.
Instead, I'm looking at using a CartesianDataCanvas annotationElement
that contains an array of labels.
Since the chart displays real-time data that updates every 5 seconds,
the thought was to use the chart's updateComplete event to first set the
label's text and then position each label using updateDataChild().
The problem is that this causes another update cycle of the chart
itself, which becomes an unending loop.
Is there a way to set the text and position of a label on the
CartesianDataCanvas as the absolute last step of the update process such
that it won't restart the updating process?

Thanks in advance.

[flexcoders] Adobe Bug System - Please explain the internal "Found in Version" numbers

[EddieBerman]

When adding new bugs to the Adobe Bug System (chart bugs in my case), I'm never 
entirely clear as to what version to use from those offered in the drop-down. 
I'd like to use, for example, SDK 3.3.0, but that's not one of the choices. 

I have no idea what I12, I12, DMV 3.0.2, DMV 3.4.0, etc, are so I leave the 
field blank, and then note my SDK version in the Steps To Reproduce. I've 
searched for clues, but can't find one.

I suspect I'm not the only one dealing with this. Thanks in advance for 
deciphering the list.

Cheers,
Eddie B.

[flexcoders] How do I assign a custom CartesianTransform to a ColumnChart?

[EddieBerman]

Anyone with CartesianTransform knowledge?

I'm having a good bit of difficulty getting a dynamically assigned custom
CartesianTransform to work. I'm not finding a whole lot of sample code to learn
from and am currently slogging through the framework code trying to determine
what's up.

The problem is that once I assign the new Transform, the columns no longer
display. It seems that the new Tranform doesn't seem to have the needed
ColumnSeries data. Why this data isn't assigned when the Transform is created
and attached to the series is a bit of a mystery. Is there another step needed,
or is this a bug?


Hopefully someone with more knowledge or experience can point me in the right
direction.
I just spent way too much time with a related dataTransform issue before I
realized that it was indeed an unreported bug
(https://bugs.adobe.com/jira/browse/FLEXDMV-2103), and I'd prefer to know more
quickly if this too is a bug, or just inexperience.

I've made a simple demo to demonstrate the problem. The code is below.

Thanks in advance.
Eddie B.

Steps:
1) Compile and run the 2 files below (main app and custom transform)
2) Click the Change Data button to see that the data changes correctly.
3) Click the Set Transforms button to assign the new transform.
4) Click the Change Data button again to see the columns fail to display.

[flexcoders] To Adobe Folks - General Question About Using Deprecated Tags

[EddieBerman]

I posted a related question here a few days back ("ColumnCharts - problem 
adding a LineSeries to ColumnChart w/o SecondSeries"), but this question is a 
bit more general.

In order get past this bug - https://bugs.adobe.com/jira/browse/FLEXDMV-1957, 
I'm likely going to need to use the deprecated SecondSeries tag. My question is 
how safe is using this, or any of the other deprecated tags, methods, etc.  I 
read what I could find in the docs, but what I saw seemed more focused on 
layout style differences.

Is there an expectation that support could be dropped in future versions, or 
are these warnings simply there to point us to the newer, improved-upon 
replacements.

Thanks,
Eddie B.

[flexcoders] ColumnCharts - problem adding a LineSeries to ColumnChart w/o SecondSeries

[EddieBerman]

I'm trying to add a LineSeries to a ColumnChart. The problem is that for each 
LineSeries added, a "ghost" series of columns is also added. 

This doesn't happen if I add a LineSeries via the SecondSeries tag, but I'm 
trying to avoid that since it's been deprecated.

Is there a way to avoid the ghost column series? Am I doing something wrong? To 
better visualize the problem, look at this Adobe doc page:
http://livedocs.adobe.com/flex/3/html/help.html?content=charts_types_12.html

Notice how the columns in the very top image are adjacent, unlike the two 
examples below it which both contain "placeholders" for the added series, which 
won't ever be drawn since the series is actually the LineSeries floating on top.

Any help or alternative solutions very much appreciated.

[flexcoders] Re: Chart Axis Location

[EddieBerman]

If I understand correctly, you want to:
1) turn off all ticks
(http://livedocs.adobe.com/flex/3/html/help.html?content=charts_formatting_04.html)


2) move the horizontal AxisRenderer. Ex:
myHorizAxisRenderer.move(myHorizAxisRenderer.x, yourNewYPos);


Keep in mind that you can set the placement for the horizontal
AxisRenderer to initially be at the top of your chart. Then just move
it down as needed to overlap the top of the chart.

[flexcoders] Re: Flex chart zoom according to series

[EddieBerman]

One idea - don't bind your legend to your chart. Create your own
legend. To get the color, query your series fill style (once both
series have initially been created), or just use the Halo colors
array. An example:

for (var i:int = 0; i < array.length; i++) {
var color:uint;
var legItem:LegendItem = new LegendItem();
legend.addChild(legItem);
legItem.label = array[i]
legItem.setStyle("fill", determineYourColorHere...)
legItem.setStyle("fontSize", 12);
}

[flexcoders] Re: Removing extreme ends of an Axis

[EddieBerman]

The good news is that it's not a bug. 
Just add caps="none" to your xAxisStroke definition.

[flexcoders] Re: Drawing on Charts - pixel perfection?

[EddieBerman]

Sounds like you've solved your problem, but my take is that for pixel
drawing you'd be better off using a ChartElement object rather than
the DataDrawingCanvas which is an abstraction more appropriate for
data coords. 

For example - take a look at the framework code in GridLines.as. It's
all pixel-based drawing.
You can extend GridLines and do your own addtional drawing in update
DisplayList() after calling super.updateDisplayList(). 

Or create a completely separate backgroundElement using a class
extended from ChartElement.

...just some more options.

[flexcoders] Re: The trouble with Alert.show()

[EddieBerman]

I can't help with the Alert issue, but since I often debug within a 
wrapper, here's one alternative that provides a constant, simple 
debug window. I can't remember, but I might've grabbed it from this 
forum originally.

Paste the code below in your app.
Call showWindow() to activate the window.
Call debug("your text here")  for your debug text.
Good luck.

import mx.events.*;
import mx.containers.*;
import mx.controls.*;
import mx.managers.PopUpManager;

private var _window:TitleWindow;
private var debugText:TextArea = new TextArea();
private function showWindow():void {
debugText.height = 600;
debugText.width= 400;
_window = TitleWindow(PopUpManager.createPopUp(this, 
TitleWindow));
_window.addChild(debugText);
_window.showCloseButton = true; 
_window.addEventListener(CloseEvent.CLOSE,closeHandler);
}
public function debug(str:String):void {
if (debugText.text.length > 1000)
debugText.text = "";
debugText.text += str;
}
private function closeHandler(event:CloseEvent):void {
PopUpManager.removePopUp(_window);
}

[flexcoders] Chart ItemRenderer - Seeking Confirmation of this Bad Memory Leak Queue Bug

[EddieBerman]

I submitted this issue to the Adobe Flex Bug Mgmt System a few weeks
back but haven't as yet seen a comment, nor did my last post on this
forum yield a response, so I'm going to give it another go here.

The problem I'm seeing is that it appears that you cannot dynamically
switch itemRenderers on a chart series at runtime. Or rather - you 
can code it, and run it, but any and all previous itemRenderers 
continue to remain active. As your initial graphics command is likely 
to be Graphics.clear(), you may not notice the problem since each
itemRenderer clears the previous itemRenderer's drawing, BUT under
the covers continued switching of itemRenderers will simply add 
itemRenderers to the priorityQueue, eating memory and slowing things
down along the way. ItemRenderers are never removed from the queue.

I'm hoping someone with knowledge, or at least interest, could weigh
in and let me know if indeed it's a bug, or if I'm coding this
incorrectly, or if there's an alternative approach, etc...

More info, a screenshot of a huge priorityQueue, and sample code can
be found in my bug report:

[flexcoders] Why does changing a chart's itemRenderer at runtime call BOTH itemRenderers?

[EddieBerman]

At runtime, I'm changing the itemRenderer on my column chart's series
based on the value of a checkbox. Pretty simple. Unfortunately, it
appears to me that both itemRenderers - the previous and the current -
are getting called. 

Prior to changing the itemRenderer, I clear the series style, but that
doesn't seem to help. The more often I change the itemRenderers, the
more they stack up, with each replaced one getting called prior to the
actual assigned one.

So - either this is a bug (haven't found it yet in the bugbase, but
there are quite a few to sort through), or there's additional code
that I need to ensure that changing an itemRenderer at runtime
actually does a replace, rather than an add.

The code to swap them is pretty simple (column0 refers to a
ColumnSeries), but here it is anyway:

column0.clearStyle("itemRenderer");
if (chkbox.selected) 
column0.setStyle("itemRenderer", new ClassFactory(Renderer1));  
else
column0.setStyle("itemRenderer", new ClassFactory(Renderer2));  


Can anyone clue me in here?
I've written a very basic sample to demonstrate this problem if it's
needed, but the above code pretty much says it all.
Thanks,
Eddie

[flexcoders] Stacked Charts - Series[0].items.length not accurate at certain times. Bug or ?

[EddieBerman]

I've got a ColumnChart with its type set to stacked. I also have a
BackgroundElement extended from CartesianDataCanvas, which I'll call
myDataCanvas.

There are times, particularly when the myDataCanvas
updateDisplayList() is called, where it's not possible to get the
items of Series[0]. I can get the items of Series[1] and above, but
not Series[0]. Series[0].items.length will show as 0 (yet you can see
the entire series items array in the debugger's Variables pane!).

This isn't a problem when it's clustered, only when stacked.

I can reproduce this easily in sample apps, and can include code if
need be, but I was curious if perhaps anyone else has experienced this
problem, and/or can offer some guidance towards a solution. 


Thanks in advance.

[flexcoders] Charts - how do I draw on a Background Element and NOT cause a refresh?

[EddieBerman]

I've got a column chart with 2 BackgroundElements.
One is extended from GridLines and the other, which sits between the
grid and the columns (in the z-order) is extended from the 
CartesianDataCanvas class. Each ColumnSeries has an itemRenderer. 

I need to be able to draw on the my CartesianDataCanvas object WITHOUT
it causing a redrawing of the series objects. Is this at all possible?

Thanks in advance.

[flexcoders] Need info about my CartesianDataCanvas updating problem.

[EddieBerman]

08/07/2008 05:29:00 AM New Messages

Reply  | Quote  | Top  | Bottom  | Edit

I've got a ColumnChart. In it I've extended the grid to add code to
its updateDisplayList(). At the end of that method I want to notify
another custom BackgroundElement that it should draw itself as well.
This other custom BackgroundElement, which is extended from
CartesianDataCanvas, is in front of the grid in the z-order.

I'm initially looking to learn why my custom Background element
(extended from CartesianDataCanvas) doesn't have its
updateDisplayList() called by default. Is there a property that I'm
not aware of that would force the layout code to call its
updateDisplayList()?  I was surprised that it wasn't being called.

If the above can't be made to happen, I'm looking for ideas on how I
can have the grid notify the CartesianDataCanvas to draw itself, but
WITHOUT that action then causing the grid to be invalidated, forcing
it to then redraw itself, in an unending cycle.


Any info or pointers to information would be most appreciated.

[flexcoders] Re: Chart: pass info about series1 to series2 lineSegmentRenderer callback?

[EddieBerman]

I don't believe you can pass params. An alternative would be to have
your lineRenderer query upwards for the data. I do something similar
and added the following code in my updateDisplayList();

(I don't know how important the initial "LineSeries" check is)
override protected function updateDisplayList(wd:Number,ht:Number) {
var lc:LineChart;
if (parent is UIComponent) {
var myParent:String = String(UIComponent(parent).className);
if (myParent !="LineSeries")
return;

var ls:LineSeries = parent as LineSeries;
lc = ls.owner as LineChart;
var salesInfo:Number = lc.getSalesInfo();  // talk to lineChart here

[flexcoders] 3D Column Chart - Is there a way to set the item update order?

[EddieBerman]

I'm building a 3D column chart and am finding that I need to draw the
columns in a specific order other than the default, which appears to
be by series.

Things go just fine until the z-order depth is greater than the
distance between the series. Once that occurs, the potential exists
for things to go south. 

Images of the problem are here:
http://picasaweb.google.com/eddieberman/Flex/photo#5225608935449236386
and the preferred result here:
http://picasaweb.google.com/eddieberman/Flex/photo#5225608932592265602


My question is - Is there a way to define, or otherwise take over the
drawing order of the ColumnSeriesItems? I want to draw the columns in
the order they appear from left to right, but Flex seems to want to
draw by order of series - first Series1, then Series2, then Series3, etc.

In looking through the Adobe source code, I haven't found a way around
this - yet. 


Thanks in advance for anyone who might have clues to share.

[flexcoders] How can a Line Chart pass data to a custom LineRenderer?

[EddieBerman]

I've got a Line Chart, and I've written a custom Line Renderer. I have 
some chart data to share with the Renderer (apart from the chart value 
data that's available in the Renderer by default), but I can't figure 
out how to either have the Line Chart pass it to the Line Renderer, or 
have the Line Renderer ask the Line Chart for it.

This is a new area for me and I'd appreciate any help here, even just 
pointing me to any existing reference material or discussion that so 
far as eluded my searches. 

Thanks in advance.

[flexcoders] Re: Stack Chart ItemClick detail?

[EddieBerman]

I couldn't find that info either. The solution I'm using, until I
learn of a more direct way, is to assign a number to the ColumnSeries
Name property when I create each ColumnSeries (I happen to use
"Series0", "Series1", "Series2", etc). 

Here's the relevant code fragmants for creating, and then accessing
the column number.

// Creating the columns
private const SeriesName:String = "Series"; 
for (var c:int = 1; c < seriesCount; c++) {
var cs:ColumnSeries = new ColumnSeries();
cs.name = SeriesName + id;  // "Series0", "Series1", "Series2",etc
etc...
}

// Accessing the clicked column's data
public function chartItemSelected (e:ChartItemEvent):void
{
// extract the number after "Series"
var str:String =
e.hitData.chartItem.element.name.substr(SeriesName.length,  
e.hitData.chartItem.element.name.length);
var colNum:Number = parseInt(str);
}

Hope that helps, and/or we learn of a better way.

[flexcoders] How do I access the ClassFactory property from my chart's custom LineRenderer?

[EddieBerman]

I've created a custom LineSegmentRenderer class for my Line Chart. It
works fine using a hard-coded color value for the line it draws.
However, I want this color value to be dynamic. I've passed a color
value property to this class (extended from LineRenderer), but am not
understanding how to access this property from within my LineRenderer
class.

>From the LineChart, I'm setting the property this way:
  var factory:ClassFactory = new ClassFactory(MyLineRenderer);
  factory.properties = { lineColor: "0xFF" };


The questin is, how do I go about accessing my property from inside
MyLineRenderer? Or even better - where can I read more about this.
I've done quite a bit of searching, but haven't found much info.

Thanks in advance.


  

[flexcoders] Charts - Problem accessing dynamically created Axis. How do I.....

[EddieBerman]

I'm changing my code to create my column chart entirely via AS3, rather 
than using MXML tags. Everything works fine except I can't figure out 
how to access my linear and category axis at runtime. When built using 
mxml tags, these have id's that I can use to, for example, change the 
labelFunction:

AS3:
   ca1.labelFunction=myNewLabelFunction;

MXML:
   
 
   


However, when creating the Axis objects in AS3, you can't set id's to 
the Category (or linear, etc) Axis. So, once they're created, I'm not 
seeing how to then access these objects. Probably simple, but I can't 
seem to find anything helpful in the docs (I'm using Flex 3 Beta 3).  
Can anyone point me to the correct method?

Thanks in advance,
Ed

[flexcoders] ColumnChart - creating multiple Linear Axis via ActionScript - Help!

[EddieBerman]

I'm having difficulty understanding how to create, via AS3, a
ColumnChart that contains multiple verticalAxis. I'm familiar with the
sample program "MultipleAxis" provided by Adobe, but can't correctly
translate this to AS3 code. All is good until I need to create and set
the multiple AxisRenderer objects. Can anyone more familiar give me a
suggestion, or point to any reference material for doing this in AS3?
Thanks.

I've pasted the Adobe MXML sample code below that I'd like to replicate:


  



  



  
  



  









  

[flexcoders] Re: Chart Bug? Setting a backgroundElement bitmap at runtime

[EddieBerman]

Let me just clarify the specific bit of code that I assumed would 
work, but isn't. At runtime, way after creationComplete(), I create 
an mx:Image object, load a .jpg into it from my local file system, 
and then push it onto the backgroundElements array. I've also tried 
simply setting it as the sole member of that backgroundElements 
array. The only thing I know for certain is that when I test the .jpg 
loading by adding that mx:Image to the canvas, it displays correctly. 

Since I'm not having success, I'm wondering if this is a chart bug. 
Or - if there's another (or rather, a correct) way to accomplish this 
goal. I couldn't find any mention of this method in the Flex LiveDocs.

Thanks again.

[flexcoders] Chart Bug? Setting a backgroundElement bitmap at runtime

[EddieBerman]

Flex 3 newbie here with a problem I can't seem to solve by myself. 

I've been unable to set a backgroundElement bitmap with an image 
loaded at runtime. 

I can accomplish it without problem using either:

1) an mx:Image with a predefined @Embed source property within 
mx:backgroundElements tags   (as is well documented)

  and/or

2) AS3 code to explicitly push an Embed'd image (also well 
documented).

But - I can't seem to set an image that I load at runtime. I load the 
image and (to test it) display it in an mx:Image object that I create 
at the same time. Then, either I don't know exactly what type of 
object to push into the backgroundElements array, or Flex doesn't 
support this. I've tried using bitmaps, images, etc, but nothing 
seems to work.  I also can't find any documentation for this method.

Can anyone point me to either a reference, or suggest a way to 
accomplish this? 
Much appreciated.

[flexcoders] How can I have my chart's FillFunction return the default fill color?

[EddieBerman]

In my bar (and column) chart, I'm using a fillFunction to change only 
certain bar colors under certain conditions. For those bars that don't 
require a change, I'd like return the default fill color. The problem 
is I can't determine how to access that original color to return. Nor 
can I figure out how to return a value that tells flex to "use the 
default".

Anyone have any useful info here? Thanks in advance.
