[flexcoders] Re: Exceeding Flash's Capabilities?
66 line series with 218 plot points each for a total of 14388 plot points, if
we're looking for specifics. It's a lot of data that doesn't look particularly
good because of the sheer volume, but it's what they want.
I'm using a line chart. Using AMF3 to retrieve the data. The time it takes to
query the data, or transmit the data, isn't an issue. Also, the problem doesn't
happen over time, it could be the first request someone makes on the
application - I don't believe it's a memory leak.
The method used to populate the graph is thus:
var ls:LineSeries = new LineSeries();
ls.dataProvider = data[o];
ls.yField = "counter";
ls.xField = "dtime";
ls.displayName = o.valueOf();
if ( circleplots.selected ) {
ls.setStyle('itemRenderer', new ClassFactory(CircleItemRenderer));
}
var currentSeries:Array = linechart1.series;
currentSeries.push(ls);
linechart1.series = currentSeries;
Storing the data in an internal array, and possibly sending it to the clip
board isn't a big issue. It's trying to display that much data within a flex
construct that causes the problem(s).

[flexcoders] Exceeding Flash's Capabilities?
The majority of my flex work revolves around graphing data. If for some reason a user picks a lot of statistics to graph, over an even longer period of time, the amount of data that comes back to the Flash application overwhelms flash, consuming all of the boxes resources and regularly crashing the browser. Is there anything in the developers bag of tricks to help with this kind of problem, or is the sheer amount of data too much for the application/SDK/solution to handle? I understand I can put a limit on the amount of data returned, but as the user states, "I can pull it out of the database, via Excel, and it works". Tref
[flexcoders] Empty Combobox with confirmed data in dataProvider
I searched the forum and Google unsuccessfully to see if someone else reported this problem and I came up empty. A while back I posted about questions with AsyncTokens and it was suggested I update my SDK within Flex, I updated to 3.5 from the default Flex SDK version. Since that time, I've had random issues with any app I've rebuilt/updated and pushed out with this new SDK. The problem is simple, I have a bindable variable defined as an Array, with data being pushed into it: userlist = ArrayUtil.toArray(event.result); Within the MXML, the definition is pretty straight forward as well: The problem is, the combobox is never updated with the data. I can throw in debug or trace userlist, and the data is there. This isn't a problem if I compile the application with the older version of the SDK. My only workaround, that I've found, is to set the dataProvider directly, instead of populating the bindable variable: userbox.dataProvider = ArrayUtil.toArray(event.result); Has anyone else seen this? Was I just doing it the "wrong way" the first time, and it just happened to work? Thanks in advance.

But in the case of your fault/result method, it's a simple thing to work around. The way the other responder works, at least in the documentation and code examples I've seen, it's pretty clear how to get the result/fault and the AsyncToken. But in the end, that's not the issue ... if the responder never seems to be called, everything else is moot :\ This is why I'm wondering if you can't wrap AsyncToken calls around AsyncToken calls - if the SDK just gets confused or ignores nesting like that. Either way, closure appears to be working for me right now, which is the important part. Tref

As far as I can tell, it's not a custom class as it's included by default in the SDK. As far as usage, if I use Responder over AsyncResponder, I get the following error: 1067: Implicit coercion of a value of type flash.net:Responder to an unrelated type mx.rpc:IResponder. I'll see if I can figure that out, but AsyncTokens definitely don't seem to like me. Tref

Thanks for the tip, Amy, but it doesn't look any different than what I have.
Additionally, I didnt see any change in behavior from SDK 3.1 to SDK 3.5.
Intentionally brief, here:
import mx.rpc.AsyncToken;
import mx.rpc.AsyncResponder;
var token:AsyncToken = myService.disableStatistics(user,pass,email,tArray);
token.info = email;
token.addResponder(new AsyncResponder(myResults,myFaults,token));
private function myResults(event:Object, token:AsyncToken):void {
var resultEvent:ResultEvent = ResultEvent(event);
}
private function myFaults(event:Object, token:AsyncToken):void {
var faultEvent:FaultEvent = FaultEvent(event);
}
disableStatistics is called, and executes correctly. I see the reply coming
back in but neither myResults nor myFaults is ever called. If I add a listener
...
myService.adddisableStatisticsEventListener(myResultHandlingFunction);
... the listener's result function is called, but I have no token data from the
AsyncToken/AsyncResponder.
Could the problem be due to AsyncTokens being used within the Flex generated
coded based off the WSDL? ie, wrapping AsyncToken calls around other AsyncToken
calls?

[flexcoders] Re: Flex, SOAP and Process Flow
I've given up for now. AsyncTokens appear to be the way to go, but by the documentation I've seen it *should* work, but the result/fault handlers are never hit. I decided to try using 'closure' instead - I'm not even sure if the variables will remain stateful, but it's at least in a forward direction for now.

Yeap, looking at that now and having little luck as well. http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/Flex/Q_23313753.html, for example, shows someone with a similar problem with a similar solution.

If I use addEventListener against myService instead, I get the resulting data, but nothing from the token:AsyncToken. I'm not comfortable that I have the AsyncToken set up properly, since it doesnt make sense to make the call to myService before 'email' or 'addResponder' is issued, which is what I'm playing with right now.

Unfortunately, this example doesn't appear to work for me. It uses the Flex-built SOAP code and an AsyncToken to keep track of things.

[flexcoders] Re: Flex, SOAP and Process Flow
That makes sense if you can control the data that is sent back to you from the
first resultevent (but I can't).
1) Web call - Does the user 'Trefalgar' exist?
2) Web reply - No. (no additional data)
3) Web call - Create user 'Trefalgar'
Flex doesnt appear to be linear. That said, since #2 doesn't tell me what user
it's replying "no" to, if I do this in a loop with 100 users, it could be
replying back with 20 "no"s and I can't tell how I'd match the replies up with
the requests.
Is there a solution for this problem in Flex/AS? I don't think putting the
secondary calls in the resultevent would work, when critical information needed
for future calls isn't available in the resultevent.

[flexcoders] Flex, SOAP and Process Flow
I've run into an odd problem that I haven't been able to find a solution to. In
other programming languages (Perl, PHP, for example), if I want to do X, Y and
Z in order, all with remote calls, it's very easy and straight forward. With
Flex, I'm pretty confused on how to do something this simple. Here's the
problem and why I'm confused ...
I'm using Flex and SOAP to talk to a web interface. In order to get to step Y,
I have to first do step X. I can not skip to step Y without step X being
complete. But setting up the flow to be two subroutine calls, X first, then Y,
doesn't mean that X finishes first (and lately means Y actually finishes first).
callX(var1,var2);
callY(var3,var4);
Since Flex uses listeners, and not return() how do you pass data around to know
that X is complete?
callX(var1,var2);
{wait for callX to be finished, before continuing}
callY(var3,var4);
How do you pass data around successfully to do that check? Does my problem
description make any sense or is my brain fried? ;)

[flexcoders] Copying linechart series to clipboard
Copying data from a datagrid to a clipboard is easy - tons of examples, lots of methods, it's in a predictable format. What about copying data from a series? Generally speaking, a single line would be easy. Adding lines would be easy, if they had identical hAxis values. The difficulty comes in when you have missing values in some series that the linechart would just draw a line through while connecting the two surrounding, non-missing, points. This would cause the number of values to be less when copied, thus throwing off a simple grab like you do for datagrids. The only thing I can come up with is to copy each line individually with its own header/legend. Has anyone had to tackle this problem before? Any suggestions? Tref

Sorry if this is a double post, but it seems that when you ask the question,

I am taking an array of objects and using it to dynamically create a list of

if ( fields.length > 1 ) {
for each (var item:Object in fields) {

var ctextinput:TextInput = new TextInput;

It works just fine. On the panel I get a list of {text}:, followed by the
actual textinput field. The only problem is I can't figure out how to reference
those textinputs now that they're created! I've searched through a debug

[flexcoders] Datagrids, radiobutton and scrolling
I remember reading an article that talked about this problem, but I can't seem to find it again. I have some radio buttons in a item renderer for a datagrid. Flex, for a reason beyond me, doesn't keep track of radio button values on a per-row basis in a datagrid - it keeps track of them based on the position in the window. So, if you select a single radio button, scroll down a few pages, you'll find another row with a radio button selected, even though you never selected it. I know this has been addressed, but for the life of me I can't find any articles about it again. Can anyone point me in the right direction to fix this problem? Tref

[flexcoders] Variables to reference variables/ids (not variable variables)
Might be a newbie question, but I'm failing to find this subject in my book or
on the web.
While you can do variable variables, to create all sorts of fun things, I'm
looking to create a variable to reference an object already created.
For example ... I have 10 charts on a reporting interface, each with their own
id and tab. Right now, if I want to make identical buttons affect individual
charts, I'd have to create 10 buttons, each programed to update each individual
chart. What I'd like to do is be able to pass the tab name / chart id to the
function call, so it will know which chart to update.
This way, I only have to create one function to update any chart, instead of 10
functions, one to handle each button/chart.
Does that make sense? Is it possible?
chart = 'linechart0';
{chart}.series = currentSeries;
Tref
[flexcoders] Re: What's wrong with this linechart?
I ended up doing this ...
ca3a.splice.apply(ca3a,[ca3a.length,0].concat(data[obj]));
ca3a.sortOn("loadval");
ca3.dataProvider = ca3a;
... for each possible axis. Seems like there should be an easier way to do
this, without having to define temporary holding variables. This solution also
ends up with duplicates (since each line is added separately, they should at
some point have horizontal values that are the same), which causes the graph to
do all sorts of fun things.

Absolutely right. That's annoying ;)
I'm now trying to figure out how to dynamically take the current CatagoryAxis
dataProvider and append additional data to it. Probably my fault for not

private function graphSetup(data:Object, chart:String):void {

ca1.dataProvider.push doesn't work, it actually ends up setting
ca1.dataProvider to null. I can't do this, either ...
var moo:Array = ca1.dataProvider;
moo.push(data[obj]);
ca1.dataProvider = moo;
If I ... ca1.dataProvider = data[obj] ... it works but for just a single line
series.

[flexcoders] What's wrong with this linechart?
I've got two charts, one is 99% mxml (the 1% is actionscript defining
the datasource definition), the other is mostly actionscript. The mxml
works, the actionscript does not. Does anyone have any idea what in the
world I'm doing wrong?
I'd appreciate any pointers, despite how much it could sting.

I don't understand how a dataFunction could help put data on the correct axis, when it just formats the data for reading the xField and yField. I'm not saying it doesn't/can't work, I just can't visualize how it works, so it's a big stumbling block. The point of the reply, however, is the new 3.3 SDK: axis system now supports multiple axes Obviously something changed to support multiple axes and I'm trying to track down the changes. If you happen to have already found them, I'd appreciate a code snip or pointing to the doc that explains the change. Tref

Negative. The xField and yField are defined globally within the data returned
to the flex application:
for ( var o:Object in event.result ) {
var ls:LineSeries = new LineSeries();
ls.dataProvider = event.result[o];
ls.yField = "counter";
ls.xField = "dtime";
ls.displayName = o.valueOf();
ls.setStyle('itemRenderer', new
ClassFactory(CircleItemRenderer));
var currentSeries:Array = linechart1.series;
var temp:String = o.valueOf();
var index:int = temp.indexOf("scc");
if ( index != -1 ) {
ar=new AxisRenderer();
ar.axis=la;
renderers.push(ar);
} else {
}
var la:LinearAxis = new LinearAxis();
/* first salesperson will show 0-whatever, subsequent ones will
start at the lowest value */
la.baseAtZero = false;
ls.verticalAxis = la;
currentSeries.push(ls);
linechart1.series = currentSeries;
}
linechart1.verticalAxisRenderers = renderers;

--- In flexcoders@yahoogroups.com, "Amy" wrote: > I think you just need to play with the dataFunctions and/or > labelfunctions on the axes until you get what you want. DataFunction sets the data up to be graphed on the line (sets the yField and xField). The lines are graphing fine, just not on the right axis. LabelFunction sets the label/title, what to display along the axis or legend as desired. I'm not having a labeling problem. Unless I'm reading something wrong, neither actually ties data to one particular axis or another. I think what I'm doing is doable in mxml (as found in examples in Adobe's help sections), if you have a static number of series, but if you're doing a possibly unlimited number (or X+1), mxml isn't a scalable solution.

I'm getting close. I've got the lines graphing, but each line is on a
different axis (I'll attach the code below). It only displays two
axises (which is what I want), but it's obvious that there's more than
two since I have 4 lines, all with a value of 1, appearing one above
the other (not on the same dot).
I need a way to bind multiple rows to a single axis, I just haven't
stumbled across it yet.
As always, suggestions are welcome ;)

Below is what I've ended up with. Allowing each line to have its own
axis, it does adjust each max/min axis as expected, but I don't get a
line on the actual graph. If I use the below code, I get the two
axises like I want, but the default axis isn't adjusting to the lines
that I think are latched to it (I also still don't get any lines on
the graph).
In debug, I can see that each series has the data in it for each
datapoint/line that should be graphed. I'm not certain why it's not
being displayed.
labase is defined as the default verticalaxis within the MXML.
Any suggestions?

[flexcoders] Adding verticalaxis(es) via actionscript
I'm having a rough time getting data to auto-scale to multiple vertical
axises. If I use a single axis, the data is graphed without a problem -
all the lines show up exactly as they should. The problem I'm trying to
solve is that one of the lines is ~100, while the others are less than
20. I'd like to get the ~100 line (I know which one it is ahead of time)
on its own axis, so it doesn't skew the graph. I can add a second axis,
but no matter what I try, or what examples I scrape off of, I can't seem
to get the data to 'bind' to the second axis. var
ar:AxisRenderer=new AxisRenderer();
for ( var o:Object in event.result ) {
var ls:LineSeries = new LineSeries();
ls.dataProvider = event.result[o];
ls.yField = "counter";
ls.xField = "dtime";
ls.displayName = o.valueOf();
// Create a verticle axis for SCC
var s:String = o.valueOf();
var index:int = s.indexOf("scc");
if ( index != -1 ) {
var la:LinearAxis = new LinearAxis();
la.title = 'SCC KPI';
la.baseAtZero = false;
ls.verticalAxis = la;
ar = new AxisRenderer();
ar.axis=la;
linechart1.verticalAxisRenderers.push(ar);
} else {
//ls.verticalAxis = ar1;
}
var currentSeries:Array = linechart1.series;
currentSeries.push(ls);
linechart1.series = currentSeries;
// Create a DateTimeAxis horizontal axis.
var hAxis:DateTimeAxis = new DateTimeAxis();
hAxis.dataUnits = "minutes";
//hAxis.labelUnits = "weeks";
// Set this to false to display the leftmost label.
hAxis.alignLabelsToUnits = false;
// Take the date in its current format and create a Date
// object from it.
hAxis.parseFunction = createDate;
hAxis.labelFunction = labelParser;
linechart1.horizontalAxis = hAxis;
}
Any suggestions?

ps. As a side question, if someone can fill me in on how to get the
style on an added axis to look like the 'default' flex axis it would be
a big help as well.
