[flexcoders] Problems with showDataEffect trigger looping on Chart Seris in Flex 3
Has anyone run into this issue in Flex 3?
The showDataEffect is looping endlessly, causing a transtion to run
over and over again.
I have two charts, one a LineChart and one a ColumnChart.
On the series of each, I have set the
showDataEffect="{nameOfEffectHere}"
For the LineChart, the effect is declared as:
For the ColumnChart, it is declared as:
In both cases, the effect loops.
I cannot find what is causing the showDataEffect to be triggered.
This code worked fine in Flex 2.0, but breaks in Flex 3.0.
Any info would be appreciated!!!

It seems this is a knonw bug with Adobe in Flex 3.
If there are nested Arrays, Flex will not handle them properly.
Flex 3.0 also will drop data if the structure of the data is not
ordered exactly as the WSDL dictates. This all wokred fine in Flex
2.0.1. A seriously bad mistake by Adobe to let these bugs slip
through.
So it turns out that switching our Webservice to handle SOAP
responses from 'object' to 'e4x' seems to have solved the problem.
We then used this to set the data back to objects to match the
structure that our Cairngorm responders were expecting:
protected function parseXMLData(xmlData:String) :
Object
{
var xmlDoc:XMLDocument = new XMLDocument(xmlData);
var decoder:SimpleXMLDecoder = new
SimpleXMLDecoder(true);
var obj:Object = decoder.decodeXML(xmlDoc);
var data:Object = new Object;
for(var i:int = 0; i < 2; i++)
{
for each(var tempObj:Object in obj)
{
obj = tempObj;
}
}
data.result = obj
return data;
}
[flexcoders] Webservice implementation switched to e4x after Flex 2.0.1 hotfix 2
Hi there: We've run into some webservice issues here when switching from Flex 2.0.1 (not the hotfix version) to Flex 3. We are retrieving data from a .NET backend using a SOAP/wsdl format. When we switched to Flex 3.0, the structures returned on the repsonse were sometimes a little different. For example, we had a data structure returned that was like this: data.result.UserProfileResponse.snapshots.Calendars Where Calendars was an ArrayCollection. Now the struture comes back without the Calendars part, and the data is in an ArrayCollection under the data.result.UserProfileResponse.snapshots structure. The wsdl loks like this: Is this a result of the changes to implement e4x on webservices? Has anyone else run into this issue? Thanks in advance, Mike

Hi Guys: I am trying to parse a string that is URL encoded, and I want to remove, or decode it. I was surprised that there wasn't something available in a utility class already in AS3. Anyone ever run into this ? I saw a post that had a link to some code that sounds like it would solve my problem: http://tech.groups.yahoo.com/group/flexcoders/message/55312 But the post is missing any code snippets. If anyone has any ideas, please let me know !!! Thanks, Mike
[flexcoders] Re: Flex2 - Bug with chart Legend and ScrollPolicy
I take back my last message. This is still messed up. This only creates scrollbars if the VBox or HBox is smaller than the Legend's display area. As Ely, mentioned, Legend extends from Tile. That's why it has the wrapping going on when a legend has more items than can be displayed in a line. If you have a sizeable legend, I don't see a way currently to add a scrollbar. As an alterantive, you could create a hard coded legend. In my case the items are added dynamically, and the series/legend colors are determined by info in my dataProvider, so i can't hard code a legend. --- In flexcoders@yahoogroups.com, "mgrayfmr" <[EMAIL PROTECTED]> wrote: > > Hey guys: > > Just an update to this problem. > If you put the legend inside a VBox or HBox, and set a fixed > width/height, scrollbars can be added.

[flexcoders] Re: Flex2 - Bug with chart Legend and ScrollPolicy
Hey guys: Just an update to this problem. If you put the legend inside a VBox or HBox, and set a fixed width/height, scrollbars can be added. This assumes the scrollpolicy is set to either 'auto' or 'on'. I tried this out and it worked. The only drawback is you can't use percentages for width and height.

[flexcoders] Re: How to align identical CategoryAxis as HorizontalAxis and SecondHorizontalAxis
Holy cow, I figured it out, and it's stoopid easy. It may not be that apparent at first glance though. All I needed to do was set the padding to 0 for my horizontal axis. It seems that by default, the padding for my top/secondHorizontal axis, which is a CategoryAxis, was 0.5. By Setting it to 0, it now mathches the scaling of my bottom horizontal axis.

[flexcoders] Re: Charting - create a secondSeries with Actionscript 3.0 ???
Thanks Brendan>
I think my problem was caused by me specifying a secondDataProvider
on my LineChart.
Here is a snippet of what worked for me :
My chart is named chLinearChart
var tmpSeriesArrayColl : ArrayCollection;
var ls_P : LineSeries;
var stroke : Stroke;
var tmpFill : LinearGradient;
//Custom ValueObject that holds cahrt data
tmpSeriesArrayColl = ChartDataVO.arrPageByProducerChartData;
for(var k:int = 0; k < tmpSeriesArrayColl.length - 1; k++)
{
ls_P = new LineSeries();
ls_P.displayName = tmpSeriesArrayColl[k].name;
ls_P.yField = 'value';
ls_P.xField = 'time';
//Use the color specified in XML for the stroke
stroke = new Stroke();
stroke.color = tmpSeriesArrayColl[k].color;
stroke.weight = 2;
//My tmpSeriesArrayColl contains a gradient fill I created earlier
tmpFill = tmpSeriesArrayColl[k].fill;
ls_P.setStyle("lineStroke", stroke);
//So the legend dynamically gets the correct color
ls_P.setStyle("fill", tmpSeriesArrayColl[k].color);
ls_P.dataProvider = tmpSeriesArrayColl[k].data;
this.chLinearChart.secondSeries.push(ls_P);

[flexcoders] How to align identical CategoryAxis as HorizontalAxis and SecondHorizontalAxis
Help Ely (or anyone who knows) !!! I'm having trouble with the data being displayed in a LineChart. I have same data in a horizontal and secondhorizontal category axis. I am also displaying vertical gridlines using the backgroundElements property. What is happening is that the spacing is different for the bottom and top axis. The bottom axis is fine but the top is spacing the interval differently than the bottom axis. The gridlines are aligne with the top axis interval. Basically, I end up with data in each series that don't match up because they align to two different axises. Is there a way to control how Flex sets the divlines ? I have tried creating a sub-class of Category axis, but nothing seems to be of help. I have managed to get the top axis labels to display in the correct spacing, but this does not change the actual plot points on the gridlines. Any help would be appreciated !!!

[flexcoders] Charting - create a secondSeries with Actionscript 3.0 ???
Hey Gang - Has anyone had any experience with dynamically adding a second series to a chart using actionscript 3.0 ? Using a LineChart object I have been dynamically creating new LineSeries under the linechart's series with no problem. I am not having luck adding a second series though. The data is fine, it just won't display a second series. To test, I added my secondSeries data to the primary series, and it displays (but realtive to the wrong Y axis, obviously). If anyone has any ideas, I would appreciate it. If I find a solution, I'll post it here as well. Thanks, Mike
[flexcoders] Re: Does anyone know how to set a legendMarkerRenderer dynamically ???
I tried something else on a suggestion, that also did not work, even
though it seems OK.
I created a style sheet entry like this:
.legendRenderer
{
legendMarkerRenderer: ClassReference
("mx.charts.renderers.CircleItemRenderer");
}
I made sure the style sheet was included in my app.
I then set the style of my series like this:
for(var k:int = 0; k < tmpSeriesArrayColl.length - 1; k++)
{
ls = new LineSeries();
ls.displayName = tmpSeriesArrayColl[k].name;
ls.yField = 'value';
ls.xField = 'time';
ls.form = "line";
ls.dataProvider = tmpSeriesArrayColl[k].data;
stroke = new Stroke();
//Use the color specified in XML for the stroke
stroke.color = tmpSeriesArrayColl[k].color;
stroke.weight = 1;
ls.setStyle("lineStroke", stroke);
ls.styleName = "legendRenderer";
this.linechart.series[k] = ls;
}
}
It still complained that the object did not find the IFactory
interface. So it is trying to load my renderer.
It looks like the answer would be to sub-class the renderer and
implement the IFactory interface.
Just thought I would share in case anyone sees this issue.

[flexcoders] Does anyone know how to set a legendMarkerRenderer dynamically ???
I am creating LineSeries objects dynamically, and I want to be able
to use the CircleItemRenderer for the legend.
I tried doing this several ways, but get an error that the renderer
cannot be cast to a type of IFactory. I tried making sure
CircleItemRenderer was imported, and using new CircleItemRenderer(),
but no dice.
I'm doing something like this.
The only line that blows up is the LegendMarkerRenderer.
My array contains series data, a display name, and a color.
for(var k:int = 0; k < ChartDataVO.arrCollSeriesArray.length - 1;
k++)
{
ls = new LineSeries();
ls.displayName = ChartDataVO.arrCollSeriesArray[k].name;
ls.yField = 'value';
ls.xField = 'time';
ls.form = "line";
ls.dataProvider = ChartDataVO.arrCollSeriesArray[k].data;
stroke = new Stroke();
stroke.color = ChartDataVO.arrCollSeriesArray[k].color;
stroke.weight = 1;
ls.setStyle("lineStroke", stroke);
ls.setStyle
("legendMarkerRenderer", "mx.charts.renderers.CircleItemRenderer");
ls.styleName = ChartDataVO.arrCollSeriesArray_AVG[k].key;
this.linechart.series[k] = ls;
}
Anyone have any insights ?
Thanks in advance !!!

[flexcoders] Any ideas on customizing labels an gridlines in LinearAxis of LineChart ?
Hey Guys- I have a line chart with a numeric Y axis that I want to control the number of gridlines. Usually, this isn't a problem but sometimes lines are not drawn in even intervals. My axis data ranges are dynamic. For example, I might have a range of percentages from 88% to 100%. With an interval of 2, I get horizontal lines at 88%, 90%, 92%, 94%, 96%, 98%, 100%. But when the min and max become 87% and 100%, Flex draws axis labels for the same range and leaves off a label for 87% because it is only an interval of 1 away from 88% I need for the min and max values to be displayed on the axis when there are uneven intervals. I have sub-classed the LinearAxis class to manipulate the AxisLabel objects, but I am having a hard time creating even intervals. The two best scenarios I have come up with is 1) a chart with labels 87% ,90%,. . . 100%, but that leaves a larger interval at the bottom of the chart. And 2) check for a modulus (means I don't have an even interval), and alternate the intervals 2, than 3, than 2 again. This creates uneven gridline intervals, even though the chart is accurately displaying the data Ideally, I would like to end up with the second style, with alternating intervals, but have the chart rescale so the intervals appear equal. Just to let you know, I am copying the functionality of an existing Flash Fusion Chart control, so this isn't a completely random idea! The Fusion control asks for the number of divlines you want only, and figures it out from there. A Flex chart though, as you probably know, takes an interval instead. If anyone has any ideas, or has run into anything like this, please let me know !!! Thanks - Mike Gray
