DYNAMIC CREATION OF LINE SERIES USING ACTIONSCRIPT

Question

There's something wierd about flex or im doing something
wrong?
- when i create a line series manually using mxml and specify
a id for the series, it works.
- similarly when i try to dynamically create a line series
using actionscript & define an "id" property, flex does not
understand! what am i doing wrong?
code for reference:
private function addSeries(series:Array,
yField:String,id:String) // addseries(series,"date","1000")
var ls:LineSeries= new LineSeries();
var stroke:Stroke = new Stroke()
ls.yField = yField;
ls.xField="ts"
ls.dataProvider=dp
ls.id=id // tried defining it dynamically, but flex does not
find
this.mychart.series.push(ls)
THIS IS THE ERROR I GET : "TypeError: Error #1010: A term is
undefined and has no properties."

I see... I played around with the line chart ...
Hopefully this helps... if not forgive me...
I know why you are trying to use the id property which i
agree doesn't work.
since the series is an array in your lineChart use the index
to set the visible property false/true.
lineChart.series[0].visible = true/false;
<mx:Lineseries id="a1" visible="true"
dataProvider="{whatever}" />
<mx:Lineseries id="a2" visible="false"
dataProvider="{whatever}"/>
create a function called init();
public function init():void
var lineS1:LineSeries = new LineSeries();
lineS1.visible = true/false;
lineChart.series.push(lineS1);
var lineS2:LineSeries = new LineSeries();
lineS2.visible = true/false;
lineChart.series.push(lineS2);
... and the key is to call this init function on initialize
event...NOT on createComplete event
<mx:LineChart.... initialize="init()" .... />
and to show both lines... call this function...
public function showLines():void
lineChart.series[0].visible = true;
lineChart.series[1].visible = true;
Hope this helps....
