thanks that worked oddsy,
now im facing problem to show the hidden series through
actionscript
im doing something like this:
while generation i hide the series
pasting the function for reference:
public function addSeries(series:Array, yField:String,
id:String, color:uint,dp:ArrayCollection,vis:Boolean):void
var ls:LineSeries= new LineSeries();
var stroke:Stroke = new Stroke()
ls.yField = yField;
ls.xField="ts"
ls.dataProvider=dp
stroke.color = color;
stroke.weight = 1.5;
ls.setStyle("lineStroke", stroke);
ls.alpha=.8
ls.visible=vis
ls.id=id
var temp:Array = series;
temp.push(ls);
series = temp;
mychart.series = series;
thru action script i try this : if checkbox selected do -
> mychart.series[0].visible=true ,
mychart.series[1].visible=true....so on
but it doesn't show the series! what shud i do?
