Question

the LineSeries is not dynamically added to my CartesianChart…
What’s wrong in this code:

...

 private function chartComplete():void {

                var ls:LineSeries = new LineSeries();      
                ls.styleName = 'timeline';
                ls.dataProvider = "{dataManager.tagViewTimelineModel.tags.getItemAt(0).yearPopularity}";
                ls.yField = 'popularity';
                //ls.s = "{new Stroke(0xCC33CC, 2)}";
                AllChart.series[0] = ls; 
            }

...

<mx:CartesianChart id="AllChart"  width="100%" height="100" creationComplete="chartComplete();">

            <mx:horizontalAxis><mx:CategoryAxis id="horiz1"  dataProvider="['1','2','3','4','5','6','7','8','9','10','11','23','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31']"/></mx:horizontalAxis>
            <mx:horizontalAxisRenderers><mx:AxisRenderer axis="{horiz1}"/></mx:horizontalAxisRenderers>

            <mx:verticalAxis><mx:LinearAxis id="vert1" /></mx:verticalAxis>
            <mx:verticalAxisRenderers><mx:AxisRenderer axis="{vert1}"/></mx:verticalAxisRenderers>

            <mx:series>
                <mx:AreaSeries id="timeArea" styleName="timeArea" name="A" dataProvider="{dataManager.tagViewTimelineModel.tags.getItemAt(2).yearPopularity}" areaStroke="{new Stroke(0x0033CC, 2)}" areaFill="{new SolidColor(0x0033CC, 0.5)}" />


            </mx:series>

            </mx:CartesianChart>

I can only see the TimeLine if I added it with MXML:

<mx:LineSeries styleName="timeLine" dataProvider="{dataManager.tagViewTimelineModel.tags.getItemAt(0).yearPopularity}" yField="popularity" stroke="{new Stroke(0xCC33CC, 2)}"  />

But I need to update the view, and add N lines so I cannot do it with MXML.

thanks

You can set the series property for the chart. Just add a new Series object to that array.
