[flexcoders] How can I get my CircleItemRenderer to work with SeriesInterpolate?

[sailorsea21]

Hi everyone, how can I get my CircleItemRenderer to work with my 
interpolate on a LineSeries??? If I remove the Interpolate, the 
ItemRenderer works fine but when I add the Interpolate, the 
itemRenderer disapears??? 

Do I need to import anything to make this work??? (import mx.charts...)

This is my script.

<mx:SeriesInterpolate id="seriesInterpolate" duration="1500"/>          
(...)
<mx:series>
<mx:ColumnSeries showDataEffect="{seriesInterpolate}" yField="TOTAL" 
displayName="TOTAL"/>                                           
<mx:LineSeries showDataEffect="{seriesInterpolate}" 
temRenderer="mx.charts.renderers.CircleItemRenderer" yField="TOTAL2 
displayName="TOTAL (2)"/>       
</mx:series>
                        
Thanks.
