Issue on clearselection on chart componenet

Hi ,

Am facing issue with chart clearselection method.Requirement is like i have one pie chart and based on the pie chart selection the other combined chart should filter out and for the next selection the existing selection should be cleared .

I tried the following method

CHART_3.clearSelection(); on the onselect event as last statement but its not working as expected am able to see the selection.

Could you please help out here.

thanks
