How can I Drill-Down on multiple pie chart

Hi,

I have 3 fields (1 - 'On change of' and 2 'Show values') and using that I have created a multiple pie chart (please see the screenshot for chart type) however I am unable to do a drill down on it.

Can anyone please let me know on how to add a drill-down when using a multiple-pie chart type.

I would like to add a drill down to those multiple pies so that user can further dill into the data when they click on different pie slices.

Thanks,

Shruthi
