Business Graphics : Capture the value of portion clicked in WDA ABAP

Hi All,

I created a busniess gaphics of type PIE . Please find the scree shot .The business graphics is getting the data from the node ( ZSERIES) .

I created a busniess graphics using category , series and points . I have provided the eventID to the point in the property. Also i have provide READ_DATA in the ONCTION for Busniess graphics .

The data is gettting displayed fine and when i click on the busniess graphics the action method is called . Here i am trying to read the portion which is clicked

but i am only see lead selection data.

On Debugging i found It is only reading the lead selection data and on click of the graphics lead selection is not getting changed.

Objective : if i can capture the value i can do some calulation based on it .

Please provide your valuable inputs .Also let me know if you need more input on the same.

Thanks,

Om
