Perspective pie scripting

Dear All
I have a question regarding the pie in perspective

I would like to use pie dynamically, if i press on sector i want to read the label and values for this sector and work with it in another tags, objects.

Right now Iam doing it by the putting lables a top of pie sector and there is onClick event on the label but i would like to move it directly to the pie.

Another thing is when i press mouse button on the pie sector moves out. Is this possible via script or parameter?

Thank you best regards
