How to display affected press in a pie chart using qlikview

Hi Experts,

 

My requirement is to display affected press under each region when we select a particular change using qlikview.

Currently I am using the below expression:

 if([RFC Number]=[RFC Number],[Affected Press])

But this works only for a region with one affected press.

If press is more than one it won't display.

Displaying the affected press name under the sum of labour label or as a popup or anything is fine.

Could u suggest me a solution.

Attaching the picture of current scenario.

 

Thanks & Regards,
