I'm trying to create a pie-chart, which disregards a certain selection. I have two list-boxes (customers and products) and in the middle of all a pie-chart. This one should only be modified by the customers-selection, not by the products-selection.
How I'm able to do that?
Here is the expression of pie-chart:
FABS(SUM (SALES)) / FABS(SUM(TOTAL SALES))
I thought abou Set Analysis, but how I could achieve what I need? Where to implement? Many questions and many gaps in my mind.
