I want to make a combo chart as below, could anyone help me with it please?
It has 4 dimentions (A, B,C, D) in a dimention group.
When I choose A and B, it shows the monthly value bars of both A and B, and the percentage line of A/B(divide A by B).
If I choose A,C or B,D or any two of those, the bars and line will change accordingly.
How to wirte the caculation script of line chart?
Thanks a lot.
Anna
