There are different forums such as VBA Macros, Data Visulization & Charting, Dashboard etc.
For PT or PPT you can ask your question here, i.e. Ask An Excel Question.
I have posted PPT related question on "Ask An Excel Question" section but wasn't getting any reply so I though I might have posted it in wrong section.
Thanks all, I was worried that I have posted it in wrong thread :D
@ashish mehra yes, i have been reading about powerpivot but doing it, is more difficult
If you download the attached file in my PPT post, example output for one issue is in column "O" and others are inside powerpivot. I'll update my other post with more detail soon.
