Charting based on the current found set is a really nice FileMaker feature. It takes a little work to get the chart just as you want it and that's expected. I'd like to reuse the chart layout with a different found set and do not see a way to do that. The data is much the same except that the found set will be based on more team members over a wider time period.
I've done the due diligence of checking FM 17 Online Help, the Community and even my FM Pro 14 book.
As always, thanks for your suggestions!
