Probably a noob question, but:
I have points points that I draw using a TGraph (TGraphErrors) on a Canvas (red points on the picture attached) and I define a closed area (the green triangle).
How is it possible using TCut (or even TCutG) to select (and be able to store the data so they can be manipulated) only the red dots INSIDE that area ??
Thank you very much for your support.
