I have a hsitogram h1 with with graphicla cut mygcut.
I can to draw this by:
but how to copy this histogram (with graphicla cut) to new one?
I suppose you would say that h1 is a TTree and mygcut a TCutG.
In this case, you can do, fo example h1->(“x:y>>h”,“mygcut”)
and h is a TH2 taking account your cut.
