I have a problem with the Divide function for TH2D.
I have two TH2D defined on the Y range from 1000 to 7000 (I cannot change this). When I Divide these two histo I obtain another TH2D which has values around 1 but it is also automatically defined from 1000 to 7000 so I don’t see anything if I try to plot the histo.
I tried to define the new histo from 0 to 2 but it does not work. Is there another way to obtain the right range for the new TH2D?
Thanks a lot,
