is there a fast (maybe a method which I missed) way to get a “subset” of the channels of a histogram and making a new histogram with that?
I mean, e.g., from a TH2 with 100 bins on both axis I’d like to have a new TH2 made by the 17th to 47th X bin and by the 39th to the 99th bin (without changing the bin specifications like bin width and edges).
If yes, it is also calculating the underflow/overflow bins?
I was writing something that and I wondered if it was already existing as TH2 method…
BTW, it would be worth to have this routine as TH2 method, wouldn’t be?
It seems also a quite standard routine not depended by the “taste” of each user (I do not see any other meaning for asking a TH2 subset…), is it possible to add a method like this as a feature for next versions?
