Hi!
Maybe somebody can help me to brush up my C++ understanding?
I would like to understand the rational of having
TH1::GetCellContent in TH1, but with the restriction of only callable by TH2s (which are TH1s of course),
compared to
TH2::Rebin2D
which resides only in TH2.
So why these two different scenarios, is there a reason?
I’m asking because I’d like to implement a TH2::GetMean2D cause there doesn’t seem to be any method so far, to get the mean over all cell contents, and I would like to know the rationale for where I should put the code, in TH1 or TH2.
Many thanks for reading, you just made a simple post happy!
