I would like to rebin the X and Y axes of a 2D histogam using something analogous to:
TH1F::Rebin(Int_t ngroup = 2, const char* newname = “”, const Double_t* xbins = 0)
i.e. passing an array to perform a variable bin width rebinning.
I’ve had a look through the documentation, but I didn’t manage to find any function to do it. Does this functionality exist?
