Alexander,
You can use these functions for all type of histograms and
all dimensions. In case of 2-d and 3-d histograms, however, you
must compute a "linearized bin number" before invoking these
functions. For example for a 3-d histogram, you can do:
Int_t bin = h3->GetBin(binx,biny,binz);
Float_t y = h3->GetBinContent(bin);
