I think the SetBin function must be overruled > in TH1F (and TH1S and ...) > Wouter, The TH1::SetBins function has the user interface to change the number of bins and the histogram limits. This function is currently used in TTree::Draw, for example, to redefine the histogram limits. Changing the number of bins is not implemented. I agree that this should be protected and can only be implemented in redefining the function in the derived classes TH1F,etc. Rene Brun
