Hi Bernd, I do not understand your question. All what you request is already provided by the TH1 class. Assuming TH1* h, you can do h->GetMean() h->GetRMS() h->GetEntries() h->GetMinimum(minval); //Return minimum value greater than minval of bins in the range h->GetMaximum(maxval); //Return maximum value smaller than maxval of bins in the range h->GetXaxis()->GetXmin(), Xmax, Nbins, etc h->GetYaxis()....
