Well, however you answered my question. Thank you for that. GetMinimum, GetMaximum doesnt work in my program, but probably it doesnt for other reasons. (For example GetMaximum returned 72 , where xmax is 15; therefore I thought GetMaximum() is not what I think it is; but now I will have a close look) and instead of h->GetXaxis()->GetXmin(), Xmax, Nbins, etc I looked for something like h->GetXmin() - and couldnt find it.

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()....
