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()....
