Just a very silly question:
how can i sum parts of 2 1-dim (TH1I) histogramms, which themselves have different axis limits and different number of bins?
Rebin seems to give the right binning, but i dont know how to change the axis ranges.
TAxis *xaxis = hTest->GetXaxis();
seems just to shift the histogramm, which is definetly not what i want!
I want to sum just the parts of both histogramms which lie in the range from
xmin = 100
to xmax = 2000!
Thanks for your answer!
