The viewing range for a histogram axis can be set from bin ifirst to ilast using the method TAxis::SetRange(ifirst, ilast). Example (hpxpy is a 2D histogram): { TFile f("hsimple.root"); hpxpy->Draw("colz"); hpxpy->GetYaxis()->SetRange(22,23); hpxpy->GetXaxis()->SetRange(18,19); } Sometimes it is more convenient to set this range using “User’s Coordinates” (axis values) rather than bin numbers. To do that one should use TAxis::SetRangeUser(ufirst, ulast). This method computes the cl…
