Hi Folks,
I am seeing some very odd behaviour when I try to re-bin a histogram with variable bin widths.
When I do the following (see code below) I get the attached output.
I would have expected the second bin in the re-binned histogram to have 5 entries instead of 2. Am I doing something wrong?
Cheers
Andrew

h2->SetLineColor(kBlue);
h2->Draw("same");
