Hi,
It looks like when you create a 2d histogram hist, bins in x and y start
at 1.
When you execute the following command :
hist->GetBin(1,1)
the result is not 1 (0 would also be ok) but 19 in my case (TH2F, 16*16
bins).
Yet :
hist->GetBin(0,0) gives 0. But if you try to fill this bin
(hist->SetBinContent(0,1.)) and draw the TH2F, you see that this bin is
out of range....
Does anybody know if it's a bug or if the previous bins are used for
something else ?
Thanks a lot.
Colin
