Rebin the x-axis, say dividing the whole x-range into 10 bins

[sohail]

am trying rebin in this way but i know one command of rebing e.g. h->Rebin(10); but i don’t know is it right for this or not how i can manuplate it?

Try:

h->Rebin(h->GetNbinsX() / 10);

And what is your problem with this plot?

BTW. Before rebinning, you should probably execute:

if (h->GetSumw2N() == 0) h->Sumw2(kTRUE);
