Hi rooters,

I have a very naive question : i have a TH1D histo which has 250001 bins from -0.5 to 250000.5 keV. I would like to rebin it in order to get the same histo from -0.5 to 250.5 MeV. I tried to use the rebin method but it does not work and moreover i do not understand what the variable called ngroups ?? Is someone has an idea ??
Cheers,
