Hi Luc,
You have a mismatch in your print statement. What you want to do
is probably something like:
for(j=0;j<nbins;j++) {
printf("bin[%d] = contenu[%d]=%g\n",j,j,h1->GetBinContent(j));
}
Your second point about number of channels. TH1::Print("all") prints
all channels, including bin=0 (underflow bin) and bin =N+1 (overflow)
