Number of histogram entries within a range

ROOT

Hello,

Is it possible to get the number of entries in a histogram that has already been created, within a range–say, get the number of bins between 2.4 and 5?

Best,
Danny

If your histogram is filled with weights=1, you can call
TH1::Integral(bin1,bin2);
otherwise you should use a TProfile and use the function TProfile::GetBinEntries(bin)
