How do you integrate over a histogram? Like splitting up histogram into sections with each section in a bin? this is what I have.
TH1D *h1=new TH1D(“h1”,”Rings”,400,0,1300)
h1->Integral(600,800)

I’m not sure I understand your question. What you do seems correct, see the documentation of TH1D::Integral (Int_t binx1, binx2, *option="")
@bellenot mentioned - what you are doing is correct.
Just in case, you are putting ;
after
h1->Integral(600,800)
then remove it and try!
