Hi Root users, In my attempt to tabulate the number of entries versus Ntuple variable value, i wrote the following code, which is err. could any one suggest, what is wrong with this code. Sincerely, Navneet { gROOT->Reset(); filename ="gamma_5.000_3.5_0_20_5_90_10000_ntp.root"; TFile *r = new TFile(filename); TTree *Tree = (TTree*)r->Get("t1"); Tree.Draw("Trig_Bits>>hist"); Int_t numBins =hist->GetNbinsX(); Double_t binContent[100]; Int_t bin[100]; printf("%s\n\n",filename); printf("Bin: Trig_Bits: Events\n"); for(int i =0; i<numBins;i++) { bin[i] =hist->GetXaxis()->FindBin(i); binContent[i]=hist->GetBinContent(bin[i]); printf(" %d \t %f\n "bin[i],binContent[i]); } }
