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]);
   }

}
