Hi,

As for the mail I sent before, I have a trouble.

  TH1F *hnew = new TH1F("hnew","hnew",100,0,1000);

  Int_t  N_entry = tree->GetEntries();
  Float_t ThresholdEntry = N_entry*0.005;
  Int_t i;
  Int_t number=0;
  for(i=100,number<ThresholdEntry,i++){
  tree->Draw("ch0 >> hnew", "ch0 > i" );
  number = hnew->GetEntries();
  }

Error message :  Unknown name : "i"
What should I do to compare Leaf with a variable ?
