Re: drawframe and Stats

Hi Luca,

Do something like:

{

   TFile *f=TFile::Open("hsimple.root");    TTree *ntuple = (TTree*)f->Get("ntuple");    TCanvas *c1 = new TCanvas();
   c1->SetLogy();
   ntuple->Draw("pz:px>>h2(50,-3,3,50,1e-2,20)","","");    TH2 *h2 = (TH2*)gDirectory->Get("h2");    h2->SetMaximum(0);
   h2->Draw("sames");
}
