Hi
I'm having some problems with this simple canvas:

-----------------------------------------------------------------------------
TH1F* e_Gain;
e_Gain = new TH1F(name,title,NbApv,0,NbApv);
 TCanvas* c1 = new TCanvas("MyCanv","GainComparing",200,10,1100,1100);
    
    //c1->Update();
    //c1->SetGrid();



    //e_Gain->SetMarkerStyle(20);
    //e_Gain->SetMarkerColor(6);
    //e_Gain->SetMarkerSize(1.1);
    //e_Gain->SetXTitle("Apv nb.");

    //e_Gain->Fit("pol1","Q");
    //pol1->SetLineColor(3.5);
   
    e_Gain->Draw("e0");

    
    //delete MyCanv;
  
-----------------------------------------------------------------------
it seemed to work but when I run it root gives me this:

 Warning in <TCanvas::ResizePad>: MyCanv height changed from 0 to 10

 root [5] Warning in <TCanvas::ResizePad>: MyCanv height changed from 0 to  
 10

and it leaves the canvas empty.

Thanks in advance
