Pop-up of the canvas

Please read tips for efficient and successful posting and posting code

_ROOT Version:6.30/4
Platform: Not Provided
_Compiler:

I want a pop-up window by running -
void tree_r(string rootfile)
{
TFile f = new TFile(rootfile.c_str());
TTree t1 =(TTree*) f->Get(“t1”);
t1->Draw(“X1off>>h1(1000,-100,200)”);
}

I use this in main() and compiled it. On running the executable this is showing “Info in TCanvas::MakeDefCanvas: created default TCanvas with name c1” but no canvas is poping out.

Thanks,
