Dear Couet,

Thanks for suggestion.

I tried it. And it is working but then I am not able to view the data points. It looks likes

TimeResolution_wrt_EDrift.png698×474 10.6 KB

and if I remove the fillColor line then it looks like

The patch of code that I used is:

   TPad *p = new TPad("p","p",0.,0.,1.,1.); p->SetFillStyle(0); p->Draw("same"); p->cd();
   TBox *b = new TBox(0.2,0.15,0.7,0.47);
   //b->SetFillColor(2);
   b->SetLineColor(2);
   b->SetLineWidth(8.);
   b->Draw("same");

If I don’t use TPad then I am not able to see any box.

with regards,
Ram
