What about something like this: 

  root[0] TNtuple* n = new TNtuple("N", "N", "x:y")
  root[1] TRandom* r = new TRandom
  root[2] for (Int_t i = 0; i < 10000; i++) 
            n->Fill(r->Gaus(5, 2), r->Gaus(10, 3))
  root[3] n->Draw("x:y")
  root[4] htemp->GetXaxis()->SetRangeUser(-10, 30)
  root[5] htemp->GetYaxis()->SetRangeUser(-10, 30)
  root[6] c1->Modified()
  root[7] c1->Update()

Yours,
