Why are you doing: pl->PaintLatex(pl->GetX()-.5,pl->GetY()-.05,angle,size,text); instead of: pl->PaintLatex(pl->GetX(),pl->GetY(),angle,size,text); Rene Brun On Tue, 5 Nov 2002, Ed Oltman wrote: > Hello, > The following script illustrates the effect I observe... > > { > gROOT->Reset(); > TF1 *pf = new TF1("pf","sin(x)/x",0.,10.); > pf->Draw(); > TLatex *pl = new TLatex(6.,.5,"A^{b}"); > pl->Draw(); > double angle = pl->GetTextAngle(); > double size = pl->GetTextSize(); > char *text = pl->GetTitle(); > > > // now, some PaintLatex calls and the object's position changes.. > for(int i=1;i<10;i++) > { > pl->PaintLatex(pl->GetX()-.5,pl->GetY()-.05,angle,size,text); > printf("%f %f\n",pl->GetX(),pl->GetY()); > gPad->GetCanvas()->Update(); > gSystem->Sleep(100); > } > } > > > -----Original Message----- > > From: Rene Brun [mailto:brun@pcbrun.cern.ch] > > Sent: Tuesday, November 05, 2002 12:40 AM > > To: Ed Oltman > > Cc: Roottalk@Pcroot.
