For example if you have a TGraph *gr with 20 points, you can do gr.DrawGraph(15,&gr->GetX()[4],&gr->GetY()[4],"alp"); Rene Brun On Wed, 15 May 2002, Elena Vataga wrote: > > > > Hello, rooters! > > I have a set of TGraphs made with: > TGraph* gr1[Wed] = new TGraph(36,z,punt1); > > Is there a way to Draw TGraph using only part of those vectors? > (like it was in paw - for example use 10 points starting from 3) > > > Sorry, failed to find it in documentation. > > Thank you in advance, > Elena >
