You can write a graph as all TObjects to ROOT file. Modify $ROOTSYS/tutorials/graph.C as follows: gr->GetHistogram()->SetXTitle("X title"); gr->GetHistogram()->SetYTitle("Y title"); // write TGraph to file TFile f("graph.root","RECREATE"); gr->Write(); f.Close(); } Then open the file with the TBrowser, get the list of contents, double click on Graph;1 and you should see the graph.
