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.
Cheers
