Note: in this thread, I am talking about v5-28-00-patches as some other software expects it (the problem does not exist in v5-30-00-patches, I don’t have v5-32-00-patches here to test it).
The attached “test file” is also valid for the problem that I reported here: [url]Minuit versus Linear fitter in ROOT v5-30-00-patches
BTW. There seems to exist another problem. When I simply save my graph using “MyGraph->Write();”, the “associated” histogram is not saved. When I then open the ROOT file and try to “MyGraph->Draw(“AL”);”, I get a “segmentation violation” (for the moment, I simply say “MyGraph->SetHistogram(0);’” before saving it).
