Hello,

I am trying to include fit parameters in the stat box of a histogram (TH1F) that is written to a root file. I have

  gStyle->SetOptStat(1111);
  gStyle->SetOptFit(1111);

in my code so that the stat box will show the specified values (chi squared, etc.) when drawing the histogram. However, when the histogram is written to a root file, the stat box only includes the default values (entries, mean, std dev).

Is there a way to include the fit parameters in the stat box of the histogram that gets written to the file?

Thanks!

I think it’s not that the info is not “included”, but just not shown by default, see the note on SetOptFit; try putting those gStyle options in your rootlogon.C file.
