Bernard,
Why to do things complicated when they can be simple?
In your case, you are calling the Fit fonction. By default this fonction
draws the results of the fit and creates the TPaveStats.
Then you set the style options.
Then you redraw the histogram.
Simply do:
{
gStyle->SetOptStat(10000001); gStyle->SetOptFit(111);
h_jets_emf.Fit("gaus","","pe",0.3,0.9);
}
In version 3.10/01, calling gStyle->SetOptFit or SetOptStat redraws
automatically the stats box with the current parameters.
