I would like to know if there is a way to change the default SetOptStat value definitively. To give a bit of context, I am looking at many histograms using TBrowser and everytime I switch from one histogram to another, the SetOptStat value gets back to 111.
So far I have tried using
gStyle->SetOptStat(111111);
before initializing my histograms in the code which creates them.
As @bellenot said you might los need to add gROOT->ForceStyle() in your rootlogon.C in case you want to impose the style value to histograms read from a ROOT file and having their own OptStat.
