Hi Robert,
gStyle->SetOptStat or gStyle->SetOptFit can be used to change the default
option that will be used to create the TPaveStats object when painting
a TH1 or a TGraph. Once the TPaveStats object is created, it is added
to the histogram list of functions. Next time the TH1 is redrawn,
the existing TPaveStats object is drawn with its current properties that
you can modify via TPaveStats::SetOptStat and SetOptFit (via the context
menu or C++). This feature is new in 3.03/09 and it allows to easily keep
a TPaveStats for more than one histogram displayed in the pad. See the
3.03/09 release notes at section "New Options in THistPainter" at:
http://root.cern.ch/root/htmldoc/examples/Version303.news.html
or at:
http://root.cern.ch/root/htmldoc/THistPainter.html#THistPainter:Paint
To access the "stats" box, do:
TPaveStats *st =
(TPaveStats*)h->GetListOfFunctions()->FindObject("stats");
h->SetOptStat(11); //for example
