Hi emily,
This is explained in:
http://root.cern.ch/root/htmldoc/THistPainter.html#THistPainter:Paint
look at section "Statistics Display"
When the histogram is drawn, a TPaveStats object is created and added
to the list of functions of the histogram. If a TPaveStats object already
exists in the histogram list of functions, the existing object is just
updated with the current histogram parameters.
With the option "same", the statistic box is not redrawn.
With the option "sames", the statistic box is drawn. If it hiddes
the previous statistics box, you can change its position
with these lines (if h is the pointer to the histogram):
Root > TPaveStats *st =
(TPaveStats*)h->GetListOfFunctions()->FindObject("stats")
Root > st->SetX1NDC(newx1); //new x start position
Root > st->SetX2NDC(newx2); //new x end position
To change the type of information for an histogram with an existing TPaveStats
you should do: st->SetOptStat(mode) where mode has the same meaning than
when calling gStyle->SetOptStat(mode) (see above).
