RE: Stats box in a TMultiGraph and significant digits

Hi,

Answer to your question 1:

Multigraphs are collections of TGraph plotted all together so common minimum and maximum can be computed. TGraph doesn't have statistics (only TH1,2,3 have). So you cannot get statistics box on a multigraph. I am not sure how you would like to convert a Multigraph to a TH2... May be send a running little example to this list describing a bit more your problem.

Cheers, Olivier

Hi,
the answer to your second question is:

gStyle->SetStatFormat(const char* format = "6.4g")

Cheers,
