Hello All,
I am trying to fit a gaussian to a histogram and write the histogram canvas to a file.
histy->Draw();
c1->SaveAs("y.png");
How do I suppress the following information:
Many thanks.
Karthik.

Hi Karthik,
You can use gErrorIgnoreLevel. For example:
Int_t oldLevel = gErrorIgnoreLevel;
histy->Draw();
gErrorIgnoreLevel = kWarning;
c1->SaveAs("y.png");
gErrorIgnoreLevel = oldLevel;
The levels are defined as (in TError.h):
const Int_t kUnset = -1;
const Int_t kPrint = 0;
const Int_t kInfo = 1000;
const Int_t kWarning = 2000;
const Int_t kError = 3000;
const Int_t kBreak = 4000;
const Int_t kSysError = 5000;
const Int_t kFatal = 6000;
Cheers, Bertrand.
