Re: fit option

Hi,

The TStyle doc says:

// The type of information about fit parameters printed in the histogram
// statistics box can be selected via the parameter mode.
//  The parameter mode can be = pcev  (default = 0111)
//    v = 1;  print name/values of parameters
//    e = 1;  print errors (if e=1, v must be 1)
//    c = 1;  print Chisquare/Number of degrees of freedom
//    p = 1;  print Probability
//  Example: gStyle->SetOptFit(1011);
//           print fit probability, parameter names/values and errors.
//    When "v"=1 is specified, only the non-fixed parameters are shown.
//    When "v"=2 all parameters are shown.
// see also SetOptStat below.

Reading my guess would be that you get only the parameter using:

gStyle->SetOptFit(1)

But you get also Chi/ndf and Errors.
Playing a bit with the option I found you get what you want with:

gStyle->SetOptFit(2)

I will check why the obvious way does not work as explained in the doc.

Cheers, Olivier
