Re: [ROOT] how to get stats printed when using Minuit?

Hi Rene,

I am using the the example "Fitting in general using the class
TMinuit" line for line (expect the function func which is my own
fitting algorithm) from http://root.cern.ch/root/HowtoFit.html. When I
plot the histogram though, no fit information is displayed. I have
used SetOptFit(1) and even used SetChiSquare(), SetParameter(),
SetParError(), but still the fit information is missing.

>From what I gather, when a histogram is fitted a TF1 object is created
and associated with that histogram. But using the TMinuit method on
the web page you pointed me to, does not seem to do that. Am I missing
something?
