Handling paramon in roofit

Hi

While trying to display parameter used in the fit in roofit with the ‘paramon’ method, the display box chooses its default setting. I wonder how to handle the Fonts and its size and what(what not) to display in that box. I also like to display chi2 of the fit in the box, currently i can print it out by
cout << "chi^2 = " << xframe->chiSquare() << endl;
but i would like to display it along with the parameters.

Thanks in advance.

I am not sure if ROOFIT uses the standard PaveStats box to display the stats. If yes use the SetOptFit used many times in the examples here:
