Hello,
I am trying to make a contour plot using TMinuit. After the function minimization, I use the following commande:
where gMinuit is my TMinuit object, and par1 and par2 are the parameters for which I draw the contour plot. However, I always get at most 4 points in the contour plot (when it doesn’t fail), with the warning:
MINUIT WARNING IN MNContour
============== Cannot find midpoint, try closer.
Warning in <TMinuit::Contour>: Returning a TGraph with 4 points only
What should I do to get a reasonable number of points?
Thank you in advance
