Hi All, I've fitted a TH1F histogram with the ML method using his->Fit(FunName, "LRB0"). The macro code was modified from langaus.C in $ROOTSYS/tutorials/ and I defined 3 parameters. I know how to get the maximum likelihood value at the best fit point, but I wonder if I can plot the likelihood function as function of one parameter or contour plots for two parameters. Is this implemented in ROOT? Or any suggestions? Thank you. Regards, Tingjun
