[ROOT] likelihood contour plot

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
