Yes, I know I can do that, but the contour representation is not the
best. In particular, you cannot see the errors on the data points, or
get more than a rough feel for how close the fit and data really are.
To do that, we have to have a 1-d representation in slices, and that
means plotting slices of a TF2.
Probably not a simple thing to add to ROOT, but as I say, I think it is
potentially very valuable, especially if it can be generalized to TF3
and even higher -ary functions.
