3D fitting

Hello All,

It is not clear to me how one can fit multidimensional function in ROOT? Meaning 3-more dimensions. It seems like the fitting function can be defined very easily as multidimensional but I cannot create TGraph or TH objects with dimensionality > 2. Is there another way how to do the fitting?


Currently only TH3/TF3 combinations are possible.
You can use TMinuit directly for a multi-dim fit problem.
