Hi, If you use TH1::Fit you can use the "+" option to add the newly fitted function to the histogram list of functions. (see doc of TH1::Fit) If you do not use TH1::Fit, do: h->GetListOfFunctions()->Add(func); I do not see anything ugly with this solution. Adding a new member function to TF1 is certainly possible, but I would be very reluctant to add yet one more function to an already large interface.
