I created a TSpline3 using a preexisting histogram. Is there a way for me to obtain a fit function from the TSpline3 that was created?

@couet can you help here please?

Thank you in advance,
Oksana.

If you want to retrieve the parameters of the TSpline3, it seems (Looking at the doc) that GetCoeff and GetKnot are the methods you are looking for.
