Hi,

    Is it possible to make a 3D graph on ROOT and then fit it with a user defined function?

    I have a set of points (x,y,z) that belong to a spherical surface and I would like to place them on a graph
(like in the 2D case) and then fit a sphere through them to get the center and the radius.

    I can plot the points in a 3D scatter plot (using a histogram - TH3F), but then I can't fit the histogram using a function

    Is there anything available for this on ROOT?

    Thanks!

Stelios.
