1D axisymmetrical profil on a slice

Hello, I’m trying to do an extraction of the profil on differents slices (Not a plot over line).
I have my Radius and my cylindrical velocity component.
The Idea is to do a mean of velocity for different radius on the same slice in order to get my axisymmetrical profile.
I can do this with other software but I just started to work with paraview.

Can anyone help or do you have an ideas ?
