Default Paraview: How to plot over a circle?

Dear Foamers,

I want to analyse the velocity profile of a turbomachine. Therefore I want to plot the velocity over a circle. (radius, sampling points)
But the problem is, that paraview only offers plotting over a line or a sphere!
In the end my aim is comparing plotted velocity to CFXpost, "surface of Revolution".

please help me!
Best regards,
chris

It is possible. Apply the plane filter. Then use the "Plot Over Intersection Curve"-filter. In that select the sphere. What the intersecting curve between a plane and a sphere is (if they're properly placed) is left as an exercise to the reader.

Thanks a lot you for your help!
It works, but not in the way I exactly wanted to. What I get on intersection is a octagon, not a circle.
So I tried it the other way: First I take a sphere source. There I chose a really high theta resolution, so I got a very good approach to a circle. Next I take the "plot on intersection curves" and took the plane:
But Paraview don't want to plot not one of the physical quantities. (it offers only useless things like "normals" or "points"). paraview makes me really depressed.

Regards, Chris
