[Paraview] Plot on a Contour surface

[Jacques Papper]

One useful thing I have been doing is to use the calculator before doing a
2D plot and creating a varible "x" = x_coord so that I can plot against a
geometric coordinate instead of an int. It's weird that I have to do this
and can not access the x variable directly ...
