[Paraview] Extract Z Component of a Normal or Vector

[Michael Jackson]

I have normals precomputed for a triangle based surface mesh. I have had a request to color the mesh by the Z component of the Normals. Is there a way to use the calculator or something to extract just the Z component of the normals to a result array that I can then use for coloring?

Thanks
