AW: AW: AW: [Paraview] Combine vect

[Amy Henderson]

I just tried to reproduce this behavior on the ParaView 1.4 release, but I=
=20
did not get the same results you did. After I ran the data through the=20
Calculator filter, it was still being colored by the same scalar array as=20
before, but the array produced as a result of running the filter was a=20
3-component vector array.
