You can't with the standard module but you can tweak the module if you
are using a recent enough VTK. I guess 4.2 or 4.4 will do. You need
to select the scalar you want to color with in the data file and then
use the contour filters SetInputArrayToProcess(...) method to set the
specific data array you want to contour with. Then your coloring will
be based on the input scalars and the contouring with the one you
pick. I haven't tried it so you should use this as a guideline and
experiment to see what works best for you.
