[Paraview] Scalars attribute for multiple set of scalar data

[Kent Eschenberg]

Your second case below worked for me. That is, it seems that "Scalars" is 
required. I could color your 2D square by either scalar.

One warning: in the CVS version of 3.3 a new "Representation" is used by 
default that is named "Slice". I don't know what this does but the result looks 
wrong. Switch it to "Surface" and it looks right.

I also used "Contour" to draw contour lines for either variable. If you wanted 
to see contours from both variables at the same time just use two instances of 
Contour and select different variables.

Let us know if you get it to work. And mention your version of PV and OS.
