[vtkusers] Easy vtkPlaneSource coloring question

I'm trying to produce a 2x3 array of colored rectangles.

scalars = vtkDoubleArray()
for i in range(0,6):
plane = vtkPlaneSource()
[The rest is standard mapper, renderwindow, renderer stuff]

Instead of the hoped-for 2x3 array of colored rectangles, I get a 1x2 
array, colored according to just the first two of my scalar values.  
That's with the mapper set to "flat" interpolation.  If I set the mapper 
to Gouraud interpolation, I can see the full range of scalar values.

Why is this, and how can I see all my scalar values without going to 
Goraud interpolation?
