[Paraview] Coloring isocontour by the coordinates outputted from a Transform filter and some other questions

[Shuhao Wu]

Hello all,

Is there a way to color an isocontour via the coordinates outputted from 
a Transform filter? I'm using the Transform filter to "normalize" my 
coordinate systems and I want to display the isocontour colored by the 
normalized Y coordinates. Do I have to create yet another Calculator 
filter to recalculate the normalized Y value that is already calculated 
by the Transform filter?

Also: is there a way to turn off one axis on the axis grid (so turn off 
the Y axis display and leave only X and Z)? What about changing the 
interval on the axis itself (instead of incrementing by 100 as it 
chooses, increment by 250).

I'm pretty new to Paraview (coming from Tecplot). Please bear with me as 
I likely will have more question.

Thanks,
Shuhao
