[Paraview] Hiding Cells

[Brian C. Panneton (CONTR)]

I have a reader plugin that has a group of VTK_LINES that exist between 
points. The color of these lines represent statistical data at a 
specific time. Sometimes there is no data for the line, thus the scalar 
= 0. When this occurs, I would like to hide the line from sight. Is 
there a way to do this, or will I need to add and remove the cell for 
each time step?

Thanks,
Brian Panneton
