[Paraview] [EXTERNAL] Re: FW: Paraview Legend/Colorbar Question

[Scott, W Alan]

Thanks.  My best idea was to create three filters – clip by scalar for data below the acceptable minimum (solid color), another for above the accepted maximum (solid color), and third within range (discrete colors).  Hacky, and the outside range colors won’t show on the color legend, but it should work.

Out-of-range colors are not supported yet. For non-discrete colors, you can hack it by adding extra control points above and below the region of interest, but that's only a hack and not available for categorical/discrete colors.

A question from one of my users.  Anyone have any ideas?  I know how to solve the 5 discrete color question, but the out of range one stumps me.  (This bug was written up as bug 6657).

Thanks,

I remember we had some discussion a while back about creating legends and wanted to follow-up with you. Is there a way for me to reproduce a legend like the one I’m attaching here?

Ideally, I’d like to use the default color scheme (with 5 discrete colors) but then also add magenta and cyan to highlight data that is outside of a certain range. Let’s say I have information to color in the default scheme from 1 to 10, but I want everything below 1 to be cyan and above 10 to be magenta. Can I explicitly tell Paraview to do that? If so, how might that be done in the most recent version?
