  • Subject: [IDV #VSR-922462]: varying contour interval in color-shaded plot
  • Date: Wed, 16 Jan 2013 10:44:58 -0700
Greetings Russ,

I don't think we currently handle multiple intervals when creating colortables,
at least directly. Depending on how many breaks you have in the colorbar, you 
could redo it using 0.5 K breaks, and duplicate colors over two breaks at the 
upper end.

That said, have you checked out the color tables available through the plugin 
manger?
To enable those plugin's, go to "Tools -> Plugin Manager" and look under the
"Color Tables" entries. For example, you can enable GEMPAK, McIDAS, CIMMS, and
see if any of those tables meet your needs (it looks like some of those may do 
what
you are looking to do).

Cheers,

Sean
