[ncl-talk] uneven colorbar

[Mary Haley]

You can set:

res at cnLevelSelectionMode = "ExplicitLevels"
res at cnLevels = (/-10,-8,-6,-4,-2,0,2,4/)

"cnLevels" can be any spacing of values that you want. They don't have to
be equally spaced, but they do have to be increasing.

If you need to match certain levels to certain colors in a color map, then
you may want to see example "conLev_4.ncl" at:
