[ncl-talk] A fill pallette question

[Rick Brownrigg]

If I understand to the first question correctly, maybe something like:

cmap = read_colormap_file("NCV_rainbow2")
printVarSummary(cmap)

cmap := cmap(50:, :)
printVarSummary(cmap)

On the second question, there's a small set of conditions as to whether the
palette is spanned vs. whether consecutive values are used; check out
cnSpanFillPalette:

Hope that helps...
