[ncl-talk] cnFillPalette

[Laura Fowler]

Hello:
I am trying to make a panel plot using two separate color maps, as in
color_9_new.ncl. Of course, I am not able to get what I think I would get
as the last two colors of my color map are white and black when using
cnFillPalette.

My first color map is as follows:

*cheyenne6* laura/colormaps> more myRadar2.rgb

ncolors = 13

#  r    g    b

# 181  202  255   # super light blue

  223  255  249   # super light blue

    0  157  255   # light.blue

    0  255  255   # cyan

    8  175   20   # dark.green

    0  255    0   # green

  255  214    0   # yellow

  255  152    0   # light.orange

  255    0    0   # red

  165   42   42   # dark read

  240   80  240   # pink

  121   51  160   # light.violet

  195  163  212   # violet

  255  255  255   # white


When using

res at cnFillPalette = "myRadar2", I get the following warning:


warning:ContourPlotSetValues: color index (13) exceeds size of palette,
defaulting to foreground color for entry (11)

warning:ContourPlotSetValues: color index (14) exceeds size of palette,
defaulting to foreground color for entry (12)

warning:ContourPlotSetValues: color index (14) exceeds size of palette,

which I guess makes sense since cnFillPalette will have two fewer elements,
according to the documentation. What do I need to do to make this work. Do
I need to add the ForegroundColor and BackgroundColor to the color map? How
to do this? (It works perfectly well using gsn_define_colormap).



I also tried to use res at cnSpanFillPalette = False (or True) but that did
not do anything (What is it supposed to do anyway).


Many thanks for your help,

Laura
