[ncl-talk] problem with creating an rgb colormap

[Cynthia Hays]

Hi Rick,

I think  I just needed to send it to you to make me think differently.  I needed to change
res at cnLevels             = ispan(2,31,1)
res at lbLabelStrings       = ispan(1,31,1)

to

res at cnLevels             = ispan(2,33,1)
res at lbLabelStrings       = ispan(1,33,1)

I forgot about changing the number of colors in the colormap.  It seems to work fine now.

Thanks

Cindy

Hi Cynthia,
I'm getting a NetCDF4 error on that wrffile, so I can't see the plots.  I see in your script you draw the merged colormap -- does it look correct to you?
I'll look into why I'm seeing an error.

Hi,

I’m trying to plot landuse  from a WRF file using my own defined colormap (landuse.rgb).    I’ve defined when water is the landuse that the color is blue  and urban should be red but I’m not getting those colors.  This is an old script that I had used successfully with a different landuse.rgb file for different WRF landuse categories  so I thought I could just edit the landuse.rgb file to reflect the new landuse categories and colors and it would work.  I’ve put the following files  landuse.rgb, domain_d01.ncl and wrfinput_d01 on the ftp site.   I am using ncl version 6.4.0 (I actually tried an older version that the script was first used in and I was getting the same color problems, so I don’t think it is a version problem).

Thanks

Cindy
