NCL doesn't display my Domain Preview

[j_nava]

I was trying to use the plotgrids.ncl example found on the ncl examples page but I noticed that none of the colors where present on this plot. Therefore I tried reinstalling my version of NCL. Once I finished with the reinstallation, I tried to use this file, but got the following output:

I don't understand why I get this errors, since I only have 3 domains.
I attach my namelist.wps and the plotgrids.ncl file I'm using.

I could use any help with this issue since I'm just starting with NCL.

Thanks in advance!!

Hi,
When you download WPS, you can find th script util/plotgrids_new.ncl. You can simply run this scrip by
ncl util/plotgrids_new.ncl.
Please let me know whether it works.

Hi, when I use this script I get the plot but it doesn't display none of the colors it's supposed to, showing just a plain white plot as seen in the attached picture.

How could I solve this issue, so that the plot is displayed as it's supposed to?

This also happens when I try to plot the geogrid fields, as I don't get the corresponding contours.

Please download NCL scripts from NCL Graphics
You can run these scripts to plot figures using various WRF-related files, e.g., geo_em, met_em, wrfout, etc.
