>Dear Steve:
>  I'm using some JOSS-generated NOGAPS analysis/forecast grids, and trying

>the color of the barbs to be 0, but that didn't seem to work. Using
>gvect=0 or none yield error messages. The goal for this plot is to have
>the westerly component contoured in one color and the underlying theta
>field contour-filled in another color series. There are lots of levels
>below 900 hPa, and the barbs are very busy. Perhpas I need to keep trying
>to make the barbs Invisible. Another option would be to learn how to
>exclude data so as to have only a few barbs plotted. Thanks for any help
>you can provide.                              John
