[gradsusr] Cannot able to plot NARR data

[James T. Potemra]

Hi Kalyan,

There are a lot of missing data in your file, so that might be why 
contours/shading doesn't show up.  If you use "set gxout grfill" before 
"d thick" you can see all the valid grid cells. Also note that your 
longitude values are somewhat unconventional and run from -220 -0.4375 
(140E to 0), so make sure your "set lon x1 x1" is within that range.
