[gradsusr] WAFS GRIB2: Cannot contour grid - all undefined values

Sun Dec 15 18:21:55 EST 2013

Another thought... try plotting again without setting the set lat / set lon
domain constraint and see if it will plot the full domain. If it does, then
the issue is either with the coordinates you're trying to zoom to (outside
of the domain) or perhaps something with the projection... IE polar stereo
won't let you do that in that projection. I'm not familiar with this
dataset so I dont know what the projection is.
