[ncl-talk] gsn_csm_contour, blank plot

[Rick Brownrigg]

Hi,

After looking carefully at your script and the output you sent, I can not
tell what might be causing a blank plot. If you are able and willing to
send your data, I could try further testing. You can email it directly to
me, or if its 10'sMB, send it to our ftp site.

Rick

*You can ftp larger datasets and files to:*

ftp ftp.cgd.ucar.edu
anonymous
<use your email address for the password>
cd incoming
put ...
put ...
.
.
.
quit

Note that for security reasons, you cannot list the contents of this
directory, and neither can we. We need to know the *exact* names of the
files in order to retrieve them.
