Re: Anomalous White Space in Contour Plot

Kevin,

This sounds like a bug we fixed for version 5.2.0.

If you want me to verify this before you download and install 5.2.0,
then
could you provide me with your script and data offline?

See:

http://www.ncl.ucar.edu/report_bug.shtml

for information on ftping the files to us.

Thanks,

--Mary
