[ncl-talk] Label Bar Label Missing

Wed Apr 19 00:43:47 MDT 2017

Hi:

I was able to make the change suggested, but when I read in the data and
process it first (instead of starting with a ready made file), the first
panel is larger than the rest.

I assume this is another "bug" in the WRF settings...

This doesn't happen when I supply the output as a ready to read file.
