Hi Rashed:
Many thanks for your suggestion. I really appreciate you taking an interest
in my very pesky problem! Following your idea helped removed the "big" plot
in the second row of the panel, but it now shifted the label bar for the
second row to the third row. If you compare test.png and
totPREC.dec2015.png, then you will see that the bottom row is the same as
that for the second row, which is not what I expected (see
totPREC.dec2015.png where the panels for the top row are the same and not
centered.)
Great idea though. At this time, I'd tried anything.Thanks.
Laura
