[ncl-talk] panel_33.ncl

[Laura Fowler]

Hi Mary:

Many thanks for taking the time to rework the script. Using
panel_33_mod.ncl, I was able to modify my script to produce the plot I
needed (see attached totPREC.png and test.ncl in
/gpfs/fs1/scratch/laura/MPASprojects2018/MPAS.cu_shallow/novemberPUBLICATION/precipitation_figs).
I need a little more work to align DEC 2015 and JUN 2016 to their
respective columns).

I further modified test.ncl (test2.ncl in the same directory) to remove one
row from the top panel so that I can have 2 panels of two rows with one
color bar for each panel. I do not understand the logic on how to modify
res at gsnPanelBottom to make this work on a more systematic basic. It seems
like there is a lot of "guessing" in doing this?

Thanks,
Laura
