[ncl-talk] Error while handling multiple WRF output files

The issue is that your left plots have a title on the Y axis, while your
middle and right plots do not. gsn_panel assumes all plots are the same
size, and uses the first plot in the list to determine the scale factor for
all the rest. Since the left plots are different in size, the scale factor
applied to these plots ends up being different than the scale factor
applied to the right plots.
The key here is to set the special gsnPanelScalePlotIndex to the index of
one of the middle plots, so it uses one of these for the scaling factor.
Your middle plots are indexes 1, 3, or 5, so:
pres at gsnPanelScalePlotIndex = 1 ; base resizing on plot1 (middle plot)
I've added dummy data to your gsn_function_try.ncl script, and cleaned it
up for you. I had to leave a little bit of a margin on the left side of the
panels, so the Y axis strings didn't get cut off.
If you don't want all that space between the X axis of each plot, you can
set the gsnPanelTop / gsnPanelBottom resources as desired to squish them
together. I also set the gsnPanelYWhiteSpacePercent to 0 to force them
closer.
See attached.
