[ncl-talk] Avoiding overwritten gsnCenterString

[Adam Phillips]

You could put a carriage return in the gsnCenterString for plot2 and put
two carriage returns in your plot3.
https://www.ncl.ucar.edu/Document/Language/carriage.shtml

This will result in the CenterString for plot3 being on top, the
CenterString for plot2 being in the middle, and the CenterString for
plot(2) being on the bottom.
Hope that helps!
Adam
