[ncl-talk] Using vp resources for panelling different sized WRF contour plots

[Mary Haley]

I'm sure there must be a better way to do all of this, but you can try using
pmLabelBarParallelPosF
, which allows you to move the labelbar left or right.  See panel_21.ncl at:
http://www.ncl.ucar.edu/Applications/panel.shtml#ex21

which uses pmLabelBarOrthogonalPosF, but is the same idea.
