[ncl-talk] how to reduce white space

It's kind of complicate how the maximization works.

What's happening in the case of the two sets of panels, is each set of
plots is being maximized to the area you've specified with gsnPanelRight
and gsnPanelLeft.  The setting of 0.1 and 0.5 for the leftmost plots puts
the plots almost right up against the leftmost edge, and ditto for the
right most plots which are up against the rightmost edge and thus there's
not much room for the plots to be maximized before they would run into each
other. The maximization operates on the plots in such a way they maintain
their position relative to the Right and Left settings.

To give the plots a little more room to maximize, you can slightly decrease
the gsnLeft setting for the left plots, and the gsnRightSettings for the
right plots:

  resL at gsnPanelLeft     = 0.09 ; 0.08

  resL at gsnPanelRight    = 0.5
. . .
  resR at gsnPanelLeft     = 0.5
  resR at gsnPanelRight    = 0.91 ; 0.92
