Re: Order of legends

Saji,

I had to double-check, but there's no way to reverse the automatic
legend.

You can, of course, create your own legend with gsn_legend_ndc or
gsn_create_legend. See examples 6 and 8 at:

   http://www.ncl.ucar.edu/Applications/legend.shtml

Meanwhile, we're looking into how easy it would be to add the
capability to reverse an automatic legend. Seems like a reasonable
thing to want to do!
