[ncl-talk] same data can get different dots when they are plotted in top or bottom

[Tao Zhang]

Hi,

When I use NCL to plot significance area, the same data can get 
different dots (see Northern Montana for example)

when they are plotted in top or bottom.

  see below for key sentences and attached plot.
  Any comments?

  Thanks,

  Tao
