[ncl-talk] NCL plot: Three output files

[Rick Brownrigg]

Hi Lara,

Do you have these resources set:

  res at gsnDraw = False
  res at gsnFrame = False

These are True by default; setting them to False prevents the plots from
being drawn immediately, allowing one to then call the overlay procedure,
and then explicitly draw and frame.
