[ncl-talk] Blank graphics in ncl

[Zilore Mumba]

Rick,
I have attached to this mail, 1) the script which produces the graphics, 2)
the two png's by the same script but on different platforms and 3) the
.hluresfile which is on both machines. In the attached .hluresfile I have
removed the dot at the beginning of the file name, but the dot is there in
the running copy.
Thanks for your time.
