[ncl-talk] White streaks on plot

[Michael Notaro]

Never mind.  Apparently the plot is fine.  It is an issue

of the way that ghostscript is displaying it on NASA Discover.

Subject: White streaks on plot


Please see the attached plot.  Does anyone know why I am getting white

streaks across my plot and how to get rid of them?  I am using NCL 6.4.0.

Thanks, Michael
