[ncl-talk] zoom bug with Area Fill?

[Mary Haley]

Hi Kristina,

Thanks for providing a script and data. I'll have a look shortly.

One possible work-around for the raster contours is to set:

res at cnRasterSmoothingOn = True

Sometimes this gets you the same results as AreaFill.  It just depends on
how dense your grid is.
