[ncl-talk] "RasterFill" not plotting field

[Mary Haley]

Hi Ryan,

You might try adding this resource, to have the raster plot generated a
slightly different way:

res at trGridType = "TriangularMesh"

Still, I'm curious about why the plot is not showing up with raster fill.
Is it sparse data?  It would be good to get the script and data if
possible, so we can make sure it's not a bug.

Thanks,

--Mary
