[ncl-talk] help with plotting shapefile polygons

Hi Dave,
I was able to successfully run the diagnostic test code with the original
shapefile_utils.ncl and Rick's deprojected .shp, and got the same PNG image
you did.
I also ran my code using Rick's deprojected .shp, and was able to produce
the same PNG image using either the original or replacement
shapefile_utils.ncl.
And, I tried your most recent method testing the
shapefile_funcs.reversed.temporary.ncl, the replacement shapefile_utils.ncl
and the original (not deprojected) .shp, and was able to produce your PNG
image. However, when I put the first two lines into my code, the county
outlines do not appear in the shapefile map.
