[ncl-talk] Adding a Legend to Shapefile Plot

[Carlos J. Valle-Diaz]

Hi Rick,

Related to your 3rd suggestion: when I ran the script before I
incorportated the codes to create the legend, I did not have a mismatch
error. The script generated the colored markers with the black circles as
you showed me in a previous conversation. Why would it present a mismatch
error after adding the codes creating the legend?
