[ncl-talk] resources issue

[Rashed Mahmood]

I am not sure what you are trying to achieve here. Did you try to test
this? What does your plot look like?
Since I do not have your data file so I used dummy data to test the plot
using your resources. See attached plot and the script, there is no problem
with triangle edges.
