[ncl-talk] sub: Polyline using the netcdf mask file

[dale zuri]

Hi NCL user,
I have been trying to add a polyline to the map, but ended up drawing
nothing. I have a mask netcdf with numbers ranging from 0-19.

Mask = where(masktracer.eq.j, 1, 0)

I would like to draw a polyline wherever the Mask is equal to 1. I would
appreciate any recommendation to help.



Thanks

Dale
