Need a hint - how to automatically draw "H" and "L" into a pressure chart

[Juan Matias Mendez Perez]

Hello Tervehdys,

If you want to draw "H" and "L" automatically, I found the GrADS UDF
called clhilo developed by Mike Fiorino. I sincerelly haven't used it,
but you can explore this solution.

You can get code here:

Good luck,

Matias
