[gradsusr] dotted area on map

[Nikola]

Hello Grads users!

 

I am trying to draw a dotted area on a map in grads, to show the area in
which my calculated (shaded) anomalies are significantly different from
zero.

 

I found an 7 year old topic refering to that it cannot be done except
without a certain "draw polyf" function. I wonder is their possibly another
solution that came up in the last years?

 

Thank you in advance, for any help!

 

Nikola
