Missing data

["Rolando S. Balotro" <rbalotro@xxxxxxxxxxxxxxx>]

Hello Ferreters

In plotting my results I found that a lot of white
areas that indicates missing values are drawn.

However when i use other plotting package (eg. NCARG)
such white areas are not present at all.

I am attaching the gif figure as an example.
I suspect Ferret treats some data points (especially)
near the coast as missing data. Is there a way to avoid
this?

Thanks in advance
