to clean the interpolation of neighboring areas

[Isilda da Cunha Menezes]

Thank you vihang, what I wanted to say in my mail is that I just want to
have a plot with the data  in shaded inside of Portugal and not in the
neighboring areas as it appears me in the plot, with shaded in Spain and
in Atlantic ocean due to the interpolation that the grads does. Is the
command mask that indicates me that I should use?

The data that I use in the plot are station data of Portugal region
