Hi Sujata,
I have not been able to mask-out or blank a particular boundary (country or state) so that the contour or shading does not spill out of the boundary country boundary.
I had earlier posted this query to Grads Users forum but did not get a response. I hope this time there will be a response from the Grads Gurus.

Hi Zablone,
I am attaching my model domain. I want to plot certain model variables in a particular state (i.e ORISSA) as mentioned in the plot. Can I plot on a particular state (like Orissa) and mask the other area.
regards,
Sujata

The trick I normally use so that I get a blank map is to set cmin a value higher than the maximum value of the variable (there could be a better way of doing this, I hope somebody will point it out). For example I set cmin 10 before diplaying pr variable in model.ctl.
