[gradsusr] how to plot data over a particular region using shape file

[sushant puranik]

Thank you Jennifer for your useful response. My query is slight different.
As I said I have rainfall data over India and I want to plot only for
Maharashtra (whose shape file is with me) state. So how can I plot rainfall
only for Maharashtra state while masking/discarding data over rest of the
country.
