[gradsusr] maskout problem

[Mandal Raju]

 Hi,

 I have a plot of temperature anomaly over the region: lat 0 to 40N
                                                       lon 60E to 100E

 But I want to show the values only over Indian sub-continent. So, can anybody help me how to maskout those outside region from the actual plot?



 Thanks & Regards....
