mapping for selected area

Hello users,

Mary was kind enough to provide me a new ncl script that can be used to map
a variable from a CSV file containing data sets of selected coordinates. I
have slightly modified the script to overlay the borders of the region.

Now my requirement is to trim the color shades that lies outside the border
of the region (Bangladesh). I am attaching the ncl code, CSV file and pdf
file generated.

I request the users to help me.
