[ncl-talk] Regarding annotation

[swati shewale]

about above query, I went through function 'str_get_cols'. I understood it.
Now I want to put single city (Ahmedabad) annotation in my plotting. I am
afraid as am handling wrf file, Can I  accommodate it? please find the
attachment, annotation.txt (contains single city), annotation.ncl (wish to
put all the statements from this file to wrf_annotation.ncl so that It
could reflect Ahmedabad city). kindly provide suggestion.
