[gradsusr] How to display contour VS for different time periods

[MD ABDUS SATTAR]

Dear Team
I am a new user of GrADS. I would like to display mean zero 200-850-hPa
vertical shear contour in April for each year during 1983-1992 (prepared
file in attached). I can display these by overwriting, but I cannot label
these. I mean I would like to show which line indicates for which year.


Could you please help me how can I label or display such kind of graph? I
am using monthly mean NCEP reanalysis II data.

I look forward to your message

Best regards
Abdus
