[gradsusr] Drawing something (line, point,...) over the map

[T. haghroosta]

Dear All,
 
I have to repeat my question, Is it possible to draw a path with specific coordinates? For example I would like to show the position or the track (moving path) of a typhoon on a map. Is it possible to put some points (with specific coordinates) or lines on a map seperate from contours?
 
Regards,
