Dear colleagues,
  As a new hand using Ferret, I have a question. I want to draw a curved arrow over a current filed to indicate the circulation is clockwise or anti-clockwise. Just like the blue curved arrow in the figure in the attached pdf file. How to achieve this? Can a simple command work? 
Thank you in advance.
