[ncl-talk] no value at the equator and additional line using gsn_add_polygon

[刘振]

Dear Sir/Madam:


  Attached please find my script and figures. I got three questions about the figures.
  Figure 1: why there is a white line over the equator? How to remove it?
  Figure 2: For All_F in red shading line, why there is a addition red line connect from the beginning to the end. I found it seems to be a problem with gsn_add_polygon function I used. How to remove this line? 
  The third question is how can I add more space between legend labels vertically (i.e. All_F and Aero) in Figure 2?
  Look forward to your replies. Thanks.


Best regards,
zhen
