Hi -,
Thanks for your reply. But for the second question, if you look at the Figure 2 in detail, I want to shading the one standard deviation of the red line. But I want to delete the addition red line from the start point to end point. So the function gsn_add_polyline may not satisfy my requirement. Is there any other solutions? Thanks.
Best regards,
zhen

You mean Greenwich Meridian?
https://www.ncl.ucar.edu/Document/Graphics/Resources/gsn.shtml#gsnAddCyclic
You set this resource to false, therefore NCL did not bridge the gap.
Near the top of your res file:
> res at gsnAddCyclic = False ; data already has cyclic point
> 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.
It's trying to draw a polygon (i.e. a closed shaped), the docs clearly state that if first and last points are not equal then the function will close the shape for you. If you just want a line, then draw a polyline.

Starting point is probably the resource pmLegendHeightF lots of examples of legend layout though.
Documentation, the user guide and google for old ncl-talk emails will go a long way.

Good luck,

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,
