Re: streamline density

Dear Longtao,

Can you be more specific about how it doesn't work?

It would help if you could provide a couple of sample images that show it's not working, and/or a script and data.

Thanks,

I use gsn_csm_streamline_contour_map_ce in NCL 5.1.1 for these plots. I tried to use the following settings, but it didn't work:
