[ncl-talk] Legend Line orientation

[Adam Phillips]

Hi Alex,
I believe you are running into a limitation of NCL's legend creation
capabilities. You cannot lay the legend out the way you want to with a
single gsn_create_legend call. I think the best thing to do would be to
call gsn_create_legend for every "column" that you require (=3), similar to
what was done in example #6 here:
http://www.ncl.ucar.edu/Applications/unique.shtml#ex6

This could potentially be automated either within your script or by
creating your own function.

Hope that helps!
Adam
