[ncl-talk] legend

[Mary Haley]

Sandro,

On the same legend page that Rick pointed you to, you could also check out
the "simple_legend" function that Adam Phillips created. Examples 16, 17,
and 19 show how to use this function.

If you need to draw the legend outside the plot, then simple_legend_ndc can
be used. This function has not yet been released, so I've attached it here.
You would need to load it with:

load "./simple_legend_ndc.ncl"

Examples 20 and 21 show how to use that function.

--Mary
