Re: legend and annotation

Hi Fan,

I've created an example for you. See example 11 at:

http://www.ncl.ucar.edu/Applications/legend.shtml

If you indeed want to move the legend to a second page, you can't use
the
legend that comes with the XY plot. Instead, you need to use
gsn_legend_ndc
or gsn_create_legend to create your own legend.

This example shows how to use gsn_legend_ndc.

You are also very close with your resource settings for the legend.
The example shows how to do this using resources you set for the XY
plot.
