[ncl-talk] bar chart

[Mary Haley]

There are several examples on that page of how to add a legend using
labelbars.  See:

http://www.ncl.ucar.edu/Applications/bar.shtml#ex11
http://www.ncl.ucar.edu/Applications/bar.shtml#ex22

If you don't want a labelbar, then you can use markers, text, and/or lines
to add your own legend, using calls to gsn_text_ndc, gsn_polyline_ndc,
gsn_polymarker_ndc, and gsn_polygon_nc.

The primitives page has many examples. See:
