3D plot style with zerrorfill. See zerrorfill (p. ), fenceplots (p. ) and
http://gnuplot.info/demo_5.2/zerror.htmlzerror demo.
Beeswarm plots. See set jitter (p. ), beeswarm (p. ) and

The symbol used for individual points in a plot can be controlled by data values
(see pointtype variable (p. ))
Extra lines to customize the key can be added by substituting keyentry in
place of a filename or function in plot and splot commands.
This produces a line in the key without generating a corresponding plot.
See keyentry (p. ).
