5	#
6	# This widget is an X/Y plot, meant to points produced as <number>
7	# or <integer> outputs from the run of a Rappture tool. Use the
8	# "add" and "delete" methods to control the points showing on the
9	# plot. One interesting thing that this result does is configure
10	# the x-axis according to the current result control (simulation
11	# number or other active parameter).
