I'd like to reiterate my opinion that it'd be nice to have a plot be
an object.  This allows us to move up a notch (out of spaghetti-like
code) and do cool things like modify existing plots:

	plot1.xlims(10,20)
	plot1.update()

to change the x-axis limits, or for example

	gwin.stackplots(2,2,plot1,plot2,plot3,plot4)

to arrange four plots in a 2x2 matrix on the graphics window 'gwin'.

Have you looked at DISLIN?  It's available in C, and looks pretty
nice.  The Linux and DOS versions are free, but unfortunately you have
to pay for the versions for other operating systems.  That's the
biggest disadvantage.  Possibly you might cut a deal with them as part
of making it a package.
