Well, a line usually doesn't do a very good job of filling an area 
(special plane-filling curves like the Hilbert and Peano fractals 
excluded).  But if you really have to, a spiral should work.  You won't 
get automatic tics, though:

	factor = 100  # adjust this
	sp_x(t) = t*cos(t/factor)
	sp_y(t) = t*sin(t/factor)
	plot 'file' u (sp_x($1)):(sp_y($1))

Only if your computer's C "double" type does.  Which almost certainly it 
won't.  So you'll have to preprocess them to fit them into a less insane
dynamic range.  Just divide them all by 1e1000 or so, or logarithmize them.
