I am looking for a program that produces plots.  The features that I
am interested in are:
	- output is PostScript
	- data in from a file
	- automatically picks {x,y}axis sizes
	- {x,y}axis sizes user specifiable
	- title & axis labels user defineble
	- data points draw with either
	   - lines connecting them
	   - a marker marking point (i.e. '*' for curve 1, a '+'
	     for curve 2, a 'o' for curve 3)
	   - both
	   - dashes, dots, dot-dashes, etc
	   - greyscale/color
	- a Legend produced describing what each curve is (i.e.
	  using the file name would be good).
	- plus any others that might be good

Thanks in advance.  I will post a summary of replies, if any, that
mentions anything that satisfies the above.
