Scientific plotting software?

[Kevin Dooley]

Can anybody help me with a software question?
I am working on a 386 with a mono graphics card running SCO XENIX.
I need a good scientific plotting package which can support
postscript and/or laserjet output.  By `good', I mean
	* multiple plots on a single set of axes
	* titles and legends with mixed greek and latin characters
	* log or linear x and y axes
	* distinct point markers for each curve
	* distinct line types for each curve
	* error bars (this is a biggy!)
	* multiple graphs on a single page
	* and if at all possible, 3-D
I would be happy with either PD or commercial as long as they fill
these requirements.  
	
Please respond by email as I don't read this group very often.
