For what it's worth, I've found a tool called "grace" 
(plasma-gate.weizmann.ac.il/Grace/) to be really useful.  It seems to be 
more flexible than gnuplot, and has both a WYSIWYG graphical interface 
and a batch-driven one.  With a little ugly perl wrapped around the 
batch function, I've been able to automate the production of nice 
looking graphs for my web site.
