[Techtalk] Linux graphing program

[Kathy Gerber]

Mary and Dan,

Even if it's more than you asked for, I can't recommend R enough ( 
http://www.r-project.org/ ).  Certainly larger than gnuplot, it has 
proportionate capabilities, and even if you use it only for a super 
calculator, it's well worth the trouble.  The basic command for your 
function would be
 > curve(6*x^3 -5*x,-5,5)
where -5 to 5 is the domain of the graph.

You can customize the plot, adding colors, lables, etc.etc.

R is also an impressive number cruncher and outperforms many popular 
commercial products in this benchmark suite -

Just scratching the surface - but give it a try if you get a chance.
