Gnuplot is a command-driven interactive function plotting program. It can be used to plot functions and data points in both two- and three- dimensional plots in many different formats, and will accommodate many of the needs of today's scientists for graphic data representation. Gnuplot is copyrighted, but freely distributable; you don't have to pay for it.Probably the best way to learn gnuplot is to start using it. It has pretty good help built in, and the only command you really need to know is "plot".
You can give gnuplot commands interactively, or load chunks of code with the load command.
set xlabel "Percent vectorization" set ylabel "Net speedup" plot [x=0:100] 1/((1-(0.01*x))+((0.01*x)/20)) notitleThis program creates an eps version of the graph called "1.1.ps":

HelpNet was created by the 1995 incoming graduate class. It is only occasionally updated.
