Uh, is this a standalone application, such as a Swing app or AWT app,
an applet run in a browser, or a server side servlet or JSP?
Also, how "professional" do you want the results to be? If you want
really fancy, professional looking stuff, buy a commercial graphics
API. If you have no money, there are a couple of decent packages,
sans a few bells and whistles, at sourceforge.net. Look into JChart
and/or JFreeChart. If you want to simply plot the data yourself by
"brute force," create a java.awt.Component, override its update and
paint methods, casting the Graphics to a Graphics2D, and start doing
computations and drawing lines. Put your component into any
container, and presto --- instant graph. Well, not quite; you'll have
days of programming, in all likelihood.
