You can probably find a chart drawing library out on the 'net if you search around for it. I played with something called JFreeChart once, but I don't recall the specifics of their licensing. Otherwise, you can always create a custom Swing component (sub-class a plain JPanel, for example) and override the paintComponent method to directly draw your own axes, tick marks, and plotting lines.
