Graphing Compound Interest in Java

[The Former DMiller]

I'm a bit rusty using Java...rusty meaning I remember almost nothing about programming in it. It's been over 4 years since I did anything other than short little Javascripts, but they aren't the same as full-fledged Java. What I need to do is write a program that will ask the user for four inputs: the principle, the interest, the unit of time, and the amount of time. It will then compute the compound interest and create a graph based on the data obtained. Any hints as to what I will need to do would be greatly appreciated. I don't think I've ever created graphs in Java so I'll have to be trying that out cold.
