public class BarMeter
extends javax.swing.JPanel
```
BarMeter presents a vertical, block-style meter to present numerical information as a fraction of a number of divisions (eg, progress or resource consumption). The default number of divisions is variable, but the default is 1. The meter represents inputted values as one of either color, one "Used" and the other "Un-Used." Used are filled in to the the percentage value inputted (integer) divided by the number of divisions. The default color used is Green, and default unused is Dark Grey.
