6. MeterPlot - Color

Instead of three fixed ranges, the MeterPlot now allows you to add an arbitrary number of "intervals" - see the addInterval() method.

Hi Jason, you set these and other attributes in the renderer. You assign a renderer to an XYPlot (or more precisely to a dataset of a plot) in the method XYPlot.setRenderer.
