How can I change the tickLabel on a NumberAxis in JFreeChart?

Question

I am using JFreeChart and want to be able to change the label on the range axis from a number to something more meaningful for the domain I am in. I only see options for customizing the look of the label and no way to override the content of the label based on the position of the tick.

Does anyone know how to override the text of the tickLabel?

The JFreeChart BarChartDemo1 shows how to use the setStandardTickUnits() method. NumberAxis has several handy static factories for this. To override the defaults, you can "create your own instance of TickUnits and then pass it to the setStandardTickUnits() method."

Addendum: The defaults mentioned above simply use a subclass of java.text.Format; you can supply your own for each TickUnit you add(). If this is inadequate, you can override valueToString() in your own concrete subclass of TickUnit and use it to compose the required TickUnits.
