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
.
