如何在JFreeChart中更改NumberAxis上的tickLabel? [英] How can I change the tickLabel on a NumberAxis in JFreeChart?
问题描述
我正在使用JFreeChart,并希望能够将范围轴上的标签从数字更改为对我所在域更有意义的内容。我只看到用于自定义标签外观的选项,无法覆盖基于刻度线位置的标签内容。
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.
有谁知道如何覆盖tickLabel的文本?
Does anyone know how to override the text of the tickLabel?
推荐答案
JFreeChart BarChartDemo1
显示如何使用 setStandardTickUnits()
方法。 NumberAxis
有几个方便的静态工厂。要覆盖默认值,您可以创建自己的 TickUnits
然后将其传递给 setStandardTickUnits()
方法。
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."
附录:上面提到的默认值只使用 java.text.Format
的子类;你可以为每个 TickUnit
提供你自己的 add()
。如果这不合适,你可以覆盖 TickUnit
并用它来组成所需的 TickUnits
一>。
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
.
