JavaFX-NumberAxis上的刻度线标签 [英] JavaFX - tick mark label on NumberAxis

问题描述

如何获取NumberAxis刻度线标签的字符串表示形式(与图形输出一样)?我可以使用哪种方法来回读NumberAxis上显示的内容. 例如，x轴正在显示(1、2、3，...，10).当我使用刻度标记标签的tickMark.getLabel()时，我得到(1.0，2.0，3.0，...，10.0).它正在返回一个双. JavaFX是否使用默认的LabelFormatter方法在将双精度字符显示在屏幕上之前将其转换为整数?

How do I get the string representation (as what is output on the graph) of the tick mark label on the NumberAxis? Which method can I use to read back what is being displayed on the NumberAxis. For example, the x-Axis is displaying (1, 2, 3, ..., 10). When I use the tickMark.getLabel() of the tick mark label, I get (1.0, 2.0, 3.0, ..., 10.0). It is returning a double. Does JavaFX use a default LabelFormatter method that converts the double to an integer before it displays on the screen?

推荐答案

NumberAxis具有一个格式化程序字段(从VaueAxis继承)，用于将值转换为字符串.请参见 http://docs.oracle.com/javase/8/javafx/api/javafx/scene/chart/ValueAxis.html#setTickLabelFormatter-javafx.util.StringConverter-

NumberAxis has a formatter field (inherited from VaueAxis) that converts the values to strings. See http://docs.oracle.com/javase/8/javafx/api/javafx/scene/chart/ValueAxis.html#setTickLabelFormatter-javafx.util.StringConverter-

如果它没有给您想要的值，您可以覆盖它.

You can overwrite it if it's not giving you the values you want.
