本文整理了Java中org.jfree.chart.plot.Plot类的一些代码示例，展示了Plot类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Plot类的具体详情如下：
包路径：org.jfree.chart.plot.Plot
类名称：Plot

Plot介绍

[英]The base class for all plots in JFreeChart. The JFreeChart class delegates the drawing of axes and data to the plot. This base class provides facilities common to most plot types.
[中]JFreeChart中所有绘图的基类。JFreeChart类将轴和数据的图形委托给绘图。该基类提供了大多数绘图类型通用的工具。
