直方图和功能图与java swing(histograms and function graphs with java swing)

Java Swing中是否有预定义的组件允许绘制直方图或函数图 ？

如果没有。 有没有人知道一个非GPL2.0 / 3.0许可证的开源库？ （我需要MIT / Apache / Eclipse / LGpl许可证下的任何产品）。

提前致谢

Is there any predefined component in Java Swing that allow to draw histograms or functions graphs?

If there is not. Does anyone know a good open-source library with a license that is not GPL2.0/3.0 ? ( I need any product licensed under MIT/Apache/Eclipse/LGpl licenses).

thanks in advance

JFreeChart是一个流行的Java库，您可以使用它来制作各种图表，包括直方图和函数图。 它获得LGPL许可证。

我觉得JFreeChart有点令人讨厌的是，您必须为开发者指南付费，并且您必须单独为该指南的每位用户付费（即一名开发人员不能合法地将其副本借给其他开发人员，除非您购买更昂贵的网站许可证）。 尽管API文档是免费的。

JFreeChart is a popular Java library with which you can make all kinds of charts, including histograms and function graphs. It's licensed with the LGPL license.

Something that I find a little annoying with JFreeChart is that you have to pay for their Developer Guide, and that you have to pay for each user of that guide separately (i.e. one developer can't legally lend his copy to another developer, unless you buy a more expensive site license). API documentation is available for free though.
