什么开源 Java 图表库可以在类别条形图中标记域？
我正在条形图中绘制数据，并希望在特定条形之间绘制垂直线以将绘图分割为域：
我一直无法找到可以执行此操作的库。 jfreechart 有所谓的域标记，但通过条形图的中间绘制它们，因此您实际上是在标记单个条形图而不是域：
有谁知道一个可以实现我想要的功能的库吗？
I'm plotting my data in a bar chart and would like to draw vertical lines between particular bars to segment the plot into domains:
I haven't been able to find a library that can do this. jfreechart has so called domain markers but draws them through the middle of the bars, so you're really marking individual bars instead of domains:
Does anyone know a library that can do what I want?

JFreechart包含许多Marker子类，它们是如图所示杂项 > 示例的标记部分。此外，许多绘图允许自定义网格线和/或十字线Stroke。对于任意线条和形状，请考虑org.jfree.chart.annotations，如XYLineAnnotation，演示了此处。JFreechartincludes a number ofMarkersubclasses that are pictured among theMiscellaneous > Markerssection of the samples. In addition, many plots allow customizing the gridline and/or crosshairStroke. For arbitrary lines and shapes, consider one of theorg.jfree.chart.annotations, such asXYLineAnnotation, demonstrated here.
