我想在CombinedDomainXYPlot中显示一个标记。这是行不通的。我可以为每个子图添加标记。但我想将其添加到CombinedDomainXYPlot中。任何可以告诉我有关此问题的信息的人。我认为使用十字准线的行为是相同的。
这个工作示例创建了CombinedDomainXYPlot并尝试添加标记。标记添加在createCombinedChart()中

最佳答案
drawAnnotations是在XYPlot中实现的，不幸的是CombinedDomainXYPlot是XYPlot的子类，但是在其drawAnnotations的重写实现中没有调用draw或将注释转发到子图上。
您可以通过子类化addAnnotation来提供removeAnnotation和CombinedDomainXYPlot的隐含形式。
