Java 甜甜圈图ApachePOI,java,excel,apache-poi,Java,Excel,Apache Poi,我正在尝试用ApachePOI创建甜甜圈图，但没有任何信息或示例。我尝试使用饼图的例子，但没有成功。你能帮我解决这个问题吗首先请注意，对于下面的每个解决方案，都需要完整的jar，其中包含所有模式ooxml-schemas-1.4.jar较低版本，用于较旧的版本，如中所述 apache poi中没有甜甜圈图表数据类型。因此，在大多数apache poi版本中使用的最简单方法是使用org.openxmlformats.schemas.drawingml.x2006.chart的低级类例如： im

嗨，阿克塞尔，你能提供一个4.1.2甜甜圈图表版本吗？@Doron Levi:不，我不能，因为org.apache.poi.xddf.usermodel.chart.xddf甜甜圈图表数据到目前为止是不完整和无用的。但是我的ApachePOI4.1.1示例使用我自己的XDDFDoughnutChartData，也可以使用ApachePOI4.1.2。@Doron Levi:请阅读我答案中的第一句话。您需要所有模式的完整jar ooxml-schemas-1.4.jar。
