Excel 生成 [Java] - 条形图 - 启用多类别标签
Excel Generation [Java] - BarChart - Enable Multi Category Label
我有 excel 代使用 org.apache.poi 库。在这里我需要生成一个条形图，它应该如下所示：
我的 excel 看起来像：
代码：
//CellRangeAddress(int firstRow, int lastRow, int firstCol, int lastCol)
XDDFDataSource<String> department = XDDFDataSourcesFactory.fromStringCellRange(sheet,
new CellRangeAddress(7, 17, 1, 1));
如果我设置 CellRangeAddress firstCol - 0 和 lastCol - 1 它不起作用？
在 java:
中是否有任何选项可以启用此功能
使用 apache poi 的 XDDF 内容无法实现多级类别标签。 XDDF 始终使用 StrRef 作为图表数据源的参考。要创建多级类别标签，必须使用 MultiLvlStrRef。所以这个任务只能直接使用低级别 org.openxmlformats.schemas.drawingml.x2006.chart.* classes 来解决。
这就是为什么以下代码需要所有 ooxml-schemas 的完整 jar，即 class 路径中当前 apache poi 4.1.2 的 ooxml-schemas-1.4.jar。 poi-ooxml-schemas-4.1.2.jar 不包含 org.openxmlformats.schemas.drawingml.x2006.chart.CTMultiLvlStrRef.
并且由于 Microsoft 的粗略逻辑，它使用设置 NoMultiLvlLbl-true 作为类别轴的默认值，现在必须告诉类别轴它 not 没有多级标签。所以，如果轴要有多级类别标签，必须设置NoMultiLvlLblfalse。好吧，看来 Microsoft 想检查程序员是否学好他们的逻辑课程 ;-)。
