java在使用APACHE POI的PowerPoint中创建图表

我们如何使用apache poi在java中的ppt中创建图表。我们使用哪种POI API。下面是代码我用来创建一个文本框java在使用APACHE POI的PowerPoint中创建图表

XSLFSlide slide = pptx.createSlide(); 
XSLFTextShape textShape = slide.createTextBox(); 
textShape.setText(data);

的幻灯片对象犯规包含任何API来创建一个图表。

对此的任何解决方案？

在此先感谢

有没有像在apache poi PowerPoint幻灯片中可使用的XSLFChartShape直到现在。

当然但是，如果一个人知道所述*.pptxZIP归档文件的内部结构和在其中XML，则有可能使用来自org.openxmlformats.schemas.drawingml.x2006.*org.openxmlformats.schemas.presentationml.x2006.*和所述apache poiOPCPackage类和低电平CT*类创建此从头。

以下代码正在执行此操作并创建一个包含饼图和条形图的幻灯片。

这是一个草案只是为了显示方法。其产生相同的，但具有XSSFWorkbook S作为数据表

谢谢你!!这确实有用，并允许您从头开始创建图表。没有论坛有这样的工作代码。你也可以让我知道它是否可能在幻灯片中嵌入pdf。你有相同的参考吗？ Thankyou再次还有帮助我们了解pptx的低级结构的任何文档？ – user3247376

对于生成图表的上述代码，我无法在双击它时链接/编辑excel。 @Axel Richter关于如何将excel附加到图表数据的任何指针 – user3247376

@ user3247376：代码仅为图表提供了缓存值。但是如果单击“编辑数据”，“PowerPoint 2016”以及“Libreoffice Impress”能够创建数据表。但是当然'PowerPoint 2007'不会这样做。但是提供嵌入式'XSSFWorkbook'作为数据表也是可能的。看我的补充。 –
