java使用APACHE POI在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。 下面是我用来创建文本框的代码
XSLFSlide slide = pptx.createSlide(); XSLFTextShape textShape = slide.createTextBox(); textShape.setText(data); 幻灯片对象不包含用于创建图表的任何API。
对此有何解决方案？
提前致谢
XSLFChartShape ，在apache poi的powerpoint幻灯片中没有像XSLFChartShape这样的XSLFChartShape 。
但是当然如果知道*.pptx ZIP存档的内部结构和其中的XML ，那么可以使用apache poi OPCPackage类和org.openxmlformats.schemas.drawingml.x2006.*的低级CT*类从头开始创建。 org.openxmlformats.schemas.drawingml.x2006.*和org.openxmlformats.schemas.presentationml.x2006.* 。
以下代码执行此操作并创建具有饼图和条形图的幻灯片。
这只是一个草案，以显示方法。
