Java 使用org.openxmlformats.schemas.drawingml.x2006.chart绘制线图
我想用ApachePOI和excel中的OpenXmlFormats在图形中绘制三行，但是我可以绘制两行，但无法绘制第三行，我不知道为什么。所以请帮我在一张图上画三条线。 我正在共享绘制双线的代码。。 [2] 我已经添加了一个图片，我想在结果。 [3] 如何在单个excel文件中绘制多个图表Java 使用org.openxmlformats.schemas.drawingml.x2006.chart绘制线图,java,apache-poi,Java,Apache Poi,我想用ApachePOI和excel中的OpenXmlFormats在图形中绘制三行，但是我可以绘制两行，但无法绘制第三行，我不知道为什么。所以请帮我在一张图上画三条线。 我正在共享绘制双线的代码。。 [2] 我已经添加了一个图片，我想在结果。 [3] 如何在单个excel文件中绘制多个图表 public class LineChart { public static void main(String[] args) throws Exception { String
