Aspose.Words 操作 Word 画 EChart 图( 二 ) _生活百科

【Aspose.Words 操作 Word 画 EChart 图】2、单双曲线图，饼图，柱状图
曲线图需要用到 InsertChart 方法指定图表类型 Line，这三种图区别不大方法一样，只需要指定图表类型
ChartSeriesCollection seriesCollection = chart.Series; 提供了向图表插入数据的操作，有点类似 List 如果你只有一条曲线（柱状图），写一个 Add 就行，如果是多条曲线（柱状图），则添加多个 Add 数据即可展示多条曲线（柱状图）

散点图跟其他图略有区别，散点图是 XY 的坐标点形式处理数据
