Aspose.Words 操作 Word 画 EChart 图

　　使用 Aspose.Words 插件在 Word 画 EChart 图

　　使用此插件可以画出丰富的 EChart 图，API 参考 https://reference.aspose.com/words/net/aspose.words.drawing.charts/charttype/

　　首先需要在 vs 中引入插件

　　

　　代码中添加引用

using Aspose.Words;
using Aspose.Words.Drawing.Charts;
using Aspose.Words.Tables;

　　1、插入文字内容和表格

　　　　我们只需要获取模板，并且创建一个文档对象，将内容写入进去即可

　　　　创建表格时，需要创建头，规定每个单元格长度，宽度，将对应的数据库字段对应上

 1 DataTable dt = new DataTable();
 2
 3             //读取 Word 模板
 4             Document doc = new Document("C:\\TestProject\\WebApplication1\\WebApplication1\\Word\\AsposeWord.doc");
 5
 6             //创建文档对象
 7             DocumentBuilder builder = new DocumentBuilder(doc);
 8
 9             #region 插入文字信息
10             //Word 中对应书签的名称
11             builder.MoveToBookmark("文章标题");
12
13             //写入内容
14             builder.Write("学会使用AsposeWord画EChart图");
15             #endregion
16
17             #region 列表
18             builder.MoveToBookmark("学生信息列表");
19
20             Aspose.Words.Tables.Table table3 = builder.StartTable();//开始画Table
21             string[] columnheadersWD = { "序号", "姓名", "学科", "分数", "性别", "年龄" };
22             string[] columnnamesWD = { "ID", "TNAME", "DNAME", "SAL", "TSEX", "AGE" };
23             double[] colwidthsWD = { 50, 100, 100, 50, 50, 50 };
24
25             dt = DBHelper.ExecuteDataTable("SELECT top 5 * FROM [testdb].[dbo].[TEACHER]");
26
27             InsertTable(builder, table3, columnheadersWD, columnnamesWD, colwidthsWD, dt);
28
29             //第三列的 第三行，第四行 合并
30             MergeCells(table3.Rows[3].Cells[2], table3.Rows[4].Cells[2]);
31             #endregion

　　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）
