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
这里我们将画表格的方法和合并单元格的方法封装好了
1 ///2 /// 列表表格 3 /// 4 /// 5 /// 6 /// 7 /// 8 /// 9 /// 10 public static void InsertTable(DocumentBuilder builder, Aspose.Words.Tables.Table table, string[] columnheaders, string[] columnnames, double[] colwidths, DataTable statisTable) 11 { 12 var str = ""; 13 14 #region 画表头 15 for (int i = 0; i < columnheaders.Length; i++) 16 { 17 str = columnheaders[i]; 18 builder.InsertCell(); 19 //Table单元格边框线样式 20 builder.CellFormat.Borders.LineStyle = LineStyle.Single; 21 //Table此单元格宽度 22 builder.RowFormat.Height = 30; 23 builder.CellFormat.Width = colwidths[i]; 24 //此单元格中内容垂直对齐方式 25 builder.CellFormat.VerticalAlignment = Aspose.Words.Tables.CellVerticalAlignment.Center; 26 builder.CellFormat.HorizontalMerge = Aspose.Words.Tables.CellMerge.None; 27 builder.CellFormat.VerticalMerge = Aspose.Words.Tables.CellMerge.None; 28 //字体大小 29 builder.Font.Size = 10; 30 //是否加粗 31 builder.Bold = false; 32 //向此单元格中添加内容 33 builder.Write(str); 34 } 35 builder.EndRow(); 36 #endregion 37 38 #region 画数据 39 for (int j = 0; j < statisTable.Rows.Count; j++) 40 { 41 for (int i = 0; i < columnheaders.Length; i++) 42 { 43 try 44 { 45 str = statisTable.Rows[j][columnnames[i]].ToString(); 46 } 47 catch (Exception e) { str = ""; } 48 builder.InsertCell(); 49 //Table单元格边框线样式 50 builder.CellFormat.Borders.LineStyle = LineStyle.Single; 51 //Table此单元格宽度 52 builder.RowFormat.Height = 30; 53 builder.CellFormat.Width = colwidths[i]; 54 55 //builder.CellFormat.Shading.ForegroundPatternColor = Color.Red;//设置单元格颜色 56 57 //此单元格中内容垂直对齐方式 58 builder.CellFormat.VerticalAlignment = Aspose.Words.Tables.CellVerticalAlignment.Center; 59 builder.CellFormat.HorizontalMerge = Aspose.Words.Tables.CellMerge.None; 60 builder.CellFormat.VerticalMerge = Aspose.Words.Tables.CellMerge.None; 61 //字体大小 62 builder.Font.Size = 10; 63 //是否加粗 64 builder.Bold = false; 65 //向此单元格中添加内容 66 builder.Write(str); 67 } 68 builder.EndRow(); 69 } 70 #endregion 71 72 //Table行结束 73 builder.EndTable(); 74 table.AutoFit(Aspose.Words.Tables.AutoFitBehavior.FixedColumnWidths); 75 table.Alignment = Aspose.Words.Tables.TableAlignment.Center; 76 } 77 78 /// 79 /// 合并单元格 80 /// 81 /// 82 /// 83 public static void MergeCells(Cell startCell, Cell endCell) 84 { 85 Aspose.Words.Tables.Table parentTable = startCell.ParentRow.ParentTable; 86 87 // Find the row and cell indices for the start and end cell. 88 Point startCellPos = new Point(startCell.ParentRow.IndexOf(startCell), parentTable.IndexOf(startCell.ParentRow)); 89 Point endCellPos = new Point(endCell.ParentRow.IndexOf(endCell), parentTable.IndexOf(endCell.ParentRow)); 90 // Create the range of cells to be merged based off these indices. Inverse each index if the end cell if before the start cell. 91 Rectangle mergeRange = new Rectangle(Math.Min(startCellPos.X, endCellPos.X), Math.Min(startCellPos.Y, endCellPos.Y), Math.Abs(endCellPos.X - startCellPos.X) + 1, 92 Math.Abs(endCellPos.Y - startCellPos.Y) + 1); 93 94 foreach (Row row in parentTable.Rows) 95 { 96 foreach (Cell cell in row.Cells) 97 { 98 Point currentPos = new Point(row.IndexOf(cell), parentTable.IndexOf(row)); 99 100 // Check if the current cell is inside our merge range then merge it. 101 if (mergeRange.Contains(currentPos)) 102 { 103 if (currentPos.X == mergeRange.X) 104 cell.CellFormat.HorizontalMerge = CellMerge.First; 105 else 106 cell.CellFormat.HorizontalMerge = (CellMerge.Previous); 107 108 if (currentPos.Y == mergeRange.Y) 109 cell.CellFormat.VerticalMerge = (CellMerge.First); 110 else 111 cell.CellFormat.VerticalMerge = (CellMerge.Previous); 112 } 113 } 114 } 115 }
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）
1 #region 曲线 2 builder.MoveToBookmark("双曲线"); 3 var shape = builder.InsertChart(ChartType.Line, 430, 210);//插入线形图 4 Chart chart = shape.Chart; 5 ChartSeriesCollection seriesCollection = chart.Series; 6 seriesCollection.Clear();//清除默认 7 chart.Title.Text = "双曲线"; 8 chart.AxisX.TickLabelPosition = AxisTickLabelPosition.Low; 9 10 dt = DBHelper.ExecuteDataTable("select top 5 TNAME,sal,sal+100 as SAL1 from TEACHER"); 11 12 var categories = new string[dt.Rows.Count]; 13 var values = new double[dt.Rows.Count]; 14 var values1 = new double[dt.Rows.Count]; 15 16 for (int rowIndex = 0; rowIndex < dt.Rows.Count; rowIndex++) 17 { 18 categories[rowIndex] = dt.Rows[rowIndex][0].ToString(); 19 values[rowIndex] = Convert.ToDouble(dt.Rows[rowIndex][1]); 20 values1[rowIndex] = Convert.ToDouble(dt.Rows[rowIndex][2]); 21 } 22 23 chart.Legend.Position = LegendPosition.Top; 24 25 seriesCollection.Add("线条一", categories, values);//添加数据 26 seriesCollection.Add("线条二", categories, values1);//添加数据 27 #endregion 28 29 #region 饼状图 30 dt = DBHelper.ExecuteDataTable("select top 1 sal,sal+100 as SAL1,sal+200 as SAL2 from TEACHER"); 31 32 Listlist1 = new List (); 33 for (int i = 0; i < dt.Rows.Count; i++) 34 { 35 list1.Add(new CountModel { mark = "一", num = Convert.ToDouble(dt.Rows[i][0]) }); 36 list1.Add(new CountModel { mark = "二", num = Convert.ToDouble(dt.Rows[i][1]) }); 37 list1.Add(new CountModel { mark = "三", num = Convert.ToDouble(dt.Rows[i][2]) }); 38 } 39 40 builder.MoveToBookmark("饼状图"); 41 var shape1 = builder.InsertChart(ChartType.Pie, 430, 210);//插入线形图 42 Chart chart1 = shape1.Chart; 43 ChartSeriesCollection seriesCollection1 = chart1.Series; 44 seriesCollection1.Clear();//清除默认 45 chart1.Title.Text = "饼状图"; 46 47 var categories2 = new string[list1.Count]; 48 var values2 = new double[list1.Count]; 49 50 for (int rowIndex = 0; rowIndex < list1.Count; rowIndex++) 51 { 52 categories2[rowIndex] = list1[rowIndex].mark.ToString(); 53 values2[rowIndex] = Convert.ToDouble(list1[rowIndex].num); 54 } 55 56 chart1.Legend.Position = LegendPosition.Top; 57 58 seriesCollection1.Add("饼状图", categories2, values2);//添加数据 59 #endregion 60 61 #region 柱状图 62 dt = DBHelper.ExecuteDataTable("select top 5 tname,sal,sal+100 as SAL1,sal+200 as SAL2 from TEACHER"); 63 64 builder.MoveToBookmark("柱状图"); 65 var shape2 = builder.InsertChart(ChartType.Column, 430, 210);//插入线形图 66 Chart chart2 = shape2.Chart; 67 ChartSeriesCollection seriesCollection3 = chart2.Series; 68 seriesCollection3.Clear();//清除默认 69 chart2.Title.Text = "柱状图"; 70 chart2.AxisX.TickLabelPosition = AxisTickLabelPosition.Low; 71 72 var categories3 = new string[dt.Rows.Count]; 73 var values11 = new double[dt.Rows.Count]; 74 var values22 = new double[dt.Rows.Count]; 75 var values3 = new double[dt.Rows.Count]; 76 77 for (int rowIndex = 0; rowIndex < dt.Rows.Count; rowIndex++) 78 { 79 categories3[rowIndex] = dt.Rows[rowIndex][0].ToString(); 80 values11[rowIndex] = Convert.ToDouble(dt.Rows[rowIndex][1]); 81 values22[rowIndex] = Convert.ToDouble(dt.Rows[rowIndex][2]); 82 values3[rowIndex] = Convert.ToDouble(dt.Rows[rowIndex][3]); 83 } 84 85 chart2.Legend.Position = LegendPosition.Top; 86 87 seriesCollection3.Add("一", categories3, values11);//添加数据 88 seriesCollection3.Add("二", categories3, values22);//添加数据 89 seriesCollection3.Add("三", categories3, values3);//添加数据 90 #endregion
3、散点图
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
1 #region 散点图 2 var result = new List(); 3 result.Add(new SD() { wd = 15, wy = 16 }); 4 result.Add(new SD() { wd = 14, wy = 23 }); 5 result.Add(new SD() { wd = 34, wy = 23 }); 6 result.Add(new SD() { wd = 12, wy = 23 }); 7 result.Add(new SD() { wd = 34, wy = 45 }); 8 result.Add(new SD() { wd = 32, wy = 23 }); 9 result.Add(new SD() { wd = 45, wy = 56 }); 10 result.Add(new SD() { wd = 34, wy = 55 }); 11 12 builder.MoveToBookmark("散点图"); 13 var shape3 = builder.InsertChart(ChartType.Scatter, 430, 210);//插入线形图 14 Chart chart3 = shape3.Chart; 15 ChartSeriesCollection seriesCollection4 = chart3.Series; 16 seriesCollection4.Clear();//清除默认 17 chart3.Title.Text = "散点图"; 18 chart3.AxisX.TickLabelPosition = AxisTickLabelPosition.Low; 19 20 var categories4 = new double[result.Count]; 21 var values4 = new double[result.Count]; 22 23 for (int i = 0; i < result.Count; i++) 24 { 25 categories4[i] = Convert.ToDouble(result[i].wd); 26 values4[i] = Convert.ToDouble(result[i].wy); 27 } 28 29 chart3.Legend.Position = LegendPosition.Top; 30 seriesCollection4.Add("散点图", categories4, values4);//添加数据 31 #endregion
最后将内容输出到指定的新文档中
1 string cpath = "C:\\TestProject\\测试文档存放\\文档" + DateTime.Now.ToString("ddhhmmss") + ".doc"; 2 doc.Save(cpath); 3 doc.Save(cpath.Replace(".doc", ".pdf"), SaveFormat.Pdf); //同时转成 PDF 生成一份
这里只是简单的操作显示图表，如果需要具体详细的细节操作，参考官方提供的API文档。
