OWC控件的使用学习札记（三）

线性图示例：

using Microsoft.Office.Interop.Owc11; private void MakeLineChart() { //Y坐标轴 string[] DataName = { "星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日" }; //第一条曲线的数据 int[] Data = { 0, 10, 20, 100, 40, 50, 60 }; //第二条曲线的数据 int[] Data1 = { 100, 50, 41, 86 }; //第三条曲线的数据 int[] Data2 = { 10, 50, 100, 30, 50, 60 }; string strValue1 = ""; string strValue = ""; string strValue2 = ""; string strCateory = ""; //循环取得数据并格式化为OWC10需要的格式,(加'\t') for (int i = 0; i < DataName.Length; i++) { strCateory += DataName[i] + '\t'; } for (int i = 0; i < Data.Length; i++) { strValue += Data[i].ToString() + '\t'; } for (int i = 0; i < Data1.Length; i++) { strValue1 += Data1[i].ToString() + '\t'; } for (int i = 0; i < Data2.Length; i++) { strValue2 += Data2[i].ToString() + '\t'; } OWC10.ChartSpaceClass mySpace = new OWC10.ChartSpaceClass();//创建ChartSpace对象来放置图表 OWC10.ChChart myChart = mySpace.Charts.Add(0);//在ChartSpace对象中添加图表,Add方法返回chart对象 myChart.Type = OWC10.ChartChartTypeEnum.chChartTypeColumnClustered;//指定图表的类型为线性图 myChart.HasLegend = true;//指定图表是否需要图例 myChart.HasTitle = true;//给定标题 myChart.Title.Caption = "交易曲线图"; //图表名称 //给定X\Y轴的图示说明 myChart.Axes[0].HasTitle = true; myChart.Axes[0].Title.Caption = "数量"; //横轴名称 myChart.Axes[1].HasTitle = true; myChart.Axes[1].Title.Caption = "日期"; //纵轴名称 //添加一个series(序列) myChart.SeriesCollection.Add(0); //给定series的名字 myChart.SeriesCollection[0].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, "购买"); //给定series的分类 myChart.SeriesCollection[0].SetData(OWC10.ChartDimensionsEnum.chDimCategories, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strCateory); //给定具体值 myChart.SeriesCollection[0].SetData(OWC10.ChartDimensionsEnum.chDimValues, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strValue); //添加一个series myChart.SeriesCollection.Add(1); //给定series的名字 myChart.SeriesCollection[1].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, "出售"); //给定series的分类 myChart.SeriesCollection[1].SetData(OWC10.ChartDimensionsEnum.chDimCategories, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strCateory); //给定具体值 myChart.SeriesCollection[1].SetData(OWC10.ChartDimensionsEnum.chDimValues, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strValue1); //添加一个series myChart.SeriesCollection.Add(2); //给定series的名字 myChart.SeriesCollection[2].SetData(OWC10.ChartDimensionsEnum.chDimSeriesNames, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, "总成交"); //给定series的分类 myChart.SeriesCollection[2].SetData(OWC10.ChartDimensionsEnum.chDimCategories, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strCateory); //给定具体值 myChart.SeriesCollection[2].SetData(OWC10.ChartDimensionsEnum.chDimValues, (int)OWC10.ChartSpecialDataSourcesEnum.chDataLiteral, strValue2); //输出成GIF文件 string strAbsolutePath = (Server.MapPath(".")) + @"\Images\tempChart.gif"; Response.Write(strAbsolutePath); mySpace.ExportPicture(strAbsolutePath, "GIF", 300, 300); //输出图表 //创建GIF文件的相对路径 string strRelativePath = "Images/tempChart.gif"; //把图片添加到Image Image1.ImageUrl = strRelativePath;    }  }}
