1.添加引用 System.Web.DataVisualization

配置文件文件中会增加三个内容

2.前台代码

                 
                      
                       
                   
                  
       -- 背景为圆角            
      
        -- 曲线的控制                
                       
                       
                       
                   
                  
                      
                           
                            
        
          --Y轴                         
                                 
                             
                            
        
          -- X轴                         
                                 
                             
                        
                   
              
     

3.后台

　　using System.Web.UI.DataVisualization.Charting; protected void Page_Load(object sender, EventArgs e)    {        // Populate series with random data        Random random = new Random();        for (int pointIndex = 0; pointIndex < 10; pointIndex++)        {            Chart1.Series["Series1"].Points.AddY(random.Next(45, 95));            Chart1.Series["Series2"].Points.AddY(random.Next(5, 75));        }        // Set series chart type        Chart1.Series["Series1"].ChartType = SeriesChartType.Line;        Chart1.Series["Series2"].ChartType = SeriesChartType.Spline;        // Set point labels        Chart1.Series["Series1"].IsValueShownAsLabel = true;        Chart1.Series["Series2"].IsValueShownAsLabel = true;        // Enable X axis margin        Chart1.ChartAreas["ChartArea1"].AxisX.IsMarginVisible = true;        // Enable 3D, and show data point marker lines        Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;        Chart1.Series["Series1"]["ShowMarkerLines"] = "True";        Chart1.Series["Series2"]["ShowMarkerLines"] = "True";    }
