如何使用.NET Framework 3.5的Microsoft图表控件绘制雷达图表

Question

如何使用Microsoft图表控件为.NET Framework 3.5绘制雷达图表。我可以使用MSDN中的以下代码绘制“列”图表。我找不到任何雷达图的例子。

Series ChampionshipsSeries = chtNBAChampionships2.Series["Championships"]; 
    //Add data points 
    ChampionshipsSeries.Points.AddXY("Celtics", 17); 
    ChampionshipsSeries.Points.AddXY("Lakers", 15); 
    ChampionshipsSeries.Points.AddXY("Bulls", 6); 
    ChampionshipsSeries.Points.AddXY("Spurs", 4); 
    ChampionshipsSeries.Points.AddXY("76ers", 3); 
    ChampionshipsSeries.Points.AddXY("Pistons", 3); 
    ChampionshipsSeries.Points.AddXY("Warriors", 3); 

寻找您的善意帮助。

最后我管理自己做从以下源的示例进行试验后，

Samples for Chart Control - .NET Framework 4

虽然例子是.NET Framework 4中，我尝试在.NET Framework 3.5的雷达图和有效。

如果你有兴趣，你可以看看这个页面，http://nazmulweb.com/site5/demo/chart/

后来，我找到了.NET 3.5 Freamework例子从http://code.msdn.microsoft.com/mschart/Release/ProjectReleases.aspx?ReleaseId=1591

作为一个现成的参考，你可以按照这个一，

 /* 
    -------------------------- 
    Criteria Volvo Toyota 
    -------- ----- ------ 
    Speed  37  23 
    Fuel  32  19 
    Comfort  38  31 
    Safety  39  33 
    -------------------------- 
    */ 

    DataTable dt = new DataTable(); 
    dt.Columns.Add("Criteria"); 
    dt.Columns.Add("Volvo"); 
    dt.Columns.Add("Toyota"); 
    DataRow dr1 = dt.NewRow(); 
    dr1.ItemArray = new object[] { "Speed", 37, 23 }; 
    dt.Rows.Add(dr1); 
    DataRow dr2 = dt.NewRow(); 
    dr2.ItemArray = new object[] { "Fuel", 32, 19 }; 
    dt.Rows.Add(dr2); 
    DataRow dr3 = dt.NewRow(); 
    dr3.ItemArray = new object[] { "Comfort", 38, 31 }; 
    dt.Rows.Add(dr3); 
    DataRow dr4 = dt.NewRow(); 
    dr4.ItemArray = new object[] { "Price", 39, 33 }; 
    dt.Rows.Add(dr4); 

    Chart aRadarChart = new Chart(); 
    aRadarChart.Width = Unit.Pixel(500); 
    aRadarChart.DataSource = dt; 
    // Add title 
    aRadarChart.Titles.Add("TOYOTA　VS　VOLVO"); 
    // Add a legend 
    Legend lgnd = new Legend(); 
    lgnd.Enabled = true; 
    aRadarChart.Legends.Add(lgnd); 

    //Important: add ChartArea, otherwise no graph will be shown 
    ChartArea ca = new ChartArea("myChartArea"); 
    aRadarChart.ChartAreas.Add(ca); 

    string car = String.Empty; 
    for (int i = 1; i < dt.Columns.Count; i++) 
    { 
     car = dt.Columns[i].ColumnName; 

     aRadarChart.Series.Add(car);//Name of the series :Volvo and Toyota 
     aRadarChart.Series[car].YValueMembers = car;//Either Volvo or Toyota 
     aRadarChart.Series[car].XValueMember = dt.Columns[0].ColumnName;//Criteria 
     //Define here: what kind of Chart you want 
     aRadarChart.Series[car].ChartType = SeriesChartType.Radar; 
    } 

    //binding data 
    aRadarChart.DataBind(); 
    //Add Chart to a PlaceHolder Control 
plhForChart.Controls.Add(aRadarChart); 
    //Page.Controls.Add(aRadarChart); 

    //for saving image 
    aRadarChart.SaveImage(Server.MapPath("App_Data/Sample.jpg"));
