學(xué)了一段時間ComponentOne的圖表，感覺ComponenOne圖表控件還可以，圖表樣式也較豐富，不過它的幫助全是英文的，而且有些地方寫的比較粗糙，示例程序也不夠詳細(xì). 我把它總結(jié)了一下.

使用方法        

        1.安裝好ComponentOne軟件.

         2.建立一個WEB應(yīng)用程序項目，名稱為: TextChart

         3.將ComponentOne軟件自帶的控件集DLL文件(不一定全部，只把需要的一部分)拷貝到自己剛建的

            項目TextChart的Bin目錄下面 (這里要手動放的原因是ComponentOne有時會找不到Dll)  

         4.雙擊項目里任何一個*.aspx文件，打開設(shè)計界面。 打開工具欄，在工具欄空白處右擊，選“添加/刪除”

             項,打開自定義控件窗口，在.net frame 組件選項卡下選擇ComponentOne相應(yīng)的組件，如果有清楚， 就將所有的C1開頭的全部勾選，點“確定按鈕".  則ComponentOne的控件就顯示在工具箱里面了  :)

         5. 到了這一步，就可以將ComponentOne控件像一般控件一樣直接拖動使用了. 拖C1WebChart控件到

            窗體頁面上.  然后右擊控件，選 "Chart wizard..."就可以為其設(shè)置顯示的樣式(餅圖/柱狀圖/折線圖等)和

            屬性了，用法跟一般控件差不多。(如果感覺還是陌生的話，請看下面（三）,除了用設(shè)計器設(shè)置外，

           還可以代碼用代碼設(shè)置)

代碼設(shè)置

         1. 限于篇幅，只講解主要的屬性

         2.所有的圖表樣式原理差不多都一樣的，這里只講一下餅圖的實現(xiàn)方法

   using C1.Web.C1WebChart;           

//命名空間，必需加入,否則找不到里面的類和方法等
using C1.Web.C1WebChartBase;
using C1.Win.C1Chart;

           protected C1.Web.C1WebChart.C1WebChart C1WebChart1;  

// 控件聲明

         1)  <summary>主要屬性</summary>

          C1WebChart1.Header.Text="Chart 頭";               //圖表頭標(biāo)題
          C1WebChart1.Footer.Text="Chart 尾";                 //圖表尾文本
          C1WebChart1.BackColor = Color.LightSteelBlue;   //背景色
           C1WebChart1.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;

  //圖像存儲格式         

           C1WebChart1.ChartGroups.Group0.ChartType = Chart2DTypeEnum.Bar;  

//圖表

    // 類型,Chart2DTypeEnum枚舉下有所有的圖表樣式，如餅圖/柱狀圖等                                                                                                 
            C1WebChart1.Width=800;     //圖表寬度

          2) <summary>主要方法</summary>

            a .X軸標(biāo)簽(坐標(biāo))的方法，直接調(diào)用即可

               public void AddAxisX()
               {  
                       // label x axis with product names
                      Axis ax = C1WebChart1.ChartArea.AxisX;
                      ax.ValueLabels.Clear();  
                     ax.AnnoMethod = AnnotationMethodEnum.ValueLabels;
                     for(int i = 0; i < 100; i++)
                     {
                              //DataRowView drv = dv[i];
                             ax.ValueLabels.Add(i, (i+1).ToString());
                     }
                     try
                     {
                             ax.Max = 10 - .5;
                     }
                    catch {}  
                }
             a .Y軸標(biāo)簽(坐標(biāo))的方法，直接調(diào)用即可

                public void AddAxisY()
                { 
                      // label y axis with product names
                     Axis ay = C1WebChart1.ChartArea.AxisY;
                    ay.ValueLabels.Clear();  
                   ay.AnnoMethod = AnnotationMethodEnum.ValueLabels;
                    for(int i = 0; i < 10; i++)
                    {
                          //DataRowView drv = dv[i];
                         ay.ValueLabels.Add(i, (50*i).ToString());
                   }
                   try
                    {
                            ay.Max = 20 - .5;
                    }
                   catch {}  
                 }

              c.畫圖表的方法
                public void GetPieData()
                {  
                        C1WebChart1.Legend.Visible = true;  //圖表區(qū)塊注釋.
                        this.AddAxisX();   //上面方法a
                        this.AddAxisY();   //上面方法b
   
                        //生成數(shù)據(jù)
                        PointF[] data = new PointF[10];
                         for (int i = 0; i < data.Length; i++)
                         {
                                 float y = float.Parse((3*i+5).ToString());
                                 data[i] = new PointF(i, y);
                         }    
   
                        //清除現(xiàn)有的餅圖
    ChartDataSeriesCollection dscoll =

C1WebChart2.ChartGroups[0].ChartData.SeriesList;   
                         dscoll.Clear();

                       //匯圖,即將點數(shù)組交給控件，它會自己分配,并畫出圖形
  ChartDataSeries series = C1WebChart1.ChartGroups[0].ChartData.SeriesList[0];
                        series.PointData.CopyDataIn(data);// 這里的data是PointF類型  
           
                        //給區(qū)塊加標(biāo)簽
                        for(int i=0; i < data.Length; i++)
                        {
                                ChartDataSeries series = dscoll.AddNewSeries();
                                series.PointData.Length = 1;
                                series.Y[0] = data[i].Y;
                                series.Label= "我是:"+(i+1).ToString();

                               //加標(biāo)簽
                                C1.Win.C1Chart.Label lbl = C1WebChart1.ChartLabels.LabelsCollection.AddNewLabel();
   lbl.Text = string.Format( "{0} ({1:c})","第:"+i.ToString()+"扇區(qū)", data[i].Y);
                                lbl.Compass = LabelCompassEnum.Radial;
                                lbl.Offset = 20;
                                lbl.Connected = true;
                                lbl.Visible = true;
                                lbl.AttachMethod = AttachMethodEnum.DataIndex;
                                AttachMethodData am = lbl.AttachMethodData;
                               am.GroupIndex  = 0;
                              am.SeriesIndex = i;
                              am.PointIndex  = 0;
                          }
                    }
