dotnetcharting 產生柱狀圖，餅圖等統計圖

標籤：

DotNetCharting是一個非常棒的.NET圖表控制項，對中文支援非常好，而且操作方便，開發快速，既有for webform 也有for winform的，而且.net1.1和2.0都有支援。官方地址是http://www.dotnetcharting.com/

簡單使用方法：

1.首先要搞定協助文檔：從官方網站下載解壓後把dotnetcharting4.2for1.x目錄設定成虛擬目錄，.net1.1的環境，然後就可以看協助樣本了。
2.把\bin\dotnetCHARTING.dll添加到工具箱，並且添加引用
3.把控制項拖到你的網頁上，然後添加引用using dotnetCHARTING;就可以用了
4.說下簡單的柱狀圖的用法（動態擷取資料）：它有個type屬性決定是柱狀圖還是餅圖或是其他，設定成Combo就是柱狀圖；

 private void Drawing(Arraylist list)        {                      Charting show = new Charting();            show.Title =  "MyChart";            show.YTitle = "Y Axis Label";            show.XTitle = "X Axis Label";            show.PicHight = 400;            show.PicWidth = 400;            show.SeriesName = "具體詳情";            show.PhaysicalImagePath = @"~/pictrue";  //此為圖片儲存的路徑，不存在則會無法顯示（下同）            show.FileName = "Combo.png";            show.Type = ChartType.Combo;//combo為柱狀圖，pie為餅圖            show.Use3D = false;                       show.DataSource = GetDataSource();            show.CreateStatisticPic(this.Chart1);    }  private SeriesCollection GetDataSource()        {             SeriesCollection SC = new SeriesCollection();             Random myR = new Random();             for(int a = 0; a < 4; a++)             {                  Series s = new Series();                  s.Name = "Series " + a;                  for(int b = 0; b < 5; b++)                  {                       Element e = new Element();                       e.Name = "E " + b;                       e.YValue = myR.Next(50);                       s.Elements.Add(e);                  }                  SC.Add(s);               }                    }
