dotnetcharting 生成柱状图，饼图等统计图

DotNetCharting是一个非常棒的.NET图表控件，对中文支持非常好，而且操作方便，开发快速，既有for webform 也有for winform的，而且.net1.1和2.0都有支持。官方地址是http://www.dotnetcharting.com/

简单使用方法：

1.首先要搞定帮助文档：从官方网站下载解压后把dotnetcharting4.2for1.x目录设置成虚拟目录，.net1.1的环境，然后就可以看帮助示例了。
2.把\bin\dotnetCHARTING.dll添加到工具箱，并且添加引用
3.把控件拖到你的网页上，然后添加引用using dotnetCHARTING;就可以用了
4.说下简单的柱状图的用法（动态获取数据）：它有个type属性决定是柱状图还是饼图或是其他，设置成Combo就是柱状图；

 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 = "具体详情";
            show.PhaysicalImagePath = @"~/pictrue";  //此为图片保存的路径，不存在则会无法显示（下同）
            show.FileName = "Combo.png";
            show.Type = ChartType.Combo;//combo为柱状图，pie为饼图
            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);
               }
         }
