ZedGraph 在项目中的简单应用

 Step1 :   下载 ZedGraph 4.6 (.net 1.1)
 Step2 :   在vs2003.net 中项目中添加引用   ZedGraph.dll  和  ZedGraph.Web.dll
 Step3 :   在工具箱中添加   ZedGraph.Web.dll 
 Step4 :   拖拽刚添加的可视化组件 
 Step5 :   aspx页面生成代码   

<%@ Register TagPrefix="cc1" Namespace="ZedGraph.Web" Assembly="ZedGraph.Web" %>
<%@ Page language="c#" Codebehind="netpictest.aspx.cs" AutoEventWireup="false" Inherits="WS.Webs.netpictest" %>

 </body>
</HTML>

   this.Load += new System.EventHandler(this.Page_Load);
   this.ZedGraphWeb1.RenderGraph +=new ZedGraphWebControlEventHandler(this.OnRenderGraph);


  }
  #endregion


  private void OnRenderGraph(ZedGraphWeb zgw, Graphics g, MasterPane masterPane)
  {
   // Get the GraphPane so we can work with it
   GraphPane myPane = masterPane[0];

   myPane.Title.Text = "销售统计";
   myPane.XAxis.Title.Text = "区域";
   myPane.YAxis.Title.Text = "销售总额: 元";
 
   PointPairList list = new PointPairList();
   PointPairList list2 = new PointPairList();
   PointPairList list3 = new PointPairList();
   Random rand = new Random();

   for (double x = 0; x < 5; x += 1.0)
   {
    double y = rand.NextDouble() * 100;
    double y2 = rand.NextDouble() * 100;
    double y3 = rand.NextDouble() * 100;
    list.Add(x, y);
    list2.Add(x, y2);
    list3.Add(x, y3);
   }
 
   BarItem myCurve = myPane.AddBar("购买", list, Color.Blue);
   myCurve.Bar.Fill = new Fill(Color.Blue, Color.White, Color.Blue);
   BarItem myCurve2 = myPane.AddBar("续费", list2, Color.Red);
   myCurve2.Bar.Fill = new Fill(Color.Red, Color.White, Color.Red);
   BarItem myCurve3 = myPane.AddBar("升级", list3, Color.Green);
   myCurve3.Bar.Fill = new Fill(Color.Green, Color.White, Color.Green);
 
   myPane.XAxis.MajorTic.IsBetweenLabels = true;
   string[] labels = { "域名", "主机", "数据库", "邮局", "套餐" };
   myPane.XAxis.Scale.TextLabels = labels;
   myPane.XAxis.Type = AxisType.Text;
   myPane.Fill = new Fill(Color.White, Color.FromArgb(200, 200, 255), 45.0f);
   myPane.Chart.Fill = new Fill(Color.White, Color.LightGoldenrodYellow, 45.0f);

   masterPane.AxisChange(g);
  }

 }
}

Step7 : 在项目中创建默认的图片保存路径文件夹  ZedGraphImages

最后效果如下:
