生成图表

<p>在ASP.Net自带的Chartlet生成图表。</p>

1.添加程序集Chartlet.dll的引用（系统自带）否则找不到FanG命名空间

2.在页面上注册命名空间：<%@ Register assembly="Chartlet" namespace="FanG" tagprefix="shit" %>，也可以在配置文件里配制。

3.现在就可以写代码了<shit:Chartlet ID="Chartlet1" runat="server" Width="800px" Height="500px" />

前端Code：

 1 <%@ Register assembly="Chartlet" namespace="FanG" tagprefix="shit" %>
 2 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 3 
 4 <html xmlns="http://www.w3.org/1999/xhtml">
 5 <head runat="server">
 6     <title>JS正则验证文本框的值</title>
 7 </head>
 8 <body>
 9     <form id="form1" runat="server">
10     <div align="center">
11             <shit:Chartlet ID="Chartlet1" runat="server" Width="800px"  Height="500px" />
12     </div>
13     </form>
14 </body>
15 </html>

后台Code：

 1 if (!IsPostBack)
 2             {
 3                 string pass = "90";
 4                 string oppo = "54";
 5                 string aband = "66";
 6                 if (pass!="")
 7                 {
 8                     Chartlet1.Visible = true;
 9                     ArrayList ColorGuider = new ArrayList();
10                     List<ArrayList> DataArray = new List<ArrayList>();
11                     ArrayList XLabel = new ArrayList();
12                     ColorGuider.Add("钢欣");
13                     ColorGuider.Add("木材");
14                     ColorGuider.Add("棉花");
15                     XLabel.Add("Ariel");
16                     string[] xlable = { pass, oppo, aband };
17                     ArrayList item;
18                     for (int i = 0; i < xlable.Count(); i++)
19                     {
20                         item = new ArrayList();
21                         item.Add(xlable[i]);
22                         DataArray.Add(item);
23                     }
24                     Chartlet1.ChartTitle.Text = "按Ariel统计";
25                     Chartlet1.XLabels.UnitText = "2013年8月16日";
26                     Chartlet1.YLabels.UnitText = "日销售量（kg）";
27                     Chartlet1.InitializeData(DataArray.ToArray(), XLabel, ColorGuider);
28                 }
29                 else
30                 {
31                     
32                     Chartlet1.Visible = false;
33                 }
34             }
