ASP.NET数据控件之Chart的用法

多加一嘴：
如若想使得网站后退按钮，可以考虑使用HiddenField存放Uri，可以加密，也可以通过this.Request.UrlReferrer获取得到URL 注意获取this.Request.UrlReferrer返回值为URI类型

直接上代码：
前台页面写法
1 <asp:Chart ID="ChartPie" runat="server" Width="950px" BackColor="#FFFFCC" Palette="BrightPastel"
2                 BorderWidth="0" BorderColor="#cc9900">
3                 <Annotations></Annotations>
4                 <Legends>
5                     <asp:Legend IsTextAutoFit="False" Name="Default" BackColor="Transparent" Font="Trebuchet MS, 8.25pt, style=Bold">
6                     </asp:Legend>
7                 </Legends>
8                 <ChartAreas>
9                     <asp:ChartArea Name="ChartArea1">
10                     </asp:ChartArea>
11                 </ChartAreas>
12 </asp:Chart>

后台：表结构如下s
后台需要的表结构
1 table = new DataTable();
2             table.Columns.AddRange(new DataColumn[]{
3                     new DataColumn("url",typeof(String)),
4                     new DataColumn("liulan",typeof(Int32)),
5                     new DataColumn("易做图",typeof(Int32)),
6                     new DataColumn("dacpno",typeof(Int32))
7                 });

Bind方式如下：
后台邦定
1 Series seriesPies = new Series("受访域名统计");
2             this.ChartPie.Series.Add(seriesPies);
3             this.ChartPie.ChartAreas[0].Area3DStyle.Enable3D = true;
4             seriesPies.ChartType = SeriesChartType.Pie;
5             seriesPies.BorderWidth = 3;
6             seriesPies.ShadowOffset = 2;
7             Title tPie = new Title("受访域名统计饼状图", Docking.Top, new Font(FontFamily.GenericSerif, 16, FontStyle.Bold), Color.Brown);
8             tPie.ShadowColor = Color.Gray;
9             tPie.ShadowOffset = 2;
10             this.ChartPie.Titles.Add(tPie);
11
12             for (int i = 0; i < this.table.Rows.Count; i++)
13             {
14                 object count = this.table.Rows[i]["liulan"];
15                 seriesPies.CustomProperties = "PieLabelStyle=Outside";//让饼状图的图示区域和图示文本用线连接
16                 seriesPies.Points.AddXY(string.Concat(this.table.Rows[i]["url"], "(", count, ")"), count);
