                </asp:Series>
            </series>
            <chartareas>
                <asp:ChartArea Name="ChartArea1">
                </asp:ChartArea>
            </chartareas>
        </asp:Chart>

CS代码

 protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = FillData();
            DataView dv = dt.DefaultView;
            Chart1.Series["Series1"].Points.DataBindXY(dv, "Name", dv, "Count");

            //Set the chart type  

            Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;

            // Set the bar width  
            Chart1.Series["Series1"]["PointWidth"] = "0.5";


            // Show data points labels  
            Chart1.Series["Series1"].IsValueShownAsLabel = true;

            // Set data points label style  
            Chart1.Series["Series1"]["BarLabelStyle"] = "Center";

            Chart1.Series["Series1"].Label = "#PERCENT";
            Chart1.Series["Series1"].LegendText = "#AXISLABEL";

            Chart1.Series["Series1"]["PieLabelStyle"] = "Outside";

            // Show chart as 3D  
            Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;
            Chart1.ChartAreas["ChartArea1"].Area3DStyle.WallWidth = 10;

            // Draw chart as 3D Cylinder  
            Chart1.Series["Series1"]["DrawingStyle"] = "Cylinder";

        }

        private DataTable FillData()
        {
            DataTable dt = new DataTable();
            DataColumn dc;

            dc = new DataColumn();
            dc.ColumnName = "Name";
            dt.Columns.Add(dc);
            dc = new DataColumn();
            dc.ColumnName = "Count";
            dt.Columns.Add(dc);

            DataRow dr;
            dr = dt.NewRow();
            dr["Name"] = "Fred";
            dr["Count"] = "54";
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["Name"] = "Bill";
            dr["Count"] = "66";
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["Name"] = "Rhona";
            dr["Count"] = "32";
            dt.Rows.Add(dr);

            return dt;
        }
