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";
