サンプルコード

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Windows.Forms.DataVisualization.Charting;

namespace WindowsFormsApplication1
{
	public partial class Form1 : Form {
		public Form1() {
			var chart1 = new Chart {
				Dock = DockStyle.Fill,
			};
			this.Controls.Add(chart1);
			Series mySeries = new Series("series");
			double[] data = new double[] { 65.62, 75.54, 60.45, 55.73, 70.42 };
			string[] country = new string[] { "France", "Canada", "UK", "USA", "Italy" };
			mySeries.Points.DataBindXY(country, data);
			mySeries.ChartType = SeriesChartType.Pie;
			mySeries["PieLabelStyle"] = "Inside";
			mySeries["PieDrawingStyle"] = "Default";
			ChartArea myArea = new ChartArea("area");
			chart1.ChartAreas.Add("area");
			chart1.Series.Add(mySeries);
			mySeries.ChartArea = "area";
			chart1.Legends.Add(new Legend("Default"));
			LegendCellColumn firstColumn = new LegendCellColumn();
			firstColumn.ColumnType = LegendCellColumnType.SeriesSymbol;
			firstColumn.HeaderText = "";
			chart1.Legends["Default"].CellColumns.Add(firstColumn);
			LegendCellColumn percentColumn = new LegendCellColumn();
			percentColumn.Text = "#PERCENT";
			percentColumn.HeaderText = "Percentage";
			percentColumn.Name = "nameColumn";
			chart1.Legends["Default"].CellColumns.Add(percentColumn);
			chart1.Legends["Default"].LegendStyle = LegendStyle.Table;
			chart1.Legends["Default"].TableStyle = LegendTableStyle.Tall;
			chart1.Legends["Default"].DockedToChartArea = "area";
			chart1.Legends["Default"].IsDockedInsideChartArea = false;
			chart1.Legends["Default"].Docking = Docking.Bottom;
		}
		[STAThread]
		static void Main() {
			Application.Run(new Form1());
		}
	}
}

以上。
