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);
			string[] legends = new string[] { "グラフ１", "グラフ２" };
			string[] xValues = new string[] { "A", "B", "C", "D", "E" };
			int[,] yValues = new int[,] {{ 10, 20, 30, 40, 50 }, {20, 40, 60, 80, 100}};
			chart1.Series.Clear();
			chart1.ChartAreas.Clear();
			chart1.Titles.Clear();
			foreach (var item in legends)
			{
				chart1.Series.Add(item);
				chart1.Series[item].ChartType = SeriesChartType.StackedColumn;
				chart1.Series[item].LegendText = item;
			}
			for (int i = 0; i < xValues.Length; i++)
			{
				for (int j = 0; j < yValues.GetLength(0); j++)
				{
					DataPoint dp = new DataPoint();
					dp.SetValueXY(xValues[i], yValues[j, i]);
					dp.IsValueShownAsLabel = true;
					chart1.Series[legends[j]].Points.Add(dp);
				}
			}
			ChartArea area1 = new ChartArea();
			area1.AxisX.Title = "Title-XAxis";
			area1.AxisY.Title = "Title-YAxis";
			Title title1 = new Title("Title1");
			chart1.Titles.Add(title1);
			chart1.ChartAreas.Add(area1);
			Legend legend = new Legend();
			chart1.Legends.Add(legend);
			legend.Docking = Docking.Top;
		}
		[STAThread]
		static void Main() {
			Application.Run(new Form1());
		}
	}
}

以上。
