サンプルコード

using System;
using System.Windows.Forms;
using System.Drawing;
using System.Windows.Forms.DataVisualization.Charting;

namespace App
{
	public partial class Form1: Form {
		public Form1() {
			this.Size = new Size(600, 400);
			this.Text = "sin";
			Chart chart1 = new Chart();
			chart1.ChartAreas.Clear();
			chart1.Series.Clear();
			chart1.Legends.Clear();
			chart1.Dock = DockStyle.Fill;
			chart1.ChartAreas.Add(new ChartArea());
			ChartArea chartArea = chart1.ChartAreas[0];
			chartArea.AxisX.IsMarginVisible = false;
			chartArea.AxisY.IsMarginVisible = false;
			chartArea.CursorX.IsUserSelectionEnabled = true;
			chartArea.CursorY.IsUserSelectionEnabled = true;
			chartArea.CursorX.Interval = 0;
			chartArea.CursorY.Interval = 0;
			chartArea.InnerPlotPosition.Auto = false;
			chartArea.InnerPlotPosition.X = 8.0f;
			chartArea.InnerPlotPosition.Y = 4.0f;
			chartArea.InnerPlotPosition.Width = 84.0f;
			chartArea.InnerPlotPosition.Height = 84.0f;
			this.Controls.Add(chart1);
			Series series = new Series {
				Color = Color.Blue,
				MarkerColor = Color.Blue,
				MarkerSize = 7,
				MarkerStyle = MarkerStyle.Circle,
				ChartType = SeriesChartType.Line
			};
			for (double i = 0; i < 720; i++)
			{
				double v = Math.Sin(i / 360 * 3.14 * 2);
				series.Points.AddXY(i, v);
			}
			chart1.Series.Add(series);
		}
		static void Main() {
			Application.Run(new Form1());
		}
	}
}

以上。
