c# - チャート コントロール C# を使用してデータを表示する

Question

CSV ファイルからデータが取り込まれる datagridview があります。ここで、テーブル内のデータを表現したいと思います。いくつかのコードを試しましたが、うまくいきません。ボタンが押された後、チャートを描画したい。

ここに私のコード全体があります：

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        public class HRData
        {
            public int? HeartRate { get; set; }
            public int? Speed { get; set; }
            public int? Power { get; set; }
            public int? Altitude { get; set; }

            public override string ToString()
            {
                return String.Format("Heart rate={0}, Speed={1}, Power={2}, Altitude={3}", HeartRate, Speed, Power, Altitude);
            }
        }   

        public static class HRDataReader
        {
            static private int? ConvertValue(string[] values, int index)
            {
                if (index >= values.Length)
                    return null;
                int value;
                if (int.TryParse(values[index], out value))
                    return value;
                return null;
            }

            static public IList<HRData> Read(string fileName)
            {
                if (string.IsNullOrEmpty(fileName))
                    throw new ArgumentNullException("fileName");

                using (StreamReader sr = new StreamReader(fileName))
                {
                    string line;

                    // First: Skip to the correct section.
                    while ((line = sr.ReadLine()) != null)
                        if (line == "[HRData]")
                            break;

                    // Now: Read the HRData
                    List<HRData> data = new List<HRData>();
                    while ((line = sr.ReadLine()) != null)
                    {
                        if (line.StartsWith("[") && line.EndsWith("]"))
                            break;
                        line = line.Trim().Replace("\t", " "); // Remove all tabs.
                        while (line.Contains("  ")) // Remove all duplicate spaces.
                        line = line.Replace("  ", " ");
                        string[] values = line.Split(' '); // Split the line up.
                        data.Add(new HRData
                        {
                            HeartRate = ConvertValue(values, 0),
                            Speed = ConvertValue(values, 1),
                            Power = ConvertValue(values, 2),
                            Altitude = ConvertValue(values, 3)
                        });
                    }
                    return data;
                }
            }
