Implementing scroll bar along x-axis

Question

I am trying to implement scroll bar along x-axis, but i failed , can any one help please......This is my code:

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        Chart chart2 = new Chart();
        Chart chart3 = new Chart();
        int[] rand;
        int[] rand1;
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
    {

        chart2.Width = 1000 ;
        chart2.Height = 200;
        this.Controls.Add(chart2);
        this.Controls.Add(chart3);

        chart2.MouseMove += new MouseEventHandler(chart2_MouseMove);
       //chart2.GetToolTipText += new EventHandler<ToolTipEventArgs>(chart2_GetToolTipText);

        chart2.ChartAreas.Add("Area");
