        private Form2 form2 = new Form2();


        private void button2_Click(object sender, EventArgs e)
        {
            Form2 frm2 = new Form2();
            frm2.Show();

            this.chart1.Series["Speed"].Points.AddXY("James", "90");
            this.chart1.Series["Speed"].Points.AddXY("John", "18");
            this.chart1.Series["Speed"].Points.AddXY("Carl", "83");

You should write a new constructor in Form2 and get values (that you need to draw the chart) as parameters. Like this :

private void Form2_Load(object sender, EventArgs e)
{
    public Form2()
    {
       InitializeComponent();
    }

    public Form2(**PARAMETERS**) : this()
    {
       // Do what you want with your data!
    }
}

Now pass the data to Form2 in Form1 :

Form2 frm2 = new Form2(**PARAMETERS**);
frm2.Show();

You can use events from Form1 and subscribe it in Form2
