Assuming you are using the Microsoft .NET charting component, you may use this code:

C#

private void button1_Click(object sender, EventArgs e)
{
  SaveFileDialog dlg = new SaveFileDialog();
  if(dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    this.chart1.SaveImage(dlg.FileName, ChartImageFormat.Png);
}
