Chart2.ChartAreas.Add("Series 1");
// create a couple of series
Chart2.Series.Add("Series 1");
Chart2.Series.Add("Series 2");
// add points to series 1
foreach (int value in (List<int>)ViewData["Chart"])
{
Chart2.Series["Series 1"].Points.AddY(value);
}
// add points to series 2
foreach (int value in (List<int>)ViewData["Chart"])

Chart2.BorderlineDashStyle = ChartDashStyle.Solid;
Chart2.BorderWidth = 2;
