protected void Timer1_Tick(object sender, EventArgs e)
{
   Series s = Chart1.Series["Series1"];
   //Determine the next X value
   double nextX = 1;

   if (s.Points.Count > 0)
   {
      nextX = s.Points[s.Points.Count-1].XValue+1;
   }

   //Add a new value to the Series
   Random rnd = new Random();
   s.Points.AddXY(nextX,(rnd.NextDouble() * 10)-5);

   //Remove Points on the left side after 100
   while (s.Points.Count > 100)
   {
      s.Points.RemoveAt(0);
   }

   //Set the Minimum and Maximum values for the X Axis on the Chart
   double min = s.Points[0].XValue;
   Chart1.ChartAreas[0].AxisX.Minimum = min;
   Chart1.ChartAreas[0].AxisX.Maximum = min + 100;
}
