Hi malkarra,

You can easily convert a DateTime value to a double using Microsoft .NET Framework's methods as shown here:

Code: Select all

    private void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
      int x = line1.CalcXPosValue(Convert.ToDouble(line1.XValues[5]));
      int y = line1.CalcYPosValue(line1.YValues[5]);
      tChart1.Graphics3D.TextOut(x,y,"My Text");
    }
