Description
The AddRealTime method adds new points to a FastLineSeries. It is quicker than any of the other Add methods as only the new point is painted. AddRealTime should be used for high performance Charts.</sup>

^{Example [Visual Basic]:}

^{Dim t As Integer}

^{Private Sub Form_Load()}

^{With TChart1}

^{.AddSeries scFastLine}

^{.TimerEnabled = True}

^{.TimerInterval = 100}

^{End With}

^{End Sub}

^{Private Sub TChart1_OnTimer()}

^{t = t + 1}

^{TChart1.Series(0).asFastLine.AddRealTime t, Cos(t), "", clTeeColor}

^{End Sub}
