There is a ChangeValue event that occurs as the user is moving the point:

Private Sub ChartFX1_ChangeValue(ByVal dValue As Double, ByVal nSerie As

Integer, ByVal nPoint As Long, nRes As Integer)

    If ChartFX1.CurrentAxis = AXIS_X Then

        ' X axis is changing

        nRes = 1 - AdjustTime        ' AdjustTime is a checkbox, so: nRes =

1 to not allow x change

    Else ' Y axis is changing

        nRes = 1 - AdjustAmplitude

    End If

End Sub
