CurrentIndex: Integer;
The CurrentIndex property returns index of the current series point.
This example describes custom method. The data series is passed by points.
Public Function UserFunc(Input: ITimeSeries): Double;
Var
i: Integer;
Begin
If Input.PointCount > 0 Then
i := Input.CurrentIndex;
Return Math.Log10(Input.Item(i));
End If;
End Function UserFunc;
The method returns the natural series logarithm.
