'Declaration Public Property LabelPosition As DataLabelPosition
public DataLabelPosition LabelPosition {get; set;}
When this property is set to Custom, the position is determined by the values of the Left and Top properties.
When a custom label position is assigned, connecting lines appear between the label and its respective DataPoint. These lines are referred to as 'leader lines'; use the Series.LeaderLines property to control their appearance.
Note that leader lines can be hidden by setting the SeriesDataLabels.ShowLeaderLines property to false.
