Leader lines connect data labels to their respective data points.
The LeaderLines property provides a way to customize the appearance of the connecting lines. These lines are only drawn, however, for data labels whose DataLabel.LabelPosition property is set to Custom.
Use this property to allow leader lines to be shown using the default appearance, i.e., setting this property to true without specifying a custom appearance causes them to acquire the default appearance as determined by Excel.
Leader lines can be hidden by setting this property to false.
