Line
A Line indicates the whole interval along the tickmarks on the scale and is used for decoration purposes. Usually, a Line is placed under tickmarks, but you can change its position by using the ScaleLineOptions.Offset property.

A Line is defined by an instance of the ScaleLineOptions class returned by the Scale.LineOptions property.
