Remarks
The options provided by an ArcScaleLabelOptions instance can be accessed via the ArcScale.LabelOptions property of an ArcScale object.
To define the appearance of the arc scale labels, use the ScaleLabelOptions.ShowFirst, ScaleLabelOptions.ShowLast, ArcScaleLabelOptions.Orientation and ScaleLabelOptions.ZIndex properties.
The behavior of the labels are set by the ScaleLabelOptions.Addend, ScaleLabelOptions.Multiplier and ScaleLabelOptions.FormatString properties.
For more information on labels, refer to the Labels (Circular Scale) document.
