Inherits Scale
The following members return ArcScale objects:
Arc scale is intended to be used with the CircularGaugeControl. An instance of an arc scale is represented by the ArcScale object. It can be accessed as an item of the ArcScaleCollection object returned by the CircularGaugeControl.Scales property.
An Arc Scale consists of tickmarks, labels, custom labels, ranges, layers and a spindle cap. As value indicators, it can use needles, markers and range bars.
A typical Arc Scale is shown in the image below:
This example illustrates how to create a CircularGaugeControl instance with a single ArcScale object.
