Remarks

Arc scale is intended to be used with the CircularGauge. 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 CircularGauge.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.

Example

The following example demonstrates how to create a Circular Gauge with two needles, three ranges, one marker and one range bar.
