An Arc Scale is the main circular gauge element on which all other elements (for example, range bars, needles, ranges) are placed.
A scale shows a range of values with tickmarks and scale labels. The arc scale’s object is an instance of the ArcScale class.
A circular gauge can contain multiple scales. The image below shows a gauge with two scales.
The following table lists the main properties that affect element behavior and appearance.
