The following document describes what a scale is, what kinds of scales are present in Gauges and also how scales can be used.

A Scale is a key element of a Gauge control. It displays static items as labels, tickmarks, ranges and other elements that visually represent a Gauge control and its appearance; and also contains dynamic gauge elements used to indicate current values of a variable data (so-called Value Indicators).

There are two types of scales, each compatible with its specific Gauge control.
