Gauge Types

Use the gauge classes to create gauges that display metrics in several common formats, including status meters, LEDs, and ratings.

Three gauge classes are available: LEDGauge, RatingGaugeChart, and StatusMeterGauge. Each of these gauges must be implemented and instantiated as a different class.

Of these gauge types, the LEDGauge and StatusMeterGauge classes share many common characteristics, including the methods you can invoke and the properties you can set. While rating gauges share some characteristics with the other gauge types, the RatingGaugeChart class and supporting classes are described separately within this topic.

The following examples use the same value, 54.5, as the gauge metric. In addition, an instance of the Threshold class is used to specify the color shading on the dial gauge and the status meter gauge, as well as the color of the LED.
