Scales

RadGauge supports multiple GaugeScale objects. The scale has range and a set of indicators that are rendered according to the scale's range.

Indicators

GaugeIndicator is a visual element that points to or visualizes a range of values on a scale. Multiple indicators can be added to a scale. Indicators can be animated when their value is changed.

Angular directives

When using the RadGauge with Angular you are going to work with multiple custom angular RadGauge specific directives. In short these directives are used by the angular framework to enable 'linking' between separate HTML tags into one 'complex' element.
