## AngularJS
Circular Gauge contains AngularJS support. You can add object as well as array object in the Circular Gauge. The two way binding support is given to the pointer value, minimum scale value and maximum scale value.
## Rendering the Circular Gauge
**ej-CircularGauge** is the control tag in which **ej** is tag prefix and **CircularGauge** is the control name.The following code example helps you to render **Circular Gauge**.

## Adding Scale Collection
**Scale** is an array object and you can use the inner tag for it. Object in the array collection (i.e. border) is extended with hyphen in the same tag.
