# Indicator Abstract Classes

The indicator controls, derive from the **GaugeIndicator** class. Because of that they have some common functionality. This topic will list the properties of the GaugeIndicator and BarGaugeIndicator abstract classes.

## GaugeIndicator Properties

* **StartValue** (double): Determines from where in the value range does the indicator start. By default every indicator starts at 0.
* **Owner**: Gets the owner range of this indicator.
* **IsAnimated** (bool): Gets or sets the IsAnimated property value. This property enables and disables the animated transition between values.
* **AnimationDuration** (Duration): Gets or sets the duration of the animation when IsAnimated is true.
* **AnimationEasing** (EasingFunctionBase): Gets or sets the easing of the animation when IsAnimated is true.

## BarGaugeIndicator Properties

The **BarGaugeIndicator** inherits the GaugeIndicator and introduces the following properties:

* **Thickness** (double): Gets or sets the thickness of this bar indicator.
* **Brush** (Brush): Gets or sets the color of this bar indicator.
