Constructors

CircularPointerBase()

Initializes an instance of the class.

protected CircularPointerBase()

Properties

PointerDirection

Gets or sets the direction the pointer will rotate on value changes. This is a dependency property.

public CircularPointerDirection PointerDirection { get; set; }

Property Value

CircularPointerDirection:

The direction the pointer will rotate on value changes. The default value is CircularPointerDirection.Normal.

Radius

Gets the associated radius of this element, which is inherited/set via an attached property on CircularScale.

protected double Radius { get; }

Property Value

double:

The radius.

ScaleBarExtent

Gets the extent of the bar in the associated ScaleBase.

protected double ScaleBarExtent { get; }

Property Value

double:

The extent of the bar.

StartAngle

Gets the associated start angle of this element, which is inherited/set via an attached property on CircularScale.

protected double StartAngle { get; }

Property Value

double:

The start angle.

SweepAngle

Gets the associated sweep angle of this element, which is inherited/set via an attached property on CircularScale.

protected double SweepAngle { get; }

Property Value

double:

The sweep angle.

ValueAngle

Gets or sets the angle used to display the Value on the circular gauge. This is a dependency property.

protected double ValueAngle { get; set; }

Property Value

double:

The value angle. The default value is 0.
