Constructors
CircularPointerBase()
Initializes an instance of the class.
protected CircularPointerBase()Properties
PointerDirection
The direction the pointer will rotate on value changes.
public CircularPointerDirection PointerDirection { get; set; }Property Value
- CircularPointerDirection:
The default value is Normal.
Radius
The associated radius of this element, which is inherited/set via an attached property on CircularScale.
ScaleBarExtent
The extent of the bar in the associated ScaleBase.
StartAngle
The associated start angle of this element, which is inherited/set via an attached property on CircularScale.
SweepAngle
The associated sweep angle of this element, which is inherited/set via an attached property on CircularScale.
ValueAngle
The angle used to display the Value on the circular gauge.
Methods
CalculateAngle(double)
