Constructors

MarkerPointer()

Declaration
protected MarkerPointer()

Fields

MarkerOffsetProperty

Identifies the MarkerOffset dependency property.

Declaration
public static readonly DependencyProperty MarkerOffsetProperty
Field Value
Type Description
Microsoft.UI.Xaml.DependencyProperty

The identifier for MarkerOffset dependency property.

OffsetUnitProperty

Identifies the OffsetUnit dependency property.

Declaration
public static readonly DependencyProperty OffsetUnitProperty
Field Value
Type Description
Microsoft.UI.Xaml.DependencyProperty

The identifier for OffsetUnit dependency property.

Properties

MarkerOffset

Gets or sets a value that specifies the marker position value either in logical pixel or radius factor.

Declaration
public double MarkerOffset { get; set; }
Property Value
Type Description
System.Double

It defines the position offset of the marker either pixel or factor. The default value is double.NaN.
Examples

If OffsetUnit is Factor, value will be given from 0 to 1. Here pointer placing position is calculated by MarkerOffset * axis radius value. Example: MarkerOffset value is 0.2 and axis radius is 100, pointer is moving 20(0.2 * 100) logical pixels from axis outer radius. If OffsetUnit is Pixel, defined value distance pointer will move from the outer radius axis. When you specify MarkerOffset is negative, the pointer will be positioned outside the axis.

OffsetUnit

Gets or sets the value that indicates to calculate the marker pointer offset in logical pixel or radius factor.

Declaration
public SizeUnit OffsetUnit { get; set; }
Property Value
Type Description
SizeUnit

One of the SizeUnit enumeration that specifies how the MarkerOffset value is considered. The default mode is Pixel.
