Properties

Child

Gets or sets the child content of a BarPointer.

Declaration
public View Child { get; set; }
Property Value
Type Description
Microsoft.Maui.Controls.View

The default value is null.
Examples
 <gauge:SfLinearGauge>
    <gauge:SfLinearGauge.BarPointers>
        <gauge:BarPointer Value="50" Position="Outside" PointerSize="50" Offset="10" 
                          CornerStyle="BothCurve">

    </gauge:SfLinearGauge.BarPointers>
</gauge:SfLinearGauge>

CornerStyle

Gets or sets a CornerStyle enumeration value that describes the corner/edge style of the BarPointer.

Declaration
public CornerStyle CornerStyle { get; set; }
Property Value
Type Description
CornerStyle

A value of the enumeration. The default is BothFlat.
Examples
 <gauge:SfLinearGauge>
    <gauge:SfLinearGauge.BarPointers>
        <gauge:BarPointer Value="50" Position="Outside"  CornerStyle="BothCurve" />
