The Marker is a scale indicator that points to a value along a scale. It is a small shape that can be located around the scale bar. To add marker to the scale you have to include Marker element to the list of the scale indicators:

<telerik:RadRadialGauge Width="200" Height="200" telerik:StyleManager.Theme="Windows8"> 
            <telerik:Marker Value="80" telerik:ScaleObject.Location="Outside"/> 

The Marker supports the following features:

  1. Layout

  2. You can set location of the Marker relative to a scale bar using a telerik:ScaleObject.Location property. For example, "Outside"

    WPF RadGauge RadialScale Marker Location Outside


    WPF RadGauge RadialScale Marker Location Inside

    or "OverCenter"

    WPF RadGauge RadialScale Marker Location OverCenter

  3. telerik:ScaleObject.Offset relative to a scale bar.

  4. telerik:ScaleObject.RelativeHeight that specifies a height of the Marker given as part of the container size.

  5. telerik:ScaleObject.RelativeWidth that specifies a width of the Marker given as part of the container size.

  6. The standard Telerik provided Marker templates allow to use the BorderBrush and the BorderThickness properties to drawing a border.

    The left of BorderThickness property is applied for the border around a Marker. Styles provided by Telerik allow using of the most popular form of Markers. You can change template of the Marker to setup desirable appearance.
