Each linear scale can hold a collection of markers returned by the LinearScale.Markers property and represented by the LinearScaleMarkerCollection class. Each collection item is an instance of the LinearScaleMarker class and can be accessed via the GaugeDependencyObjectCollectionBase<T>.Item property of a LinearScaleMarkerCollection object.
For more information on markers, refer to the Marker (Linear Scale) document.
Example
This example illustrates how to create a LinearGaugeControl instance with two LinearScale objects.
