Remarks
A marker is used to indicate an invariable value of a linear scale. An instance of a linear scale marker is represented by the LinearScaleMarker
object. It can be accessed as an item of the LinearScaleMarkerCollection object returned by the LinearScale.Markers property.
A typical marker of a linear scale is shown in the image below:
For more information on markers, refer to the Marker document.
Example
This example illustrates how to create a LinearGaugeControl instance with two LinearScale objects.
