This scale is used with the LinearGaugeControl. It is represented by an instance of the LinearScale class. It can be accessed as an item of the LinearScaleCollection object returned by the LinearGaugeControl.Scales property.
A Linear Scale consists of Tickmarks, Labels, Custom Labels, ranges, Layers. It also uses the following Value Indicators: a Level Bar, markers and range bars.
A typical Linear Scale is shown in the image below:
Example
This example illustrates how to create a LinearGaugeControl instance with two LinearScale objects.
