Remarks
A level bar is used to show the current value of a linear scale. It looks like a typical thermometer’s indicator. An instance of a linear scale level bar is represented by the LinearScaleLevelBar object. It can be accessed as an item of the LinearScaleLevelBarCollection object returned by the LinearScale.LevelBars property.
A typical level bar is shown in the image below:
For more information on level bars, refer to the Level Bar document.
Example
This example illustrates how to create a LinearGaugeControl instance with two LinearScale objects.
