IModelSupported,
ILayoutCalculatorRelated API Members
The following members return ValueIndicatorBase objects:
Remarks
The ValueIndicatorBase class provides all functional capabilities common for value indicators derived from it: (e.g. ArcScaleNeedle returned by the ArcScale.Needles property, LinearScaleMarker returned by the LinearScale.Markers property, etc.).
Example
This example demonstrates how to enable the capability for end-users to change a needle’s value via a mouse click. To do this, set the ValueIndicatorBase.IsInteractive property to True as shown below.
Note that although in this example, only the ArcScaleNeedle class is used, the IsInteractive property is available in all ValueIndicatorBase class descendants, and therefore it is available in all value indicators.
