Perspective - Simple Gauge

Component Palette Icon:

The Simple Gauge component in Perspective provides a way to show realtime values in a range as they change. This gauge is a less complicated version of the Gauge component. It has just one axis, is easy to configure and is customizable in its appearance.

New in 8.1.2

The Simple Gauge component has three pre-configured variants:

• Half Circle - Default layout with a half-circle gauge.
• 3/4 Circle - Layout with a 3/4 circle gauge.
• Full Axis - Layout with a full axis gauge.

Component Events

The Perspective Event Types Reference page describes all the possible component event types for Perspective components. Not all component events support each Perspective component. The Component Events and Actions page shows how to configure events and actions on a Perspective component. Component scripting is handled separately and can be accessed from the Component menubar or by right clicking on the component.
