How a gauge works at runtime

A gauge’s needle moves around the dial to reflect the value of the Value connection at the data source. If you set the sweep style to Fill (in the General tab), the color of the dial behind the needle fills as the needle moves.

The gauge’s behavior at runtime also depends on how you set up thresholds and controls.

Using thresholds

If you set up thresholds for the gauge, when the value of the Value connection is at or above the threshold value, the color of the fill changes (if you set up different fill colors for thresholds in the Display tab). You can also configure the section of the gauge at or above the threshold level to blink.

Using controls

If you do not assign the Value connection, the gauge displays the minimum value.

Opening graphic displays

When you open a display at runtime, the application reads the value of the Value connection and updates the gauge based on the value.
