Gauge

An analog radial dial showing a single process value against a fixed range.

In Studio

In Studio, double-click Gauge in the Components category of the Components panel. It is added to the open view, where you can drag it into place.

When to use

Use Gauge for a single current reading where the position around an arc (rather than a fill bar) is the more familiar instrument metaphor — a pressure, a speed, an RPM.

Properties

Property	Type	Default	Description
Value	String	(none)	The bound process value the needle arc reflects.
Label	String	Gauge	The caption shown below the dial.
Min	Number	0	The value at the start of the arc (bottom-left).
Max	Number	100	The value at the end of the arc (bottom-right).
Unit	String	(none)	The unit text shown under the numeric readout.
Arc Color	Color	#4A6B8A	The color of the filled portion of the arc. Not an HMI-palette state color — pick any color that reads against the (fixed) unfilled-arc track.

Binding

Click Bind… on the Value property and bind it to a tag or an expression to drive the live value.

This binding is read-only — the component never writes to the tag.
