Gauge · Unknown measurement
The dial remains without inventing a pointer or a zero.
Use a gauge for one current measurement with a meaningful minimum and maximum. Avoid a gauge when a trend or several values are the real question.
One stable measurement is projected within its range. The planner owns the scale and limits; the native adapter renders the supplied geometry and selected value.
Choose a concise title, units and colour. Keep range meaning visible in the description and exact values available outside the graphic.
