A radial gauge for PI Vision built for glanceability. The needle sweeps live while the large centre value takes the colour of the active zone, readable across the room on light or dark displays. A ghost pointer marks where the value was N minutes ago, answering 'better or worse than an hour ago?' without opening a trend. Set any arc - a classic three-quarter gauge, a compact semi-circle for headers, or a full ring for modern KPI tiles - and ticks, zones and indicators follow. Drop several tags and Multi-Ring gives each its own concentric arc with a colour-matched legend.
