A circular gauge is commonly used to build speedometer-style dashboards by combining needles, color-coded ranges, and labeled apertures on a radial scale. Multiple gauges can be placed on a single stage for a complete instrument cluster.
This sample pairs two gauges on one stage to simulate a car dashboard. The main semicircular gauge displays speed from 0 to 220 km/h with orange (160-180) and red (180-220) warning ranges, a needle, and an aperture showing both current and average speed. A smaller half-circular gauge nested below tracks engine RPM from 0 to 9,000 with matching orange and red danger zones, trapezoidal ticks, and its own current/average aperture.
Follow the step-by-step Circular Gauge Chart Tutorial to learn how such gauges are built. See the Circular Gauge documentation for all configuration options.
