A linear gauge for PI Vision that reads itself across a control room. The fill bar takes the colour of whichever zone the value is in, so state is obvious without reading a single digit. A live least-squares trend of the recent window forecasts when the value will reach your limit and shows the time-to-limit right on the gauge, turning a gauge into an early warning. Peak-hold markers keep showing how far an excursion went after the value has returned to normal - classic panel-meter behaviour, finally in PI Vision. Every tag you drop becomes its own pointer, so process value, setpoint and limits share one scale.
