Hi Kevin,
You'll need to change the state indicator value as well as the indicator value so that it triggers a state change when the value goes outside the gauge axis range. Check out the Gauges Gallery \ Gauges \ Indicators \ State Indicators example.

When a gauge value is outside the displayed range, the indicator appears either at the minimum or maximum, as appropriate.
Is there a simple way to indicate that the value is off the scale?
I have set the tooltip and I could also display a label showing the value.
I also tried adding a couple of state indicators at the range extremes, but the logic seems to work on the value shown on the gauge, not the actual indicator value.
Thanks
Kevin
