The widget shows the last received value of a signal on a gauge, whose thresholds are set by the user while adding it to a dashboard.
Minimum and maximum values are required, once they are setted is also possible to specify the danger thresholds, that represent the red bands of the gauge:
- Minimum danger band, delimited by the minimum value and the minimum danger threshold;
- Maximum danger band, delimited by the maximum danger threshold and the maximum value;
- Correct band, delimited by the minimum danger threshold and the maximum danger threshod.
Once all the values are setted and the source signal chosen, the widget is added to the dashbaord, updating at every communication.
The thresholds are editable at every moment through the edit modal of the widget. The data frequency and reference date can also be choosen (for example, Hourly Average shows the last availabe hourly average). It is also possible to show value substitution if set in the signal (substitution colors are applied if set in signals settings, even if substituted value option is not set).
