I'm migrating to dashboard 2 and can't figure out how to get the Water Tank gauge to display the gallons value like I have in the dashboard 1 version. I'm passing the actual gallons and the gauge displays a percentage value based on the maximum range.
I found a very brief paragraph the mentions overriding CSS, but I'm lost as how to override the default percentage display with the actual numeric value and units.
The following are mentioned but I couldn't find any examples on how to implement them.
.nrdb-ui-gauge-value span - The value in the middle of the gauge
.nrdb-ui-gauge-value label - The unit label
If the water level is 95 Gallons, that is what I would like displayed instead of the percentage equivalent.
