Gauge with Bands
Gauge charts are great for representing where the value falls in a range. They are especially useful in a live data scenarios like in this demo. We can also add bands on the gauge to make the value even more readable at a glance.
Key implementation details
We add bands to a gauge chart using the axis range feature of amCharts. Setting up these ranges on the axis is all you need to do to enable the bands. The chart engine takes care of the rest.
