Gauges

You can also create gauges with the PieChart control, the library provides the GaugeGenerator class, it is a helper class that builds a collection of PieSeries<ObservableValue> based on the properties we specify, this documentation contains multiple gauges samples, [here you can find the basic gauge sample](https://livecharts.dev/docs/{{ platform }}/{{ version }}/samples.pies.gauge1).

The GaugeGenerator.BuildSolidGauge() function, takes one or multiple GaugeItem instances as parameters, a GaugeItem instance represents an element in our gauge, the constructor of the GaugeItem class takes 2 arguments:

• value: the gauge value of type double.
• builder: a delegate where we can configure the assigned series to the value, we can here set the color, the labels size and customize every property as a regular [pie series](https://livecharts.dev/docs/{{ platform }}/{{ version }}/PieChart.Pie%20series).

You can find an example that uses both parameters in the [slim gauge sample](https://livecharts.dev/docs/{{ platform }}/{{ version }}/samples.pies.gauge4).

Finally, there is a special value to customize the background series of a gauge, using the GaugeItem.Background as the value in the GaugeItem class, will create a series behind our gauge values that will behave as the background in our plot, [here is an example](https://livecharts.dev/docs/{{ platform }}/{{ version }}/samples.pies.gauge2) that uses this feature.
