Multiple Values Gauge

This sample uses C# 13 preview features such as partial properties, it also uses features from the CommunityToolkit.Mvvm package, you can learn more about it here.

This web site wraps every sample using a ContentPage instance, but LiveCharts controls can be used inside any container.

View model

using System;
using LiveChartsCore.Kernel;

namespace ViewModelsSamples.Pies.Gauge3;

public class ViewModel
{
    public double Vanesa { get; set; } = 30;
    public double Charles { get; set; } = 50;
    public double Ana { get; set; } = 70;
    public Func<ChartPoint, string> LabelFormatter { get; set; } =
        point => $"{point.Coordinate.PrimaryValue} {point.Context.Series.Name}";
}
