Installation and first chart

Open visual studio 2022, select "Create a new project", then select the Blank App, Packed with WAP (WinUI 3 In Desktop) template.

Name the project and the solution WinUISample, and use the default target version.

Install from NuGet

Now install LiveCharts from NuGet. If you need more help to install a package from NuGet, please follow this guide.

LiveChartsCore.SkiaSharpView.WinUI

Create a View Model

After the package is installed add a new class to your project as follows:

using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;

namespace WinUISample
{
    public class ViewModel
    {
        public <ISeries[] Series { get; set; } 
            = new ISeries[]
            {
                new LineSeries<double>
                {
                    Values = new double[] { 2, 1, 3, 5, 3, 4, 6 },
                    Fill = null
                }
            };
    }
}

Add the chart control to the UI

Finally go to the MainWindow.xaml file and add the LiveCharts namespace, don't forget to add also the namespace of your ViewModel class, then add a CartesianChart control and bind the Series property:

<!-- mark -skip 3 -take 2 -->
<Window x:Class="WinUISample.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:local="using:App3"
    xmlns:lvc="using:LiveChartsCore.SkiaSharpView.WinUI">

    <Window.DataContext>
        <local:ViewModel /><!-- mark -->
    </Window.DataContext>

    <lvc:CartesianChart<!-- mark -->
        Series="{Binding Series}"><!-- mark -->
    </lvc:CartesianChart><!-- mark -->

</Window>

And that's it, start your application and you will see the chart in your main window.

Configure themes and mappers (Optional)

Optionally you could configure LiveCharts to add a theme or a custom mapper, add the following code when your application starts:

Go to the Solution Explorer and browse for App.xaml.cs file, then edit the it as follows.

using Microsoft.UI.Xaml;
using LiveChartsCore;// mark
using LiveChartsCore.SkiaSharpView;// mark

// and more about our project templates, see: http://aka.ms/winui-project-info.

namespace App5
{
    /// <summary>
    /// Provides application-specific behavior to supplement the default Application class.
    /// </summary>
    public partial class App : Application
    {
        /// <summary>
        /// Initializes the singleton application object.  This is the first line of authored code
        /// executed, and as such is the logical equivalent of main() or WinMain().
        /// </summary>
        public App()
        {
            this.InitializeComponent();
        }

        /// <summary>
        /// Invoked when the application is launched normally by the end user.  Other entry points
        /// will be used such as when the application is launched to open a specific file.
        /// </summary>
        /// <param name="args">Details about the launch request and process.</param>
        protected override void OnLaunched(Microsoft.UI.Xaml.LaunchActivatedEventArgs args)
        {
            m_window = new MainWindow();
            m_window.Activate();

            LiveCharts.Configure(config =>// mark
                config// mark
                    // registers SkiaSharp as the library backend
                    // REQUIRED unless you build your own
                    .AddSkiaSharp()// mark

                    // adds the default supported types
                    // OPTIONAL but highly recommend
                    .AddDefaultMappers()// mark

                    // select a theme, default is Light
                    // OPTIONAL
                    //.AddDarkTheme()
                    .AddLightTheme()// mark

                    // finally register your own mappers
                    // you can learn more about mappers at:
                    // ToDo add website link...
                    .HasMap<City>((city, point) =>// mark
                    {// mark
                        point.PrimaryValue = city.Population;// mark
                        point.SecondaryValue = point.Context.Index;// mark
                    })// mark
                    // .HasMap<Foo>( .... )// mark
                    // .HasMap<Bar>( .... )// mark
                );// mark
        }

        private Window m_window;
    }
