Installation and first chart

Create a new Avalonia project and name the project and the solution AvaloniaSample, and select .NET 6.0 as the framework, if the framework is not available for you, you can also use .NET 5.0, .NET core 3.1 or .NET 4.6.2 or greater, if you need help to get started with Avalonia please see the Avalonia docs.

Install from NuGet

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

LiveChartsCore.SkiaSharpView.Avalonia

Create a View Model

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

using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;

namespace AvaloniaSample
{
    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.axaml 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="MyApp"
    xmlns="https://github.com/avaloniaui"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:AvaloniaSample"
    xmlns:lvc="using:LiveChartsCore.SkiaSharpView.Avalonia">

    <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.axaml.cs file, then add the settings you need:

using Avalonia;
using Avalonia.Controls.ApplicationLifetimes;
using Avalonia.Markup.Xaml;
using LiveChartsCore;// mark
using LiveChartsCore.SkiaSharpView;// mark

namespace AvaloniaSample
{
    public class App : Application
    {
        public override void Initialize()
        {
            AvaloniaXamlLoader.Load(this);

            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
                );
        }

        public override void OnFrameworkInitializationCompleted()
        {
            if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
            {
                desktop.MainWindow = new MainWindow();
            }

            base.OnFrameworkInitializationCompleted();
        }
    }
}
