You’ve commented out the style inclue: https://github.com/LyubomiRadev/PieChart/blob/master/AvaloniaApplication1/App.axaml#L9C8-L9C110 Without the styles, the PlotView won’t have a visual presence.

The documentation is pretty patchy, and none of it applies to the Avalonia provision.

You are using compiled bindings, and then using an annoumous type as your data-context: this is asking for trouble. It seems to work fine if you replace it with this.DataContext = this

https://github.com/LyubomiRadev/PieChart/blob/master/AvaloniaApplication1/Views/MainWindow.axaml.cs#L40

Then it will match the declared type

https://github.com/LyubomiRadev/PieChart/blob/master/AvaloniaApplication1/Views/MainWindow.axaml#L10

Oh yes, that’s the old one. With Avalonia11 you need this style include: <StyleInclude Source="avares://OxyPlot.Avalonia/Themes/Default.axaml"/>

The line in the csproj is wrong: it should be

<PackageReference Include="OxyPlot.Avalonia" Version="2.1.0-Avalonia11" />

https://github.com/LyubomiRadev/PieChart/blob/master/AvaloniaApplication1/AvaloniaApplication1.csproj#L21C5-L21C68

This should be referencing version 2.1.0-Avalonia11 because you are using Avalonia 11 (per https://github.com/LyubomiRadev/PieChart/blob/master/Directory.Build.props#L4 )
