LiveCharts2 VS Avalonia

But I think some of this stuff is already handled in Avalonia ecosystem like https://github.com/Mapsui/Mapsui, https://github.com/beto-rodriguez/LiveCharts2 and few others...

As far as Uno Platform goes, one can use components from WinUI and Windows Community Toolkit (WCT); so you have hundreds of UI components to work with out of the box, including some must-haves like Data Grid in WCT. Some bigger component vendors have put out their betas i.e. https://www.infragistics.com/products/uno-platform or https://www.syncfusion.com/blogs/post/syncfusions-first-control-for-uno-platform-charts.aspx . I do agree this 3rd party ecosystem eventually needs to get more love from bigger vendors, or other new ones will also step in - i.e. Live Charts has support for Uno Platform https://github.com/beto-rodriguez/LiveCharts2 or MapsUI https://mapsui.com/documentation/getting-started-uno.html

It is beta now, but should be ready for production soon, The library will also provide multiple ready-to-go themes and a high-performance package.

LiveCharts2 is a charting library completely written in C# and it is a full rewrite of LiveCharts, now LiveCahrts can run everywhere MAUI, Uno Platform, Avalonia, Xamarin, WPF, WinForms, WinUI, console and on the server side.

Apex charts will definitely do the job This is one alternative I found while digging yesterday: https://github.com/beto-rodriguez/LiveCharts2

Live charts is a cross platforms charting library .Net, to get started go to https://lvcharts.com and take a look at the instalation guide of your target platform the web site contains all the samples provided in this repo, docs and more.

try version 2! https://github.com/beto-rodriguez/LiveCharts2

WPF is not the best example of open source, as some components are still closed source. Though it only runs on Windows, a closed source operating system, so perhaps that is not so important.

That said, there are cross platform, open source .NET UI frameworks out there, including one that is inspired by WPF:

You might also want to look at AvaloniaUI[0] for a cross platform .NET GUI library. It is similar to WPF but much nicer to work with.

Production user here. There's no money gotchas. They're above reproach. In fact, I've received considerable free support from their devs on GitHub Issues [1].

The Avalonia business model is based on selling XPF, which runs WPF (Windows-only) apps on other platforms. That's very interesting to big corps with existing codebases.

Yes, but the portable GUI frameworks by Microsoft themselves are generally not very good, and they tend to be abandoned after a couple of years.

Avalonia is developed outside of the Microsoft corporate madness and seems to be slowly becoming the defacto cross-platform framework because it is expected to last a bit longer than a manager's attention span: https://avaloniaui.net/

Not my comment, but relevant here "The problem with compiling Skia to WASM is you'll lose any benefits of hardware graphics acceleration on the device."

(From https://github.com/AvaloniaUI/Avalonia/discussions/6831#disc... )

It's a bit of a hit and miss as of today. CLI, back-end and natively compiled libraries (think dll/so/dylib or even .lib/.a - you can statically link NAOT binaries into other "unmanaged" code) work best, GUI - requires more work.

Avalonia[0] and MAUI[1] have known working templates with it, but YMMV.
