Issue to be solved:
Supporting Avalonia would allow interactive plots on Linux and Mac. If you're not familiar, Avalonia feels very similar to WPF, but with a few features absent. Avalonia is in pre-release, so that could well change.

I have a branch on my fork with a working Avalonia UserControl. Because of the aforementioned absent features, as well as the interest in cross-platform compatibility, not all the same features that WPF and WinForms enjoy are present.

The branch is available here: https://github.com/Benny121221/ScottPlot/tree/avalonia

I can understand that you may be hesitant to support another platform, but I personally believe there is merit in being available on Linux and Mac. Plus, Avalonia feels very similar to WPF, most code can be copy-pasted and then find-and-replaced.

Let me know if you want me to open a PR. If you don't want to enhance your maintenance burden, then I'm happy to release an unofficial Avalonia UserControl, as I have a personal need for Linux support.
