FYI, here's how it can be done using the existing API:

using ScottPlot;
using ScottPlot.WinForms;

namespace Sandbox.WinForms;

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        formsPlot1.Plot.Add.Signal(Generate.Sin());
        formsPlot1.Plot.Add.Signal(Generate.Cos());

        formsPlot1.Menu.Add("Open in New Window", OpenInNewWindow);
    }

    void OpenInNewWindow(IPlotControl ctrl)
    {
        FormsPlot fp = new() { Dock = DockStyle.Fill };
        fp.Reset(ctrl.Plot);

        Form form = new();
        form.Controls.Add(fp);
        form.ShowDialog();
    }
}

Good point! ❤️

I don't recall whether the avalonia control already has a standalone plot viewer. Are you interested in implementing this and creating a PR? I can merge it in quickly and plan to release a new package by the end of the weekend 🚀
