Thanks for the clarification @mikeKuester! I'll adapt this issue to track progress toward adding a "legend panel" that allows a legend to be displayed inside the control, but outside the data area.

For now, below is the recommended way to achieve this goal, and I'll add this demo to the demo app:

using ScottPlot;
using ScottPlot.Extensions;

namespace WinForms_Demo.Demos;

public partial class LegendOutsideBitmap : Form, IDemoWindow
{
    public string Title => "Legend Outside the Plot (Bitmap)";

    public string Description => "Demonstrates how to display the " +
        "legend outside the plot by obtaining it as a Bitmap and " +
        "displaying it outside the plot control anywhere in your window.";

    public LegendOutsideBitmap()
    {
        InitializeComponent();

        int count = 20;
        for (int i = 0; i < 20; i++)
        {
            double[] ys = Generate.Sin(100, phase: i / (2.0 * count));
            var sig = formsPlot1.Plot.Add.Signal(ys);
            sig.Color = Colors.Category20[i];
            sig.LineWidth = 2;
            sig.Label = $"Line #{i + 1}";
        }

        formsPlot1.Plot.Legend.OutlineStyle.Width = 0;
        formsPlot1.Plot.Legend.BackgroundFill.Color = SystemColors.Control.ToColor();
        ScottPlot.Image legendImage = formsPlot1.Plot.GetLegendImage();
        byte[] legendBitmapBytes = legendImage.GetImageBytes(ImageFormat.Bmp);
        MemoryStream ms = new(legendBitmapBytes);
        Bitmap bmp = new(ms);
        pictureBox1.Image = bmp;
        pictureBox1.SizeMode = PictureBoxSizeMode.CenterImage;
        pictureBox1.BackColor = SystemColors.Control;
    }
}
