• trigger mouse enter and leave events in user controls (Improve mouse interactions in Avalonia control #1040)
• provide options for automatic axis limits to ignore axis lines and spans (add IgnoreAxisAuto field to axis lines and spans #1083)
• implement an axis crosshair label feature (Crosshair #1093)

Original Question

Your Environment

• ScottPlot Version: 4.1.12 beta
• Operating System: Win10 20H2
• Is it a GUI app? What platform? WinForms
• .Net: net472 and net5.0-windows was checked.

Simple Mdi Winforms app. Child form with only formsPlot1 on it. MouseLeave and MouseEnter not working, MouseMove is working.

This is critical to implement some info on MouseMove (to hide it after we leave the plot).

P.s. Related question:
How to properly implement axes cursor on MouseMove with ScottPlot?

I was tring something like this:

private void formsPlot1_MouseMove(object sender, MouseEventArgs e)
{
    (double x, double y) = formsPlot1.GetMouseCoordinates();
    _HLine.Y = y;
    _HLine.IsVisible = true;
    _VLine.X = x;
    _VLine.IsVisible = true;
    formsPlot1.Render(skipIfCurrentlyRendering: true);
}

And it's worked BUT. Because of _HLine and _VLine are plots, ScottPlot autozoom and autoaxes always trying to consider their values. And this lead to whole wrong behavior. For example:

Cursors must be completely excluded from plotting logic.

Also, is it possible to display Cursor coordinates on the axes (red circles on screen above)?
