How to mix high-performance and standard versions in a series?
When I use GLineSeries to draw lines and at the same time use ScatterSeries for markers, it shows a null reference exception.
Because the PointGeometry of the high-performance version of GScatterSeries does not inherit from Microsoft's controls, I cannot add data binding and mouse events to it. I hope that each point, as a marker, can respond to mouse events independently.

Forgot to mention, I use WPF for development, and my development environment is .NET Framework 4.8.
