@Christoph-Hart This is still a problem so I open an issue:
https://github.com/christophhart/HISE/issues/685
Display Buffer case:
createPath from a goniometer Display Buffer returns an oscilloscope
FloatingTile case:
If you want to use a FloatingTile, drawAnalyserPath doesn't overwrite the LAF for goniometers (but drawAnalyserBackground and drawAnalyserGrid do work)
So in the end, no solution would allow you to LAF a goniometer properly
