The resolution is to specify the colours and symbols explicitly: .chartForegroundStyleScale(["Left" : .blue, "Right" : .green]) .chartSymbolScale(["Left" : .circle, "Right" : .cross])

Problem remains on iOS 16.0 Beta 8 (20A5358a).

The issue still occurs with iOS 16 Beta 7 (20A5356a) and Xcode 14.0 beta 6 (14A5294g). Unresolved, but can't unmark it.
