Had the same issue and solved by deleting derived data.

That I know, as mentioned in my OP. That is not the issue though.

Thanks for the idea Claude31, it kind of works to negate the number. The lowest numbers are now top to bottom, but I also have a gradient that now appears on the wrong side of the linke marks.

Thank for looking into this darkpaw. The final design will include a number inside the circle, and the default opacity would make the text more difficult to read. I will continue to play around with this and hopefully I will find a solution- I will post it here if I find something. Thanks again for the help.

Ok, I need to add a post-it note to my monitor "in SwiftUI- order matters". It will work as expected if the order of LineMark and AreaMark is swapped. Chart { ForEach(rankings) { element in AreaMark(...) LineMark(...) } }

You can also set the Visibility directly: Chart{     BarMark(x: .value("o", 5),             y: .value("m", "Duration: 5m"),             width: 7)         .foregroundStyle(.orange)          BarMark(x: .value("o", 7),             y: .value("m", "Intervals: 7"),             width: 7)         .foregroundStyle(.teal) } .chartYAxis(.hidden) .chartXAxis(.hidden)

Having the same issue now that I build the app with iOS 14.5. I will use the work-around mentioned by apoorvet (thanks!), but this is surely a bug right?
