Hi. I have a chart and I only want to display the chartYAxis if the phone is in portrait mode. If in landscape mode i'd like to display the chartYAxis. Any idea how I can do this?

@flaneur's design doesn't quite fit their requirements:

It seems to me that you want one view that fits in a horizontal orientation, and another view that fits in a vertical orientation. Hmmmm, if only SwiftUI offered a view that fits option!

struct DemonstrateViewThatFits: View {
    var body: some View {
        // Let SwiftUI pick!
        // Which one fits best when iPhone is horizontal?
        ViewThatFits(in: .horizontal) {
            HorizontalDesign(backgroundColor: .teal)
            VerticalDesign()
        }
    }
}

struct HorizontalDesign: View {
    var backgroundColor: Color = .indigo
    var body: some View {
        ZStack {
            backgroundColor.ignoresSafeArea()
            HStack(spacing: 10) {
                Image(systemName: "arrowshape.left").rotationEffect(.degrees(90))
                Text("Lift Controls").fontWeight(.heavy)
                Image(systemName: "arrowshape.left").rotationEffect(.degrees(-90))
            }
            .foregroundColor(.white)
            .frame(width: 700)  // <- Large number to make this NOT fit in a vertical mode
        }
    }
}

struct VerticalDesign: View {
    var backgroundColor = Color.yellow
    var body: some View {
        ZStack {
            backgroundColor.ignoresSafeArea()
            VStack(spacing: 10) {
                Image(systemName: "arrowshape.left").rotationEffect(.degrees(90))
                Text("Lift Controls").fontWeight(.heavy)
                Image(systemName: "arrowshape.left").rotationEffect(.degrees(-90))
            }
        }
    }
}

There are many more options. This is an over simplified example.
Google SwiftUI and ViewThatFits for more articles and videos.
