When using foregroundStyle(by: and symbol(by: with a series of data using Multi-series Line Mark and limited with a pickerView, the colour/symbol changes depending on the number of series selected and is not consistent. enum Hand {     case left, right, both } struct HandSample: Identifiable {     var hand: String    // Series     var count: Double     var date: Date     var id = UUID() }     var data: [HandSample] {         switch hand {         case .both:             return loadData(samples: samples, days: days, left: true, right: true)         case .left:             return loadData(samples: samples, days: days, left: true, right: false)         case .right:             return loadData(samples: samples, days: days, left: false, right: true)         }     }     func loadData(samples: FetchedResults<Sample>, days: Int, left: Bool, right: Bool) -> [HandSample] {         var series: Array<HandSample> = Array()         let sinceDate = Calendar.current.date(byAdding: .day, value: -days, to: Date())         for sample in samples {             if sample.sampleDate > sinceDate! {                 if left {                     let leftSamples = HandSample(hand: "Left", count: sample.left.doubleValue, date: sample.sampleDate)                     series.append(leftSamples)                 }                 if right {                     let rightSamples = HandSample(hand: "Right", count: sample.right.doubleValue, date: sample.sampleDate)                     series.append(rightSamples)                 }             }         }         return series     }     var body: some View {         VStack {             Picker ("Hand", selection: $hand.animation(.easeOut)) {                 Text("Both Hands")                     .tag(Hand.both)                 Text("Left Hand")                     .tag(Hand.left)                 Text("Right Hand")                     .tag(Hand.right)             }             .pickerStyle(.segmented)             Chart (data) {                 LineMark(                     x: .value("Date", $0.date),                     y: .value("Count", $0.count),                     series: .value("Hand", $0.hand)                 )                 .foregroundStyle(by: $0.hand)                 PointMark(                     x: .value("Date", $0.date),                     y: .value("Count", $0.count)                 )                 .foregroundStyle(by: $0.hand)                 .symbol(by: .value("Hand", $0.hand))             }         }     } In the attached sample, shows Right as a Green Cross when Both Hands series are shown, but shows Right as a Blue Circle when only the Right Hand series is shown. iOS 16 Beta 4 (20A5328h) Xcode 14.0 beta 4 (14A5284g)
