Hi, I'm making use of iOS17 Charts and getting data from Core Data. Chart { ForEach(weightContext, id: \.timestamp) { series in LineMark( x: .value("Day", series.timestamp!, unit: .day), y: .value("Measurement", WeightFunctions.weightConversions(weightValue: series.value, metric: selectedWeight)) ) PointMark( x: .value("Day", series.timestamp!, unit: .day), y: .value("Measurement", WeightFunctions.weightConversions(weightValue: series.value, metric: selectedWeight)) ) } } .chartYScale(domain: lowestValue...highestValue) .chartScrollableAxes(.horizontal) .chartXVisibleDomain(length: xChartVisible) .chartScrollPosition(x: $xScrollPosition) .chartScrollPosition(initialX: xInitialPosition) // .chartXVisibleDomain(length: xChartVisible) .chartXScale(domain: startDate...endDate) I've linked the .chartXVisibleDomain(length: xChartVisible) to a Picker which changes the length to show month, quarter, half year, year: length = 3600 * 24 * 30, length = 3600 * 24 * 90 etc. Each time the xChartVisible changes the chart sometimes stays in the right area if I'm at the end of the x axis, but otherwise moves out of the view. I've noticed the $xScrollPosition number stays exactly the same, even though the visibility has changed but not sure what to do about that. .onAppear { xInitialPosition = weightPeriodFunc.initialScrollDate xScrollPosition = weightPeriodFunc.initialScrollDate.timeIntervalSinceReferenceDate xChartVisible = weightPeriodFunc.length } .onChange(of: weightPeriod) { newValue in xChartVisible = weightPeriodFunc.length xScrollPosition = newPeriodStartDate.timeIntervalSinceReferenceDate } I've set the xScrollPosition as a TimerInterval as I'm also getting the dates from it's location to provide date information above the chart. @State private var xChartVisible : Int = 3600 * 24 * 90 @State private var xScrollPosition : TimeInterval = TimeInterval() @State private var xInitialPosition : Date = Date() @State private var newPeriodStartDate : Date = Date()
