(I'm using macOS 14.5 and Xcode 15.4) I have a Swift Chart on macOS that needs to scroll horizontally. Simplified version: Chart(dataPoints) { data in LineMark(x: .value("X Axis", data.x), y: .value("Y Axis", data.y)) } .chartScrollableAxes(.horizontal) .chartXVisibleDomain(length: 10) The above code works fine, except that it does not show scroll bars. On a Mac with no trackpad, this means there's no mechanism to scroll the chart. On my MacBook Pro with a trackpad, I can scroll the chart with a 2-finger swipe gesture, but there are no transient scroll bars to show the relative size of the visible part of the chart. How do I add visible scroll bars to the chart so that I can scroll on Macs with no trackpad?

I'm running macOS 26.3 and using Xcode 26.4. I'm trying to create a SwiftUI Chart that can scroll horizontally. In the SwiftUI Preview, and also running the app on macOS, the chart displays a scrollbar, but the scrollbar does not respond to mouse interaction (dragging the scrollbar, or clicking in the gutters on either side of the scrollbar). Here's the sample code: import SwiftUI import Charts private struct DataPoint: Identifiable { let id: Int let x: Double let value: Double } struct ContentView: View { private let points: [DataPoint] = (0..<60).map { index in let wave = sin(Double(index) * 0.28) * 18 let trend = Double(index) * 0.35 return DataPoint(id: index, x: Double(index), value: 60 + wave + trend) } var body: some View { Chart(points) { point in BarMark( x: .value("Data Point", point.x), y: .value("Value", point.value) ) .foregroundStyle(.blue.gradient) } .chartScrollableAxes(.horizontal) // Doesn't work: // .scrollIndicators(.hidden) // .never also does not work .chartXVisibleDomain(length: 20) .padding() } } #Preview { ContentView() }
