Swift Charts — 3D Visualization
Basic 3D Surface Plot
import SwiftUI
import Charts
struct Surface3DView: View {
var body: some View {
Chart3D {
SurfacePlot(x: "X", y: "Y", z: "Z") { x, y in
sin(x) * cos(y)
}
}
}
}
Custom Viewing Angle
@State private var pose: Chart3DPose = .default
Chart3D {
SurfacePlot(x: "X", y: "Y", z: "Z") { x, y in sin(x) * cos(y) }
}
.chart3DPose(pose)
// Predefined poses: .default, .front, .back, .top, .bottom, .left, .right
// Custom pose:
Chart3DPose(azimuth: .degrees(45), inclination: .degrees(30))
Interactive Rotation
struct InteractiveChart: View {
@State private var pose: Chart3DPose = .default
var body: some View {
Chart3D {
SurfacePlot(x: "X", y: "Y", z: "Z") { x, y in sin(x) * cos(y) }
}
.chart3DPose($pose) // Bind for user interaction (drag to rotate)
}
}
Surface Styling
Chart3D {
SurfacePlot(x: "X", y: "Y", z: "Height") { x, y in
sin(x) * cos(y)
}
.foregroundStyle(
.linearGradient(
colors: [.blue, .green, .yellow, .red],
startPoint: .bottom, endPoint: .top
)
)
}
.chart3DSurfaceStyle(.wireframe) // Wireframe only
.chart3DSurfaceStyle(.solid) // Solid surface
.chart3DSurfaceStyle(.solidWithEdges) // Solid + wireframe overlay
Axis Customization
Chart3D {
SurfacePlot(x: "Longitude", y: "Latitude", z: "Elevation") { x, y in
elevation(at: x, y)
}
}
.chartXAxisLabel("Longitude")
.chartYAxisLabel("Latitude")
.chartZAxisLabel("Elevation (m)")
.chartXScale(domain: -180...180)
.chartYScale(domain: -90...90)
From Data Points
struct DataPoint3D: Identifiable {
var x: Double, y: Double, z: Double
var id = UUID()
}
Chart3D(dataPoints) { point in
// Mark3D or other 3D mark types
}
visionOS Volumetric Window
// visionOS only — renders chart as volumetric object
WindowGroup {
Chart3D { SurfacePlot(x: "X", y: "Y", z: "Z") { x, y in sin(x) * cos(y) } }
}
.windowStyle(.volumetric)
.defaultSize(width: 0.5, height: 0.5, depth: 0.5, in: .meters)
