Swiftui在使用路径绘制折线图时对每条线进行动画处理

import SwiftUI

struct LineChartView: View {
    @State private var data = [CGPoint(x: 50, y: 100), CGPoint(x: 150, y: 200), CGPoint(x: 250, y: 150)]
    @State private var isAnimating = false

    var body: some View {
        ZStack {
            ForEach(data.indices, id: \.self) { index in
                Path { path in
                    path.move(to: data[index])
                    if index < data.count - 1 {
                        path.addLine(to: data[index + 1])
                    }
                }
                .stroke(Color.blue, lineWidth: 2)
                .animation(Animation.easeInOut(duration: 1).delay(Double(index) * 0.2), value: isAnimating)
            }
        }
        .onAppear {
            self.isAnimating = true
        }
    }
}

struct ContentView: View {
    var body: some View {
        LineChartView()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
