Android 绘制折线图

用了一段时间的 Jetpack Compose ，感觉写 UI 的效率确实会提升不少 。

配合 AI 编程绘制了一个折线图。供大家学习参考！

@Composable
fun TemperatureChart() {
    val timeLabels = listOf("7:00", "8:00", "9:00", "10:00", "11:00", "12:00", "13:00", "14:00")
    val temperaturePoints = listOf(
        Pair(0f, 36.8f),
        Pair(0.2f, 37.2f),
        Pair(0.4f, 36.9f),
        Pair(0.6f, 36.5f),
        Pair(0.8f, 37.0f),
        Pair(1f, 35.7f)
    )
    
    var selectedPoint by remember { mutableStateOf<Pair<Float, Float>?>(null) }
    var selectedX by remember { mutableStateOf<Float?>(null) }
