java在安卓中为从X高度落下的球绘制高度v/s时间图

Question

我正在尝试构建一个应用程序，它显示所有高度和时间之间的图形，并显示反弹的总数，用户可以在其中输入高度，也可以更改系数

我到目前为止所做的----->&燃气轮机&燃气轮机&燃气轮机&燃气轮机&燃气轮机

LineGraphSeries<DataPoint> series;
double start_height = 20.0;
double x, y = 0.0;
double time = 0.0;
double velocity = 0.0;

double gravity = 10.0;
double step = 0.1;
//v=u+at
double h = 0.0;
double reachesGround = 0.0;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    GraphView graphView = findViewById(R.id.graphView);
    series = new LineGraphSeries<>();


    velocity = Math.sqrt(2*gravity*start_height);
    reachesGround = velocity/gravity;

    for (double i = start_height; i > 0.0; i--){
        //Time
        x += 0.1;
        //calculate next height to which the ball bounces
        y = i - ((10/100)*i);

        series.appendData(new DataPoint(x, y), true, (int) reachesGround);
    }

    graphView.addSeries(series);
    graphView.setTitle("Height v/s time graph");
}

我想在下图的基础上绘制图表
任何帮助都将不胜感激，谢谢

您使用的公式是错误的，使用androidchart库来显示线性图表
