在android中绘制从高度X掉落的球的高度v / s时间图

Question

我正在尝试构建一个显示所有高度和时间之间的图形并显示反弹总数的应用程序，其中用户可以输入高度，系数也可以更改。

到目前为止我所做的-------- >>>>>>

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");
}

我想根据下图绘制图表任何帮助，将不胜感激，谢谢。

您使用的公式是错误的，并且将androidchart库用于线性图的displayig
