我正在试验一个实时的情节，但它不是实时显示。1秒后，即睡眠10次所需的时间，它只是完整地显示绘图。
为了 onCreate ```
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

/* Buttons */
graph = (GraphView) findViewById(R.id.graph);

}

当我点击按钮

public void runRealTime(View v){

graph.removeAllSeries();

/**------ Set x bounds ------ */
Viewport vp = graph.getViewport();
vp.setXAxisBoundsManual(true);
vp.setMinX(-5);
vp.setMaxX(20);

/**------ Init ------ */
LineGraphSeries<DataPoint> series;
series = new LineGraphSeries<>();
series.setColor(Color.BLACK);
graph.addSeries(series);

/**------ Real Time plot ------ */
for (int i = 0; i < 10; i++) {
    series.appendData(new DataPoint(i, i), true, 40);

    try {
        Thread.sleep(100);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

}
