GraphView Android：圖形的奇怪行為

Question

我的graphview第一次嘗試代碼有問題：

GraphView graphView;
GraphViewSeries series;

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

    GraphViewData[] data = new GraphViewData[4];
    Double[] x_values = new Double[] { 1.0, 2.0, 3.0, 4.0 };
    Double[] y_values = new Double[] { 1.0, 2.0, 3.0, 4.0 };

    for (int i = 0; i < data.length; i++) {
        data[i] = new GraphViewData(x_values[i], y_values[i]);
    }

    series = new GraphViewSeries(data);

    graphView = new LineGraphView(this, "Title");
    graphView.addSeries(series);
    graphView.setScrollable(true);
    graphView.setScalable(true);
    graphView.setBackgroundColor(Color.BLACK);

    LinearLayout l = (LinearLayout) findViewById(R.id.linearLay);
    l.addView(graphView);
}

兩個問題：-背景仍然是白色-放大后，我無法縮小-x軸上的標簽未顯示

Answer 1

關於白色背景，請嘗試添加：

((LineGraphView) graphView).setDrawBackground(true);

您可以這樣設置標簽顏色：

graphView.getGraphViewStyle().setHorizontalLabelsColor(Color.BLACK);
graphView.getGraphViewStyle().setVerticalLabelsColor(Color.BLACK);

我希望它能起作用！
