JavaFX lineChart问题

Question

我有以下代码：

 final TreeMap<Integer, Double> ADLMap = new TreeMap<>();

    public static void main(String[] args) {
    launch(args);
}

  @Override
public void start(Stage stage) {
    final String currency = "currreny";
    ADL(currency);
    stage.setTitle("Line Chart Sample");
    //defining the axes
    final NumberAxis xAxis = new NumberAxis();
    final NumberAxis yAxis = new NumberAxis();
    xAxis.setLabel("Number of Month");
    //creating the chart
    final LineChart<Number, Number> lineChart = new LineChart<Number, Number>(xAxis, yAxis);
    lineChart.setTitle("Stock Monitoring, 2010");
    //defining a series
    XYChart.Series ADLChart = new XYChart.Series();
    XYChart.Series regularChart = new XYChart.Series();

    ADLChart.setName("My portfolio");

    chartMap.entrySet().forEach(entry -> regularChart.getData().add(new XYChart.Data(entry.getKey(), entry.getValue())));

    //populating the series with data
    ADLMap.entrySet().forEach(entry -> ADLChart.getData().add(new XYChart.Data(entry.getKey(), entry.getValue())));
    System.out.println(ADLMap);
    lineChart.setCreateSymbols(false);

    Scene scene = new Scene(lineChart, 1200, 1000);
    //lineChart.getData().add(regularChart);
    lineChart.getData().add(ADLChart);

    stage.setScene(scene);
    stage.show();


    final double SCALE_DELTA = 1.1;
    lineChart.setOnScroll(new EventHandler<ScrollEvent>() {
        public void handle(ScrollEvent event) {
            event.consume();

            if (event.getDeltaY() == 0) {
                return;
            }

            double scaleFactor = (event.getDeltaY() > 0) ? SCALE_DELTA : 1 / SCALE_DELTA;

            lineChart.setScaleX(lineChart.getScaleX() * scaleFactor);
            lineChart.setScaleY(lineChart.getScaleY() * scaleFactor);
        }
    });

    lineChart.setOnMousePressed(new EventHandler<MouseEvent>() {
        public void handle(MouseEvent event) {
            if (event.getClickCount() == 2) {
                lineChart.setScaleX(1.0);
                lineChart.setScaleY(1.0);
            }
        }
    });

}

   private void ADL(final String currency) {
    double counter = -4000000.0;
    int mapCounter = 0;
    while (counter < 4000000) {
        ADLMap.put(mapCounter++, counter++);
    }
}

该地图包含以下值:键n+1 n欧元，取值范围从-10.000.000到+ 10.000.000。

My Problem: --它根本不绘制值。至少我什么也看不见。

有人能帮忙吗？

我的错误是，一个复杂的算法产生了一个inifnity，它被放置在TreeMap中。图形无法绘制ofc。
