xAxis.setLowerBound（1）导致javaFX中条形图中的条消失

Question

我希望xAxis值从1到10.当我将xAxis lowerBound设置为'1'而不是'0'时，图表中的条形图正在消失。

NumberAxis xAxis = new NumberAxis();
xAxis.setAutoRanging(false);
xAxis.setLowerBound(1);
xAxis.setUpperBound(10);
xAxis.setTickUnit(1);

final CategoryAxis yAxis = new CategoryAxis();
final BarChart<Number,String> bc =new BarChart<Number,String>(xAxis,yAxis);

XYChart.Series series1 = new XYChart.Series();
series1.getData().add(new XYChart.Data(5, "XYZ"));

如何解决此问题？

我刚试过这个，它对我有用。我正在使用java 8。

public class HorizBarChart extends Application {
@Override public void start(Stage stage) {
    final NumberAxis xAxis = new NumberAxis();
    xAxis.setAutoRanging(false);
    xAxis.setLowerBound(1);
    xAxis.setUpperBound(10);
    xAxis.setTickUnit(1);
    final CategoryAxis yAxis = new CategoryAxis();
    final BarChart<Number,String> bc = new BarChart<>(xAxis,yAxis);

    XYChart.Series series1 = new XYChart.Series();
    series1.setName("1");       
    series1.getData().add(new XYChart.Data(5, "XYZ"));
    series1.getData().add(new XYChart.Data(1, "ABC"));
    series1.getData().add(new XYChart.Data(10, "def"));
    Scene scene  = new Scene(bc,800,600);
    bc.getData().addAll(series1);
    stage.setScene(scene);
    stage.show();
}
}
