javaFX的StackedBarGraph值介于0.0和1.0之间仅使用最近添加的系列

Question

javaFX的StackedBarGraph值介于0.0和1.0之间，仅使用最近添加的系列。由于某种原因，它忘记了之前添加的系列。我该如何解决？

应该是这样（注意相对比例而不是实际值）：

但实际上看起来像是：

Oracle网站（https://docs.oracle.com/javafx/2/charts/bar-chart.htm）的示例代码已修改为使用介于0.0和1.0之间的值：

package main;

import java.util.Arrays;

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.scene.Scene;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedBarChart;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;

public class Test extends Application {

    final static String austria = "Austria";
    final static String brazil = "Brazil";
    final static String france = "France";
    final static String italy = "Italy";
    final static String usa = "USA";
    final CategoryAxis xAxis = new CategoryAxis();
    final NumberAxis yAxis = new NumberAxis();
    final StackedBarChart<String, Number> sbc = new StackedBarChart<String, Number>(
            xAxis, yAxis);
    final XYChart.Series<String, Number> series1 = new XYChart.Series<String, Number>();
    final XYChart.Series<String, Number> series2 = new XYChart.Series<String, Number>();
    final XYChart.Series<String, Number> series3 = new XYChart.Series<String, Number>();

    @Override
    public void start(Stage stage) {
        stage.setTitle("Bar Chart Sample");
        sbc.setTitle("Country Summary");
        xAxis.setLabel("Country");
        xAxis.setCategories(FXCollections.<String> observableArrayList(Arrays.asList(austria, brazil, france, italy, usa)));
        yAxis.setLabel("Value");
        series1.setName("2003");
        series1.getData().add(new XYChart.Data<String, Number>(austria, 0.02560134));
        series1.getData().add(new XYChart.Data<String, Number>(brazil,  0.02014882));
        series1.getData().add(new XYChart.Data<String, Number>(france,  0.01000000));
        series1.getData().add(new XYChart.Data<String, Number>(italy,   0.03540715));
        series1.getData().add(new XYChart.Data<String, Number>(usa,     0.01200000));
        series2.setName("2004");
        series2.getData().add(new XYChart.Data<String, Number>(austria, 0.05740185));
        series2.getData().add(new XYChart.Data<String, Number>(brazil,  0.04194119));
        series2.getData().add(new XYChart.Data<String, Number>(france,  0.04526337));
        series2.getData().add(new XYChart.Data<String, Number>(italy,   0.11732016));
        series2.getData().add(new XYChart.Data<String, Number>(usa,     0.01484527));
        series3.setName("2005");
        series3.getData().add(new XYChart.Data<String, Number>(austria, 0.4500065));
        series3.getData().add(new XYChart.Data<String, Number>(brazil,  0.4483576));
        series3.getData().add(new XYChart.Data<String, Number>(france,  0.1872218));
        series3.getData().add(new XYChart.Data<String, Number>(italy,   0.1755731));
        series3.getData().add(new XYChart.Data<String, Number>(usa,     0.9263368));
        Scene scene = new Scene(sbc, 800, 600);
        sbc.getData().addAll(series1, series2, series3);
        stage.setScene(scene);
        stage.show();
    }

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

看起来此问题与：JavaFx StackedBar Chart Issue

有关

该文章的修复也适用于此问题。不幸的是，该修复涉及导入Oracle的一个私有软件包，这会限制解决方案的可移植性。

在那篇文章中，问题是负值。在我的帖子中，值介于0.0和1.0之间。
