Javafx上带有每个系列复选框的面积图

我有一个面积图，带有一些复选框，可以选择要在面积图上显示的系列。问题是我有以下错误：

Exception in thread "JavaFX Application Thread" java.lang.IllegalArgumentException: Duplicate series added

这是当3个复选框之一更改其值时执行的代码

   /**AreaChart<Integer,Double> multipleGraphic;
        * CheckBox HeartRateCheck,PedalingRateCheck,AverageSpeedCheck;
        * XYChart.Series AvSpeed = new XYChart.Series();
        * XYChart.Series Cadence = new XYChart.Series();
        * XYChart.Series HeartRate = new XYChart.Series();
        **/


    private void setMultiGraph() {

            multipleGraphic.getData().removeAll(multipleGraphic.getData());
            multipleGraphic.getData().clear();

            if (HeartRateCheck.isSelected() && PedalingRateCheck.isSelected() && AverageSpeedCheck.isSelected()) {
                multipleGraphic.getData().addAll(AvSpeed, Cadence, HeartRate);
            }

            if (!HeartRateCheck.isSelected() && PedalingRateCheck.isSelected() && AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(AvSpeed, Cadence);
            }
            if (HeartRateCheck.isSelected() && !PedalingRateCheck.isSelected() && AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(AvSpeed, HeartRate);
            }
            if (HeartRateCheck.isSelected() && PedalingRateCheck.isSelected() && !AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(Cadence, HeartRate);
            }

            if (!HeartRateCheck.isSelected() && !PedalingRateCheck.isSelected() && AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(AvSpeed);
            }
            if (!HeartRateCheck.isSelected() && PedalingRateCheck.isSelected() && !AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(Cadence);
            }
            if (HeartRateCheck.isSelected() && !PedalingRateCheck.isSelected() && !AverageSpeedCheck.isSelected()) {

                multipleGraphic.getData().addAll(HeartRate);
            }
        }

谢谢。

根据需要，使用复选框选定的属性更改侦听器从图表中添加或删除序列

private void addSeriesListener(BooleanProperty selected, final XYChart.Series series) {
    selected.addListener((observable, wasSelected, isSelected) -> {
        if (isSelected) {
            chart.getData().add(series);
        } else {
            chart.getData().remove(series);
        }
    });
}
. . .
addSeriesListener(heartRateCheck.selectedProperty(), heartRateSeries);
addSeriesListener(cadenceCheck.selectedProperty(), cadenceSeries);
addSeriesListener(speedCheck.selectedProperty(), speedSeries);

完整示例应用程序

快速添加/删除系列时，此解决方案失败。我想有一些背景工作正在进行，所以添加/删除操作系统系列是异步的。。。？关于如何解决这个问题有什么想法吗？JavaFX是一个同步框架，所以像您描述的任何问题都将是一个奇怪的错误，并且会因为不同的原因出现。您可以尝试关闭图表的动画，看看是否适合您。如果你认为这是一个平台错误，你也可以在bugreport.java.com上提交错误；将解决此问题。我已尝试关闭动画，但问题仍然存在抱歉，我无法复制您在关闭jdk8u60动画时遇到的问题。
