JavaFXチャート - Java.lang.IllegalArgumentException：重複シリーズが追加されました

Question

私はclear()チャートからデータを削除する方法を使用しています。

この機能で

@FXML 
public void restartButtonClicked() { 
    System.out.println("Restarting..."); 
    timeLine.getKeyFrames().clear(); 

    axesTest.getData().clear(); 
} 

が、ボタンがクリック得れば - それは動作します..しかし、二度目、私はつもりだしながら、それをクリックして、それが例外をスロー：

だから、問題はとして138ラインであります同様の方法からのコードの159行で：

@SuppressWarnings("unchecked") 
@FXML 
public void startButtonClicked(ActionEvent event) { 
if (comboBox.getValue() == null) { 
    System.out.print("Nie wybrano opcji."); 
} else { 
    if(comboBox.getValue().equals("Gaussian Wave : non-Dispersive")) { 
     System.out.println("Gaussian Wave : non-Dispersive"); 
     axesTest.setTitle("Gaussian Wave : non-Dispersive"); 

     series.setName("bla"); 
     series1.setName("ssad"); 
     series2.setName("asf"); 

     seriesList.add(series); 
     seriesList.add(series1); 
     seriesList.add(series2); 

     timeLine = new Timeline(); 
     gaussianWave = new GaussianWave(seriesList, axes, timeLine); 
     seriesList = gaussianWave.draw(); 
     gaussianWave.update(axesTest); 

     axesTest.getData().retainAll(); 
     axesTest.getData().addAll(seriesList); 
    } else if(comboBox.getValue().equals("Gaussian Wave : Dispersive")) { 
     System.out.println("Gaussian Wave : Dispersive"); 
     axesTest.setTitle("Gaussian Wave : Dispersive"); 

     series.setName("bla"); 
     series1.setName("ssad"); 
     series2.setName("asf"); 

     seriesList.add(series); 
     seriesList.add(series1); 
     seriesList.add(series2); 

     timeLine = new Timeline(); 
     gaussianWaveDispersive = new GaussianWaveDispersive(seriesList, axes, timeLine); 
     seriesList = gaussianWaveDispersive.draw(); 
     gaussianWaveDispersive.update(axesTest); 

     axesTest.getData().retainAll(); 
     axesTest.getData().addAll(seriesList); 
    } 
} 

}

と問題がである：

axesTest.getData().addAll(seriesList); 

グラフからすべてのデータを消去した後にこの例外が発生するのはなぜですか？どうすればこの問題を解決できますか？

Answer 1

あなたはSeriesのdataPropertyに保存されているObservableListをクリアする：（？）

axesTest.getData().clear(); 

いますが、中間のリストを使用するには、直接Dataを追加するのではなく、seriesList呼ば：

seriesList.add(series); 
seriesList.add(series1); 
seriesList.add(series2) 

... 

axesTest.getData().addAll(seriesList); 

問題要素を追加する前にseriesListをクリアしていないので、2回目のクリックで要素が2回表示されるため、結果はとなります0。

gaussianWave = new GaussianWave(seriesList, axes, timeLine); 
seriesList = gaussianWave.draw(); 

を seriesListこれらの行の後に、以前の Dataオブジェクトが含まれているようです：

実は私はここで何が起こるか分かりません。
