HighChartsを使用してグラフを作成しましたが、その幅がバーの高さを超える（データバーにデータラベルを入れることはできません）。特定のポイントのdataLabelの 'enabled：false'プロパティを設定しましたが、そのエフェクトがグラフに反映されていません。 
highChartsで幅がバーの高さを超えている場合、dataLabelを無効にする

</html>私はjQueryのを使用して問題を解決してきたが、それは素晴らしいものだプロパティを設定することで簡単に行うことができます。また、プロパティが設定されている場合、エフェクトが反映されないのはなぜですか？
ありがとうございました。
。しかし、dataLabelがbarで調整されていない場合、上のコードのようにenabledプロパティをfalseにしていますが、効果は見られません。 –
うーん..ハイチャートの古いバージョンがあるかもしれない？ご覧のとおり、私のデモはうまくいきます。あなたがjsFiddleで問題を再現できるなら、私はそこで何が起こるかを見ることができます。 –
