こんにちはでdivの内側にツールチップを表示します。私はD3を初めて使っています。何か愚かなことを聞​​いたら私を許してください。私は、各行の横に表示するのではなく、四角形のdivの中にホバリングして積み重ねたエリアチャートのツールチップを表示しようとしています。今まで私は理解してこれを達成しましたが、矩形のdivをツールチップに追加して、その中のデータをホバー上に表示することはできません。私を助けてください。事前のおかげです。

+0

レイチェル、あなたはホバー値に境界線を表示しようとしています? –

+0

あなたの質問は明確ではありません...ツールチップが来ている、あなたが達成したいもののスクリーンショットかもしれません.. – Cyril

+0

ご迷惑をおかけして申し訳ありません。実際には、今のところ起こっている領域の境界に印刷するのではなく、特定の長方形のボックス内の線にホバーに表示されるすべての値を表示したいと考えています。条件には、各値に個別のボックスを作成するのではなく、スタック領域チャートのすべての値を表示する単一の長方形のボックスが必要です。 – Rach
