私は、データ駆動型のこの D3 チャートを使用しています。それは機能していますが、2 番目のツールチップを追加すると、両方が表示されなくなり、コンソールでエラーが発生します。
私が取り組んでいるオリジナルはここにあります: http://bl.ocks.org/Caged/6476579
これは、mouseover イベントで呼び出された関数がデータにアクセスできないことを意味すると思います。
svg7-2.html:105 Uncaught TypeError: Cannot read property 'frequency2'
of undefined

そして、ここに私の完全なコードがあります:

テキストが修正された以前の回答とは異なり、datumツールチップにを渡す必要があります。
.on("mouseover", function(d) {
tip.show(d);
tip2.show(d);
}).on("mouseout", function(d) {
tip.hide();
tip2.hide();
});
