現在、D3階層棒グラフの場合、青色の各バーはそのフォルダ内のすべてのファイルの合計サイズをエンコードしたフォルダを表します。私は、青いバーがの長さ（サイズではない）の総数をエンコードする必要があります。その中のアイテムの例えば、以下の例では、「vis」をクリックすると、その中に7つの項目があります。したがって、「vis」の棒の長さは7でなければなりません。同様に、すべてのフォルダのすべての項目が同じです。 https://bl.ocks.org/mbostock/1283663D3階層型棒グラフ - X軸とY軸の値を変更します

これをコードに追加すると、グラフには何も表示されません。もう一度見てもらえますか？ – ComplexData
あなたは何で構成されていますか？それはどのような特性を持っていますか？あなたが使いたいものは何ですか？使用したいものが「サイズ」と呼ばれている場合は、 'd.value'を' d.size'に置き換えてください。 – MrE
JSONオブジェクトは例のようにまったく同じです。私は、軸の値がすべてのフォルダとサブフォルダのサイズの合計であってはなりません。しかし、それはその中のアイテムの長さでなければなりません。 – ComplexData
