ノードのマトリックス上に複数のノードを収集する

Question

最終ノードのサイズ/配置に問題があります。

実際、私は不器用にノードを印刷し、フィットノードを使用して複数の子をカバーしています。

それは美しくありません。もっと賢く、もっと自然なものがあるはずです。

Answer 1

既存のノードから既存のノードの北端（北端の中心ではない）に垂直線を描く構文は次のとおりです。

\draw (node1) -- (node1.south|-node2.north)

したがって、マトリックスの最後の行を削除し、「投資家」ノードを必要な場所に配置します。私はそれらを1.2cmマトリックスの最後の行の下に配置します。最初のノードはノードの下にあり、2 番目のノードはとm-4-2の中点の下にあります。m-4-4m-4-5

次にコマンド

\draw[myline] (m-4-1.south) -- (m-4-1.south|-new1.north);

(m-4-1.south)は、 の北端までまっすぐ下から描画します(new1)。これが、最初の「Investor」ノードに付けた名前です。
