업데이트된 솔루션(Forest 버전 2+)

MWE는 다음과 같습니다.

\usetikzlibrary{shapes,arrows}
\begin{document}

\tikzset{
  treenode/.style = {align=center, inner sep=2pt, rounded corners = 2pt, minimum width = 2cm, text centered, font=\sffamily},
  block/.style = {treenode, rectangle, white, font=\sffamily\bfseries, draw=black, fill=black},
  phantom/.style = {}
}

\begin{tikzpicture}[->,>=stealth',level/.style={sibling distance = 3in/#1, level distance = 1.5cm}]

서로 다른 노드 사이의 커넥터는 기울어진 선입니다. 이 위치에 가로-세로선을 표시하려면 어떻게 해야 합니까?

답변1

또 다른 옵션은 를 사용하는 것입니다 forest. 이 경우 phantom노드를 생략하고 를 사용하여 등 을 tier정렬 할 수 있습니다. 또한 현재 권장되는 라이브러리 에서 제공하는 화살표의 현재 구문을 사용하도록 코드를 업데이트했습니다 . 트리를 지정하는 데 훨씬 적은 타이핑 작업이 필요하기 때문에 마음에 듭니다 !P7P4P5arrows.metaforest

이 코드를 사용하면 상자의 너비( \widthBox)와 높이( ), 상자 사이의 가로( ) 및 세로( ) 거리를 선택하기만 하면 됩니다 . 그러면 도면이 그에 따라 자동으로 조정됩니다.\heightBox\horiDist\vertDist
