Question

\begin{tikzpicture}[node distance=2.5cm]
\tikzstyle{process} = [rectangle, minimum width=1.5cm, minimum height=0.8cm, text centered, draw=black]
\tikzstyle{resource} = [rectangle, minimum height=0.8cm, text centered]
\tikzstyle{arrow} = [thick,->,>=stealth]
\node (start)[process] {ward};
\node (stage1)[process, right of=start, xshift= 0.5cm]{PHU};

이게 이 사진에 대한 내 코드야 하지만 난 이 사진 같은 사진이 필요해

Answer 1

|-올바른 점을 결정하기 위해 사용할 수 있습니다

노트:

• 변경된 선은 쉽게 찾을 수 있도록 색상을 추가했습니다(앞으로 주의할 점)MWE).
• Schrödinger의 고양이 의견에 따라 \tikzstyle를 \tikzset. 보다TikZ 스타일을 정의하려면 \tikzset 또는 \tikzstyle을 사용해야 합니까? .
• |- 라인 중간에서 연결 |-및 사용에 대한 유용한 참고 자료가 될 수 있습니다 -|.
