tikz 환경에 더하기 기호 추가

Question

흐름도를 만드는 중입니다.

현재 나는 다음을 가지고 있습니다:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric,arrows,amsmath}

\tikzstyle{process}=[rectangle,minimum width=3cm,minimum height=1cm, text centered, draw=black, fill=orange!30]
\tikzstyle{decision}=[diamond,minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=green!30]

\tikzstyle{arrow}=[thick,->,>=stealth]

    \begin{document}

    \begin{tikzpicture}[node distance=2cm]
        \node (start) [process] {
        $\text{A}_{it}$
        };

        \node (in1) [process, below of=start] {$\text{B}_{it}$};
        \node (in2) [process, below of=in1] {$\text{C}_{it}$};
        \node (pro2) [decision, right of=in1, xshift=2cm] {$\text{ D}_{it}$};
        \draw [arrow] (start)--(pro2);
        \draw [arrow] (in1)--(pro2);
        \draw [arrow] (in2)--(pro2);
    \end{tikzpicture}
    \end{document}

이는 세 개의 노드 A, B, C를 D에 연결합니다.

이제 D 오른쪽에 또 다른 노드 E를 만들고 싶지만 화살표 대신 더하기 기호를 추가하고 싶습니다.

이를 수행할 수 있는 방법이 있습니까?

Answer 1

이와 같이 ?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz,amsmath}
\usetikzlibrary{shapes.geometric,arrows.meta,positioning}

\tikzstyle{process}=[rectangle,minimum width=3cm,minimum height=1cm, text centered, draw=black, fill=orange!30]
\tikzstyle{decision}=[diamond,minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=green!30]

\tikzstyle{arrow}=[thick,->,>=stealth]

    \begin{document}

    \begin{tikzpicture}[node distance=2cm]
        \node (start) [process] {
        $\text{A}_{it}$
        };

        \node (in1) [process, below of=start] {$\text{B}_{it}$};
        \node (in2) [process, below of=in1] {$\text{C}_{it}$};
        \node (pro2) [decision, right= 2cm of in1] {$\text{ D}_{it}$};
        \node (pro3) [decision, right= 2cm of pro2] {$\text{ E}_{it}$};
        \draw [arrow] (start)--(pro2);
        \draw [arrow] (in1)--(pro2);
        \draw [arrow] (in2)--(pro2);
        \draw (pro2) edge node[draw,fill=white,circle]{+} (pro3);
    \end{tikzpicture}
    \end{document}

부록

\tikzstyletikz 버전 2.10부터 더 이상 사용되지 않으므로 \tikzset which give를 사용해야 합니다.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz,amsmath}
\usetikzlibrary{shapes.geometric,arrows.meta,positioning}

%\tikzstyle{process}=[rectangle,minimum width=3cm,minimum height=1cm, text centered, draw=black, fill=orange!30]
%\tikzstyle{decision}=[diamond,minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=green!30]
%
%\tikzstyle{arrow}=[thick,->,>=stealth]

\tikzset{
    process/.style={rectangle,minimum width=3cm,minimum height=1cm, text centered, draw=black, fill=orange!30},
    decision/.style={diamond,minimum width=3cm, minimum height=1cm, text centered, draw=black, fill=green!30},
        }
    \begin{document}

    \begin{tikzpicture}[node distance=2cm,arrows={-stealth},thick]
        \node (start) [process] { $\text{A}_{it}$ };

        \node (in1) [process, below of=start] {$\text{B}_{it}$};
        \node (in2) [process, below of=in1] {$\text{C}_{it}$};
        \node (pro2) [decision, right= 2cm of in1] {$\text{ D}_{it}$};
        \node (pro3) [decision, right= 2cm of pro2] {$\text{ E}_{it}$};
        \draw [->] (start)--(pro2);
        \draw [->] (in1)--(pro2);
        \draw [->] (in2)--(pro2);
        \draw (pro2) edge node[fill=white]{+} (pro3);
    \end{tikzpicture}
    \end{document}
