구부러진 가장자리를 더욱 세밀하게 제어

Question

내 코드는 다음과 같습니다.

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows, automata}

\begin{document}

\begin{tikzpicture}[
        > = stealth, % arrow head style
        shorten > = 1pt, % don't touch arrow head to node
        auto,
        node distance = 3cm, % distance between nodes
        semithick % line style
    ]

    \tikzstyle{every state}=[
    draw = black,
    thick,
    fill = white,
    minimum size = 4mm
    ]
    
    \node[state] (a) at (0,4) {A};
    \node[state] (b) at (4,4) {B};
    \node[state] (c) at (2,2) {C};
    \node[state] (d) at (0,0) {D};
    \node[state] (e) at (4,0) {E};
    
    \path[->] (a) edge node {$e_1$} (b);
    \path[->] (b) edge node {$e_2$} (e);
    \path[->] (a) edge node {$e_3$} (c);
    \path[->] (c) edge node {$e_4$} (e);
    \path[->] (d) edge node {$e_5$} (e);
    \path[->] (a) edge node {$e_6$} (d);
    \path[->, style={bend left = 145}] (b) edge node {$e_7$} (d);
\end{tikzpicture}

\end{document}

이것이 생성하는 결과입니다:

다음 그림과 같이 가장자리 e_7이 노드 E를 중심으로 구부러지도록 노력 중입니다.

e_7이 구부러지는 방식을 어떻게 제어할 수 있나요?

Answer 1

의 남동쪽 약간에 제어점이 있는 베지어 곡선을 사용할 수 있습니다 E.

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows, automata,calc}

\begin{document}

\begin{tikzpicture}[
        > = stealth, % arrow head style
        shorten > = 1pt, % don't touch arrow head to node
        auto,
        node distance = 3cm, % distance between nodes
        semithick % line style
    ]

    \tikzstyle{every state}=[
    draw = black,
    thick,
    fill = white,
    minimum size = 4mm
    ]

    \node[state] (a) at (0,4) {A};
    \node[state] (b) at (4,4) {B};
    \node[state] (c) at (2,2) {C};
    \node[state] (d) at (0,0) {D};
    \node[state] (e) at (4,0) {E};

    \path[->] (a) edge node {$e_1$} (b);
    \path[->] (b) edge node {$e_2$} (e);
    \path[->] (a) edge node {$e_3$} (c);
    \path[->] (c) edge node {$e_4$} (e);
    \path[->] (d) edge node {$e_5$} (e);
    \path[->] (a) edge node {$e_6$} (d);
    %                                V--V - change here to adjust
    \path[->,draw] (b) .. controls ($(e)+(2,-1)$) .. node {$e_7$} (d);
\end{tikzpicture}

\end{document}

Phelpe Oleinik의 답변에 대한 대안:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows, automata,calc}

\begin{document}

\begin{tikzpicture}[
        > = stealth, % arrow head style
        shorten > = 1pt, % don't touch arrow head to node
        auto,
        node distance = 3cm, % distance between nodes
        semithick % line style
    ]

    \tikzstyle{every state}=[
    draw = black,
    thick,
    fill = white,
    minimum size = 4mm
    ]

    \node[state] (a) at (0,4) {A};
    \node[state] (b) at (4,4) {B};
    \node[state] (c) at (2,2) {C};
    \node[state] (d) at (0,0) {D};
    \node[state] (e) at (4,0) {E};

    \path[->] (a) edge node {$e_1$} (b);
    \path[->] (b) edge node {$e_2$} (e);
    \path[->] (a) edge node {$e_3$} (c);
    \path[->] (c) edge node {$e_4$} (e);
    \path[->] (d) edge node {$e_5$} (e);
    \path[->] (a) edge node {$e_6$} (d);
    \draw[->] (b) to[in= 45,out=-45]  ($(e)+(0.5,-0.5)$)node[right]{$e_7$} to[in= -45,out=-135] (d);
\end{tikzpicture}

looseness여기서 사용할 수 있는 옵션 도 있습니다 :

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows, automata}

\begin{document}

\begin{tikzpicture}[
        > = stealth, % arrow head style
        shorten > = 1pt, % don't touch arrow head to node
        auto,
        node distance = 3cm, % distance between nodes
        semithick % line style
    ]

    \tikzstyle{every state}=[
    draw = black,
    thick,
    fill = white,
    minimum size = 4mm
    ]

    \node[state] (a) at (0,4) {A};
    \node[state] (b) at (4,4) {B};
    \node[state] (c) at (2,2) {C};
    \node[state] (d) at (0,0) {D};
    \node[state] (e) at (4,0) {E};

    \path[->] (a) edge node {$e_1$} (b);
    \path[->] (b) edge node {$e_2$} (e);
    \path[->] (a) edge node {$e_3$} (c);
    \path[->] (c) edge node {$e_4$} (e);
    \path[->] (d) edge node {$e_5$} (e);
    \path[->] (a) edge node {$e_6$} (d);
    \path[->, style={bend left = 70, looseness = 2}] (b) edge node {$e_7$} (d);
\end{tikzpicture}
