节点形状问题（菱形）

我正在绘制流程图。菱形节点显示不正确。我的最小工作示例如下。ShareLaTeX 没有问题，但它在我的计算机上不起作用。

\usepackage{tikz}

\usetikzlibrary{shapes.geometric, arrows, fit}

\tikzstyle{decision} = [diamond, minimum width=2cm, minimum height=1cm, text centered, text width=2cm, draw=black, inner sep=1pt, fill=green!10]
\tikzstyle{startstop} = [rectangle, rounded corners, minimum width=3cm, minimum height=1cm,text centered, draw=black, fill=red!30]
\tikzstyle{io} = [trapezium, trapezium left angle=70, trapezium right angle=110, minimum width=2cm, minimum height=1cm, text centered, draw=black, fill=blue!30]
\tikzstyle{process} = [rectangle, minimum width=3cm, minimum height=1cm, text centered,text width=5cm, draw=black, fill=orange!30]
\tikzstyle{endloop} = [ellipse, minimum width=2cm, minimum height=1cm, text centered, text width=3cm, draw=black, inner sep=1pt]
\tikzstyle{input} = [coordinate]
\tikzstyle{output} = [coordinate]
\tikzstyle{arrow} = [thick,->,>=stealth]

\begin{document}

    \begin{tikzpicture} [node distance=2cm]

        \node [input, name=input] {};
        \node(dec1)[decision, below of=input]{$Round <= Limit$};

    \end{tikzpicture}

\end{document}

  • 我无法重现你的问题，完成你的 mwe 后，它工作正常
  • 您使用一个旧的定义（带有过时的tizstyle语法）来定义流程图的节点样式。我建议更新它，就像下面 mwe 中所使用的一样（从我的这里)：

\documentclass[border=3mm,
                tikz]{standalone}
\usetikzlibrary{arrows.meta,
                calc, chains,
                quotes,
                positioning,
                shapes.geometric}

\begin{document}
%---------------------------------------------------------------%
\begin{tikzpicture}[
    node distance = 8mm and 16mm,
      start chain = A going below,
      base/.style = {draw, minimum width=32mm, minimum height=8mm,
                     align=center, on chain=A},
 startstop/.style = {base, rectangle, rounded corners, fill=red!30},
   process/.style = {base, rectangle, fill=orange!30},
        io/.style = {base, trapezium,
                     trapezium left angle=70, trapezium right angle=110,
                     fill=blue!30},
  decision/.style = {base, diamond, fill=green!30},
  every edge quotes/.style = {auto=right}]
                    ]
\node (dec1) [decision] {$Round <= Limit$};
    \end{tikzpicture}
\end{document}

在此处输入图片描述

  • 如果您希望在序言中使用流程图的节点样式（对于更多流程图，您可以按照以下方式执行此操作：

    \documentclass[border=3mm,
                tikz]{standalone}
\usetikzlibrary{arrows.meta,
                calc, chains,
                quotes,
                positioning,
                shapes.geometric}

\tikzset{FlowChart/.style={     % <---
      start chain = A going below,
      base/.style = {draw, minimum width=32mm, minimum height=8mm,
                     align=center, on chain=A},
 startstop/.style = {base, rectangle, rounded corners, fill=red!30},
   process/.style = {base, rectangle, fill=orange!30},
        io/.style = {base, trapezium,
                     trapezium left angle=70, trapezium right angle=110,
                     fill=blue!30},
  decision/.style = {base, diamond, fill=green!30},
  every edge quotes/.style = {auto=right}
                        }% end of FlowChart styles
  }


\begin{document}
%---------------------------------------------------------------%
\begin{tikzpicture}[FlowChart,  % <---
    node distance = 8mm and 16mm,
                    ]
\node(dec1)[decision]{$Round <= Limit$};
    \end{tikzpicture}
\end{document}

  • 笔记：我认为将节点声明为坐标（用于输入和输出）没有任何好处。为此，\coordinate如果您真的需要，您可以简单地使用。

  • 您可以找到一个相对简单的流程图代码示例这里。

  • 上述文档示例也适用于任何其他文档类别，不仅限于standalone。例如：

    \documentclass[ pdftex, oneside,    
                Einseitiger Druck. 12pt,    
                Schriftgroesse parskip=half,    
                topmargin = 10pt,   headheight = 33pt,  headsepline,    footsepline,    
                footheight = 16pt,  abstracton, DIV=calc,   
                Satzspiegel berechnen BCOR=8mm, headinclude=false, footinclude=false, listof=totoc, toc=bibliography,   
                ]{scrreprt}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,
                calc, chains,
                quotes,
                positioning,
                shapes.geometric}

\tikzset{FlowChart/.style={     % <---
      start chain = A going below,
      base/.style = {draw, minimum width=32mm, minimum height=8mm,
                     align=center, on chain=A},
 startstop/.style = {base, rectangle, rounded corners, fill=red!30},
   process/.style = {base, rectangle, fill=orange!30},
        io/.style = {base, trapezium,
                     trapezium left angle=70, trapezium right angle=110,
                     fill=blue!30},
  decision/.style = {base, diamond, fill=green!30},
  every edge quotes/.style = {auto=right}
                        }% end of FlowChart styles
  }

\begin{document}
%---------------------------------------------------------------%
\begin{tikzpicture}[FlowChart,  % <---
    node distance = 8mm and 16mm,
                    ]
\node(dec1)[decision]{$Round <= Limit$};
    \end{tikzpicture}
\end{document}

给出的结果与之前的 mwe 相同。
