如何在乳胶中将文本放在 TikZ 图形下方？

Question

如何在下图中添加文字\begin{tikzpicture}

\usepackage{tikz}
\usepackage[a4paper,margin=0.6in]{geometry}

\tikzset{mystyle/.style={shape=circle,fill=black,scale=0.3}}
\tikzset{withtext/.style={fill=white}}

\begin{document}
\begin{center}
\begin{figure}
\hspace{2cm}
    \begin{minipage}{.5\textwidth}
        \begin{tikzpicture}[scale=1]
            % setup the nodes
            \foreach \x in {0,...,2}
            \foreach \y in {0,...,2}
            {
            \ifnum\x=4
                \ifnum\y=4
                    \node (\x-\y) at (\x,\y){X};
                \else
                    \node[mystyle] (\x-\y) at (\x,\y){};
                \fi
            \else
                \node[mystyle] (\x-\y) at (\x,\y){};
            \fi}
            \draw (0,0) -- (0,1);
             \end{tikzpicture}
       \end{minipage}
\end{figure}
     \end{center}
\end{document}

Answer 1

以下是制作不带环的虚线网格的技巧。使用内置grid命令：

\draw[line width=2pt, line cap=round, dash pattern=on 0pt off 1cm](0,0) grid (2,2);

将line width指定点的直径。

\documentclass{article}

\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
\draw[line width=2pt, line cap=round, dash pattern=on 0pt off 1cm](0,0) grid (2,2);
\draw (0,0)--(0,1);
\node[below=2mm] at (1,0){Here is some text.};
\end{tikzpicture}

\end{document}

Answer 2

像这样？

您的代码稍作修改：

\draw (1,-.5) node [cyan] () {This picture was made with Tikz!};
                \end{tikzpicture}

Answer 3

• 如果您考虑回答上一个问题，那么您应该了解到节点代码可以更简单。
• 您可以在节点底部的第一个节点和最后一个节点之间的路径中添加文本作为节点，即\path (0-0) -- node[below=2mm] {text below nodes} (2-0);

%\documentclass{article}
\documentclass[margin=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}
\tikzset{mystyle/.style={shape=circle,fill=black,scale=0.3}}
\tikzset{withtext/.style={fill=white}}

\begin{document}
%\begin{figure}
%    \begin{minipage}{.5\textwidth}
\begin{tikzpicture}%[scale=.5]
% setup the nodes
\foreach \x in {0,...,2}
\foreach \y in {0,...,2}
{
    \node[mystyle] (\x-\y) at (\x,\y) {};
}
\draw[semithick]    (0-0) -- (0-1);
\path   (0-0) -- node[below=2mm] {text below nodes} (2-0); % <---
\end{tikzpicture}
%       \end{minipage}
%       \end{figure}
\end{document}
