连接图表 tikz + pgfplots

我有两张图形想要合并为一张，但我更想把它们放在文本中，如下所示：

\documentclass[12pt]{article}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{lipsum}

\begin{document}
\lipsum[66]
\begin{figure}[h]
\centering
...
\end{figure}
\lipsum[66]
\end{document}

我的图表代码如下：

\documentclass[border=1mm]{standalone}
\usepackage{tikz}
\usepackage[spanish,es-noshorthands]{babel}
\begin{document}

\begin{tikzpicture}
\draw[-stealth] (-1,0) -- (2.5,0) node[below]{$u$};;
\draw[-stealth] (0,-1) -- (0,2.5) node[left]{$v$};
\draw[blue] (-0.8,2)--(2.3,2);
\draw[blue] (-0.8,0.5)--(2.3,0.5);
\draw[red] (2,-0.8)--(2,2.3);
\draw[red] (0.5,-0.8)--(0.5,2.3);

\node at (0,2) [blue, font=\footnotesize, below left]{$1$};
\node at (0,0.5) [blue, font=\footnotesize, below left]{$1$};
\node at (2,0) [red, font=\footnotesize, below left]{$1$};
\node at (0.5,0) [red, font=\footnotesize, below left]{$1$};

\end{tikzpicture}
\end{document}

不确定我是否理解正确了你的问题...如果你想要将两个图放在一起，只需将它们放在一起即可。你可以使用baseline垂直对齐选项，或者你可以查看这里。

我将您的圆环图（计算量很大）保存在一个名为的文件中torus.pdf。然后您只需将两个图形放在同一行上：

\documentclass[12pt]{article}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16,width=10cm}
\usepackage{lipsum}
\usepackage[spanish,es-noshorthands]{babel}
\begin{document}
\lipsum[66]
\begin{figure}[h]
    \centering
    \begin{tikzpicture}[baseline=-1cm]
        \draw[-stealth] (-1,0) -- (2.5,0) node[below]{$u$};;
        \draw[-stealth] (0,-1) -- (0,2.5) node[left]{$v$};
        \draw[blue] (-0.8,2)--(2.3,2);
        \draw[blue] (-0.8,0.5)--(2.3,0.5);
        \draw[red] (2,-0.8)--(2,2.3);
        \draw[red] (0.5,-0.8)--(0.5,2.3);

        \node at (0,2) [blue, font=\footnotesize, below left]{$1$};
        \node at (0,0.5) [blue, font=\footnotesize, below left]{$1$};
        \node at (2,0) [red, font=\footnotesize, below left]{$1$};
        \node at (0.5,0) [red, font=\footnotesize, below left]{$1$};

        % Add the arrow!
        \draw[thick, ->] (3, 1.5) to[bend left] ++(2,0);

    \end{tikzpicture}
    \includegraphics[scale=0.6]{torus.pdf}
\end{figure}
\lipsum[66]
\end{document}

在此处输入图片描述

但请注意，如果您希望图表始终处于该位置，则不应该使用figure---该环境是为了漂浮的人物。在这种情况下，只需使用center环境，否则，如果没有空间容纳图形，它就会移动。
