如何在乳胶主体中包含一个图形

Question

我有一个这样的图，它有 2 个子图；如何将其包含在我的其他主文档中？我可以使用 \input{figure_name}，该图会显示在我的父文档中。

\documentclass{article}

\usepackage{subcaption}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{adjustbox}

\begin{document}


\begin{figure}
        \centering
        \begin{subfigure}[b]{0.4\textwidth}
            \begin{tikzpicture}
                \begin{axis}[
                    trig format=rad,    % <---
                    domain=0:1,         % <---
                    samples=501,        % <---
                    no marks]           % <---
                \addplot {sin(10*x};
                
                \legend{$\sin(10x)$}
                \end{axis}
                    \end{tikzpicture}
        \end{subfigure}
        \hfill
        \begin{subfigure}[b]{0.4\textwidth}
            \begin{tikzpicture}
                \begin{axis}[
                    trig format=rad,    % <---
                    domain=0:1,         % <---
                    samples=501,        % <---
                    no marks]           % <---
                \addplot {sin(100*x};
               
                \legend{$\sin(100x)$}
                \end{axis}
            \end{tikzpicture}
        \end{subfigure}
        \caption{Increasing oscillatory function}
\end{figure}
    
\end{document}

像这样：

我假设两个图像具有相同的axis设置，因此可以在本地写入\pgfplotsset，从而使图形代码更短一些：

\documentclass{article}

\usepackage{subcaption}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
    \begin{figure}
    \centering
\pgfplotsset{% common settings for both images
    width=\linewidth,
    scale only axis,
    trig format=rad,    % <---
    domain=0:pi/2,      % <---
    samples=501,        % <---
    no marks,           % <---
% added,˛
    every axis plot post/.append style={semithick},
    legend style={font=\footnotesize,
                  cells={anchor=west}}
            }

\begin{subfigure}[b]{0.45\textwidth}
    \begin{tikzpicture}
\begin{axis}
\addplot {sin(10*x};
\addplot {sin(25*x)};
\addplot {sin(50*x)};

\legend{$\sin(10x)$,$\sin(25x)$,$\sin(50x)$}
\end{axis}
    \end{tikzpicture}
\end{subfigure}
\hfil
\begin{subfigure}[b]{0.45\textwidth}
    \begin{tikzpicture}
\begin{axis}
\addplot {sin(100*x)};
\addplot {sin(150*x))};
\addplot {sin(200*x))};

\legend{$\sin(100x)$,$\sin(150x)$,$\sin(200x)$}
\end{axis}
    \end{tikzpicture}
\end{subfigure}
\caption{Increasing oscillatory function}
\label{fig:??}
    \end{figure}
\end{document}

如您所见，如果您有平行的图像，它们在给定的页面布局中会非常窄，因此不太清晰。要提高图表的可见性，您有几种选择：

• 更改页面布局并放大\textwidth
• 将一张图片放在另一张图片之上
• 缩小第二幅图像的域

附录：

• 我想知道为什么你的子图没有标题
• 如果不需要，您可以考虑groupplot使用subfigures
• 在下面的 MWE 中，被视为：
  • 第二幅图像的简化波域
  • \textwidth通过使用geometry包增加
  • 子图标题中的数量使用 ˙siunnitx` 包Č
