如何在乳膠主體中包含圖形

Question

我有一個像這樣的數字，它有兩個子數字；如何將其包含在我的其他主文檔中？我可以在哪裡使用 \input{figure_name} 並且該圖顯示在我的父文檔中。

\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}

Answer 1

像這樣：

我假設兩個圖像具有相同的axis設置，因此可以在本地寫入\pgfplotsset，這樣可以使圖形代碼更短一些：

\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}

正如您所看到的，如果您有並行的圖像，它們在給定的頁面佈局中會相當窄，因此不太清晰。為了提高圖表的可見性，您有多種選擇：

• 透過放大更改頁面佈局\textwidth
• 將一張圖片放在另一張圖片上方
• 縮小第二張影像的域

附錄：

• 我想知道為什麼你的子圖沒有標題
• 如果不需要它們，您可以考慮使用groupplot使用subfigures
• 在下面的 MWE 中，考慮：
  • 第二張影像的縮減波域
  • \textwidth透過使用增加geometry包
  • 對於子圖標題中的數量，使用 ˙siunnitx` 包Č
