调整图片宽度

Question

我正在尝试插入三幅水平排列的图片，横跨整个页面。目前，它们彼此叠放，而不是彼此相邻。

\begin{figure}[H]  
   \centering  
   \includegraphics{"Plot 2".png}  
  \includegraphics{"Plot 3".png}  
  \includegraphics{"Plot 4".png}  
  \caption{Data Set 1 - split by country}  
  \label{fig:Data Set 1 - split by country}  
\end{figure}

Answer 1

或者简单来说：

\documentclass{article}
\usepackage{graphicx} % to use example images
%---------------------------------------------------------------%
\usepackage{showframe}% fro whow page layout
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

\begin{document}
\begin{figure}[ht]
    \centering
\includegraphics[width=0.3\linewidth]{example-image}\hfil
\includegraphics[width=0.3\linewidth]{example-image}\hfil
\includegraphics[width=0.3\linewidth]{example-image}
\caption{Data Set 1 - split by country}
\label{fig:Data Set 1 - split by country}
\end{figure}
\begin{figure}[ht]
\includegraphics[width=0.3\linewidth]{example-image}\hfill
\includegraphics[width=0.3\linewidth]{example-image}\hfill
\includegraphics[width=0.3\linewidth]{example-image}
\caption{Data Set 1 - split by country}
\label{fig:Data Set 1 - split by country}
\end{figure}
\end{document}

Answer 2

您可以使用水平填充来实现这一点，但是您需要给图像一个相对宽度，请查看这个：

\documentclass{article}
\usepackage{graphicx} % to use example images
\usepackage{showframe} % to show magins

\begin{document}
\begin{figure}
\includegraphics[width=0.3\linewidth]{example-image}\hspace*{\fill}%
\includegraphics[width=0.3\linewidth]{example-image}\hspace*{\fill}%
\includegraphics[width=0.3\linewidth]{example-image}
\caption{Data Set 1 - split by country}
\label{fig:Data Set 1 - split by country}
\end{figure}
\end{document}

如果您不想让图像组碰到边距（或者想要以较小的尺寸显示它们），也可以将图像组居中。只需在开头和结尾添加更多水平填充：

% Same preamble as above
\begin{document}
\begin{figure}
\hspace*{\fill}\includegraphics[width=0.3\linewidth]{example-image}
\hspace*{\fill}\includegraphics[width=0.3\linewidth]{example-image}
\hspace*{\fill}\includegraphics[width=0.3\linewidth]{example-image}\hspace*{\fill}%
\caption{Data Set 1 - split by country}
\label{fig:Data Set 1 - split by country}
\end{figure}
\end{document}
