图片标题仅部分居中

Question

我有两个彼此相邻的图形，我想将图形标题居中，但要完全居中，即包括图 xx： 居中。

这是我正在使用的代码：

\begin{figure}[!tbph]
    \centering
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[scale=0.2]{images/pie_chart_mobile.png}
        \caption{Frequency of playing mobile video games}
        \label{fig:pie_chart_mobile}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[scale=0.2]{images/pie_chart_multiplayer.png}
        \caption{Preference regarding multiplayer games}
        \label{fig:pie_chart_multiplayer}
    \end{minipage}
\end{figure}

这就是我得到的：

我真正想要的是这个：

我试过包装justification=centering上的caption，没用。有什么想法吗？

编辑：MWE：

\RequirePackage[l2tabu,orthodox]{nag}

\documentclass[headsepline,footsepline,footinclude=false,oneside,fontsize=11pt,paper=a4,listof=totoc,bibliography=totoc]{scrbook} % one-sided

\PassOptionsToPackage{table,svgnames,dvipsnames}{xcolor}

\usepackage[%
  backend=biber,
  url=false,
  style=alphabetic,
  maxnames=4,
  minnames=3,
  maxbibnames=99,
  firstinits,
  uniquename=init]{biblatex} % TODO: adapt bibliography style
\usepackage[demo]{graphicx}
\usepackage{caption}

\captionsetup{justification=centering}

\begin{document}

\begin{figure}[!tbph]
    \centering
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[scale=0.2]{images/pie_chart_mobile.png}
        \caption{Frequency of playing mobile video games}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[scale=0.2]{images/pie_chart_multiplayer.png}
        \caption{Preference regarding multiplayer games}
    \end{minipage}
\end{figure}

\end{document}

结果：

Answer 1

您必须在 KOMA-Script 中将标题缩进设置为，0pt并将格式设置为\centering如下所示：

\setcapindent{0pt}
\addtokomafont{caption}{\centering}

因此，以下操作应该有效：

\RequirePackage[l2tabu,orthodox]{nag}

\documentclass[headsepline,footsepline,footinclude=false,oneside,fontsize=11pt,paper=a4,listof=totoc,bibliography=totoc]{scrbook} % one-sided

\PassOptionsToPackage{table,svgnames,dvipsnames}{xcolor}

\usepackage[%
  backend=biber,
  url=false,
  style=alphabetic,
  maxnames=4,
  minnames=3,
  maxbibnames=99,
  firstinits,
  uniquename=init]{biblatex} % TODO: adapt bibliography style
\usepackage[demo]{graphicx}
\usepackage{caption}

% The fix:
\setcapindent{0pt}
\addtokomafont{caption}{\centering}

\begin{document}
\begin{figure}
    \centering
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_mobile.png}
        \caption{Frequency of playing mobile video games}
        \label{fig:pie_chart_mobile}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_multiplayer.png}
        \caption{Preference regarding multiplayer games}
        \label{fig:pie_chart_multiplayer}
    \end{minipage}
\end{figure}
\end{document}

Answer 2

包裹caption

caption带有选项的包justification=centering通常有助于：

\documentclass{article}
\usepackage[demo]{graphicx}% demo only because of missing images
\usepackage{caption}
\captionsetup{justification=centering}

\begin{document}
\begin{figure}[!tbph]
    \centering
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_mobile.png}
        \caption{Frequency of playing mobile video games}
        \label{fig:pie_chart_mobile}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_multiplayer.png}
        \caption{Preference regarding multiplayer games}
        \label{fig:pie_chart_multiplayer}
    \end{minipage}
\end{figure}
\end{document}

班级memoir

课程memoir提供\captionstyle：

\documentclass{memoir}
\usepackage[demo]{graphicx}% demo only because of missing images
\captionstyle{\centering}

\begin{document}
\begin{figure}[!tbph]
    \centering
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_mobile.png}
        \caption{Frequency of playing mobile video games}
        \label{fig:pie_chart_mobile}
    \end{minipage}
    \hfill
    \begin{minipage}[b]{0.4\textwidth}
        \includegraphics[width=\linewidth]{images/pie_chart_multiplayer.png}
        \caption{Preference regarding multiplayer games}
        \label{fig:pie_chart_multiplayer}
    \end{minipage}
\end{figure}
