如果图形名称不在子部分中，如何从中删除 0？

tag-icon • tag-icon floats chngcntr
如果图形名称不在子部分中，如何从中删除 0？

我使用 chngcntr 包来相应地命名我的图形。

\counterwithin{figure}{section}
\counterwithin{figure}{subsection}
\counterwithin{figure}{subsubsection}
\counterwithin{figure}{paragraph}

我的问题是，当一个图仅出现在小节中而不出现在小节和段落中时，图名看起来是这样的：图 1.1.0.0.1。但我希望它看起来像这样：图 1.1.1 如果有人能帮忙，我将不胜感激 :)

你可以做到。但要三思（或者，最好多思几次）是否要做这件事。

\documentclass{article}
\usepackage{capt-of} % just for the example

\setcounter{secnumdepth}{4}
\counterwithin*{figure}{section}
\counterwithin*{figure}{subsection}
\counterwithin*{figure}{subsubsection}
\counterwithin*{figure}{paragraph}
\newcommand{\notifzero}[1]{%
  \ifnum\value{#1}>0
    \arabic{#1}.%
  \fi
}
\renewcommand{\thefigure}{%
  \notifzero{section}%
  \notifzero{subsection}%
  \notifzero{subsubsection}%
  \notifzero{paragraph}%
  \arabic{figure}%
}

\begin{document}

\captionof{figure}{A}

\section{B}

\captionof{figure}{C}

\subsection{D}

\captionof{figure}{E}

\subsubsection{F}

\captionof{figure}{G}

\paragraph{H} Some text

\captionof{figure}{I}

\section{J}

\captionof{figure}{K}

\end{document}

我以前\captionof只是为了制作一张较短的图（否则几个图就需要更多的页面）。

这是一个使用该ifthen包及其\ifthenelse宏的解决方案。它适用于figure以及表号。

在此处输入图片描述

\documentclass{article}
\usepackage[T1]{fontenc}
\counterwithin{figure}{paragraph}
\counterwithin{table}{paragraph}
\setcounter{secnumdepth}{4}

\usepackage{ifthen,etoolbox}
\newcommand\figandtabnums{%
\ifthenelse{\value{subsection}=0}{%
   \renewcommand\thefigure{\thesection.\arabic{figure}}%
   \renewcommand\thetable{\thesection.\arabic{table}}}{%
   \ifthenelse{\value{subsubsection}=0}{%
      \renewcommand\thefigure{\thesubsection.\arabic{figure}}%
      \renewcommand\thetable{\thesubsection.\arabic{table}}}{%
      \ifthenelse{\value{paragraph}=0}{%
         \renewcommand\thefigure{\thesubsubsection.\arabic{figure}}%
         \renewcommand\thetable{\thesubsubsection.\arabic{table}}}{%
            \renewcommand\thefigure{\theparagraph.\arabic{figure}}%
            \renewcommand\thetable{\theparagraph.\arabic{table}}}}}}
\pretocmd{\caption}{\figandtabnums}{}{} 
  
\begin{document}
\section{Buenos días}
\begin{figure}[h!]\caption{First figure}\label{fig:uuu} \end{figure}
\begin{table}[h!]\caption{First table}\label{tab:uuu} \end{table}

\subsection{Bonjour}
\begin{figure}[h!]\caption{Second figure}\label{fig:vvv} \end{figure}
\begin{table}[h!]\caption{Second table}\label{tab:vvv} \end{table}

\subsubsection{Buon giorno}
\begin{figure}[h!]\caption{Third figure}\label{fig:www} \end{figure}
\begin{table}[h!]\caption{Third table}\label{tab:www} \end{table}

\paragraph{Kaliméra} What a day!

\begin{table}[h!]\caption{Fourth table}\label{tab:xxx} \end{table}
