避免在图表列表中显示 chapter.section 的数量

Question

使用时，是否可以不显示图形列表中图形前面的数字\listoffigures？

例如，仅显示图 a、图 b、图 c，而不是 1.1 图 a、2.1 图 b，...

代码示例：

\documentclass[a4paper,12pt]{book}
\usepackage[demo]{graphicx}
\usepackage{blindtext}

\begin{document}

\author{TeXstudio Team}
\title{Simple Book Example}
\date{January 2013}

\frontmatter
\maketitle
\tableofcontents
\listoffigures

\mainmatter
\chapter{AAA}
\blindtext
\begin{figure}[hpb]
    \centering
    \includegraphics[width=3cm]{example-image-a}
    \caption{figure a}
\end{figure}

\chapter{BBB}
\blindtext
\begin{figure}[hpb]
    \centering
    \includegraphics[width=3cm]{example-image-b}
    \caption{figure b}
\end{figure}

\chapter{CCC}
\blindtext
\begin{figure}[hpb]
    \centering
    \includegraphics[width=3cm]{example-image-c}
    \caption{figure c}
\end{figure}

\end{document}

Answer 1

以下是使用包（版本 3.20 或更新版本）的建议tocbasic：

\documentclass[a4paper,12pt]{book}
\usepackage[demo]{graphicx}
\usepackage{blindtext}

\usepackage{tocbasic}[2016/05/10]% needs version 3.20 or newer
\DeclareTOCStyleEntry[
  entrynumberformat=\gobble,
  numwidth=0pt,
  indent=0pt
]{tocline}{figure}
\newcommand\gobble[1]{}
