隐藏标题中的图号，引用时显示图号

Question

我在文本中引用图表时遇到了一个奇怪的问题。编译后的 PDF 中的红色方框显示，图表的链接已建立。但红色方框中显示的是问号而不是图表编号。有人能帮我解决这个问题吗？

PDF 快照在这里：

代码如下（我使用 \usepackage{caption} 来抑制标题中的图形编号，我交换了 \caption 和 \label 的顺序，但没有帮助）：

\begin{description}
    \item[ideal market theorem:] the ideal market picture consists of an uptrend, top, downtrend, and bottom (figure~\ref{fig:DowIdealMarketPicture}), interspersed with retracements and consolidations, the purpose of the ideal market picture is to provide a generalized model of the stock market's price behavior over time, it presumes that prices \underline{oscillate} over long periods based on the accumulated \underline{emotion} of investors as well as the facts of the \underline{business cycle}
        \begin{figure}[hbt]
            \centering
            \includegraphics[scale=0.54]{Figure/DowIdealMarketPicture}
            \caption*{figure 2.1 the Dow theory ideal market picture}
            \label{fig:DowIdealMarketPicture}
        \end{figure}
\end{description}

日志文件包含以下警告消息：

包标题警告：\label 在输入行 150 上没有正确的引用。请参阅标题包文档以获取解释。

Answer 1

您必须\@currentlabel手动设置。如果您使用hyperref同样，另外\phantomsection还应提供正确的超目标。

\documentclass{article}

\usepackage{caption,graphicx}
\usepackage{hyperref}

\makeatletter
\newcommand{\setrefnumber}{\phantomsection\renewcommand{\@currentlabel}}%
\makeatother

\begin{document}

\begin{description}
    \item[ideal market theorem:] the ideal market picture consists of an uptrend, 
    top, downtrend, and bottom (figure~\ref{fig:DowIdealMarketPicture}), interspersed 
    with retracements and consolidations, the purpose of the ideal market picture is 
    to provide a generalized model of the stock market's price behavior over time, it 
    presumes that prices \underline{oscillate} over long periods based on the 
    accumulated \underline{emotion} of investors as well as the facts of the

    \begin{figure}[hbt]
      \setrefnumber{2.1}%
      \centering
      \includegraphics[width = .5\linewidth]{example-image}
      \caption*{figure 2.1 the Dow theory ideal market picture}
      \label{fig:DowIdealMarketPicture}
    \end{figure}

请注意如何\setrefnumber{<whatever>}放置在环境的顶部figure，以便\reference 超链接跳转到图的顶部。
