将标题与图像对齐

Question

我有以下代码：

\documentclass{article}
\usepackage{float}
\usepackage{siunitx}
\usepackage{graphicx}

    \begin{document}
        By plotting the attenuation in $ \si{\decibel s} $ we get the following graphs:
        \begin{itemize}
            \item \underline{For Butterworth:}
            \vspace{-0.1cm}
            \begin{figure}[H]
                \centering
                \includegraphics[width=0.9\textwidth]{sample_photo.png}
                \caption{Tabulated LPP normalized attenuation curve for Butterworth.}
            \end{figure}
            There are $ n $ number of zeros, in our case $ n=3 $ zeros of each kind. As we can see, the transmission zeros are in the infinity...
        \end{itemize}
    \end{document}

输出结果如下：

如您所见，与整体文本相比，标题和图像似乎是左对齐的。 有没有办法将图形和标题都移到右侧？ 添加\hspace图像有效，但添加标题无效。

谢谢。

由于您的图像不必浮动，因此您可以measuredfigure通过threeparttable嵌套在简单 center环境中的环境获得正确的居中：

    \documentclass{article}
    \usepackage[utf8]{inputenc}
    \usepackage[showframe]{geometry}
    \usepackage{caption}%loat,
    \usepackage{threeparttable, floatrow}
    \usepackage[demo]{graphicx}
    \usepackage{siunitx}

    \begin{document}

    By plotting the attenuation in $ \si{\decibel s} $ we get the following graphs:
    \begin{itemize}
        \item \underline{For Butterworth:}
        \vspace{-0.1cm}
        \begin{center}
            \begin{measuredfigure}%
                        \includegraphics[width=0.9\linewidth]{sample_photo.png}
                        \captionof{figure}{Tabulated LPP normalized attenuation curve for Butterworth.}
            \end{measuredfigure}
        \end{center}
        There are $ n $ number of zeros, in our case $ n=3 $ zeros of each kind. As we can see, the transmission zeros are in the infinity...
    \end{itemize}

    \end{document}

你只需要图片无浮动，使图像的宽度相对于包的\linewidth使用。\captionofcapt-of

显示边距边缘并且没有段落缩进可能示例更清晰（注意：图像是故意压平的，只需按比例移除高度即可）：

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{capt-of,lipsum,parskip}
\usepackage{graphicx}
\begin{document}
\lipsum[2]
\begin{itemize}
\item \lipsum[3]
\item For Butterworth:\par
\includegraphics[width=\linewidth,height=1cm]{example-image-a}
\captionof{figure}{Tabulated LPP normalized attenuation curve for Butterworth.} 
\lipsum[4]                
\item \lipsum[5]
\end{itemize}
\lipsum[6]
\end{document}

如果想要将较小的图像居中，则在\hfil图像上方放置一个，或者用 {\centering ... \par}或括起来就足够了\begin{center}...\end{center}。
