新手 - 如何將 3 個圖像放到一張幻燈片上，其中 2 個在上面，一個在下面

Question

我有這個小例子，

\documentclass{beamer}

\mode<presentation>
{
  \usetheme{Boadilla}     
  \usecolortheme{wolverine}
  \usefonttheme{structurebold}  
  \setbeamertemplate{navigation symbols}{}
  \setbeamertemplate{caption}[numbered]
\setbeamertemplate{itemize items}[ball]
} 

\usepackage{array,amsmath,booktabs}
\usepackage{amsmath}
\usepackage[version=4]{mhchem}
\usepackage{mathtools}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}

\begin{frame}
\begin{figure}[H]
  \centering
  \begin{subfigure}[b]{0.28\linewidth}
    \includegraphics[clip, trim=1 1.75 3 1, width=50mm,scale=0.35]{Image1}
     \caption{Substrate-Enzyme association}
  \end{subfigure}
  \begin{subfigure}[b]{0.28\linewidth}
    \includegraphics[clip, trim=1 1.75 3 1, width=50mm,scale=0.35]{Image2}
    \caption{Complex dissociation}
  \end{subfigure} \\
  \begin{subfigure}[b]{0.3\linewidth}
    \includegraphics[clip, trim=1 1.75 3 1, width=50mm,scale=0.35]{Image3}
    \caption{Product formation}
  \end{subfigure}
  \caption{Prior and posterior after 100, 200 and 300 reactions for reaction in Micahelis-Menten model}
  \label{fig:boat2}
\end{figure}
\begin{itemize}
\item as more reactions take place, posterior becomes narrower 
\end{itemize}
\end{frame}

 \end{document}

我試圖讓這些圖像對齊，以便我在頂行有 2 個圖像，然後是第三個圖像和下一行，並在 2 個頂部圖像之間居中。

但我嘗試的所有格式化都變得越來越糟。

您可以使用列：

\documentclass{beamer}

\mode<presentation>
{
  \usetheme{Boadilla}     
  \usecolortheme{wolverine}
  \usefonttheme{structurebold}  
  \setbeamertemplate{navigation symbols}{}
  \setbeamertemplate{caption}[numbered]
\setbeamertemplate{itemize items}[ball]
} 

\usepackage{array,amsmath,booktabs}
\usepackage{amsmath}
\usepackage[version=4]{mhchem}
\usepackage{mathtools}
\usepackage{graphicx}
\usepackage{subcaption}

\begin{document}

\begin{frame}\centering
  \begin{columns}
    \begin{column}{0.5\textwidth}
  \begin{figure}
    \includegraphics[clip, trim=1 1.75 3 1, width=30mm,scale=0.3]{Image1}
     \caption*{Substrate-Enzyme association}
  \end{figure}
    \end{column}
    \begin{column}{0.5\textwidth}
  \begin{figure}[b]
    \includegraphics[clip, trim=1 1.75 3 1, width=30mm,scale=0.3]{Image2}
    \caption*{Complex dissociation}
  \end{figure} 
    \end{column}
  \end{columns}
\vspace{-10px}  
  \begin{columns}
    \begin{column}{0.5\textwidth}
    \begin{figure}[b]
      \includegraphics[clip, trim=1 1.75 3 1, width=30mm,scale=0.3]{Image3}
      \caption*{Product formation}
  \end{figure}
    \end{column}
  \end{columns}
\vspace{-20px}  
\begin{columns}
  \begin{column}{\textwidth}
\begin{figure}[H]
  \caption{\centering{}Prior and posterior after 100, 200 and 300 reactions for reaction in Micahelis-Menten model}
  \label{fig:boat2}
\end{figure}
\vspace{-25px}
\begin{itemize}
\item as more reactions take place, posterior becomes narrower 
\end{itemize}
  \end{column}
\end{columns}
\end{frame}

 \end{document}

Answer 2

一些評論和觀察：

• 在beamer文件中，figure環境table不會浮動。
• 事實上，在文件中，使用和環境beamer沒有什麼意義——我想，除了作為和環境的容器之外。哦，只需將標題材料放在 的參數中即可。figuretablesubfiguresubtable\frametitle
• 如果你真的想擬合所有三個圖和在單幀環境itemize中，您幾乎肯定需要並排放置所有三個圖表，而不是 2 個圖表放在第一行，第三個圖表放在第二行。
• 在您提供的程式碼中，\includegraphics指令的寬度和比例選項相互衝突。僅使用選項，但不能同時使用兩者。

\documentclass[demo]{beamer} % omit 'demo' option in real document

\setbeamertemplate{itemize items}[ball] } 
\usepackage{array,mathtools,booktabs}
