使用 alltt 进行 Beamer 和缩进

Question

以下投影机代码

\begin{frame}[fragile]
\frametitle{PROC TEMPLATE for a fancy graph (part 2)}
\begin{alltt}
      rowaxes;
        rowaxis /label = 'Infant Mortality (\%)'
         griddisplay = on;
        rowaxis /label = '' griddisplay = on;
      endrowaxes;
    layout overlay; 
      scatterplot x = unemployment 
        y = infantmortality;
      loessplot x = unemployment
        y = infantmortality/nomarkers;
      loessplot x = unemployment
           y = infantmortality/smooth = 1;
      ellipse  x = unemployment y = infantmortality
             /type = predicted;
     endlayout;
\end{alltt}
\end{frame}

缩进如图所示，直到以“椭圆”开头的行，该行设置为左对齐。在“失业”后添加段落标记没有帮助。

有任何想法吗？

我看不到任何问题，当我创建一个完全的semiverbatim文档来自您的代码片段！但是，beamer 知道也可以使用的环境：

\documentclass{beamer}
\begin{document}

\begin{frame}[fragile]
\frametitle{PROC TEMPLATE for a fancy graph (part 2)}
\begin{semiverbatim}
      rowaxes;
        rowaxis /label = 'Infant Mortality (\%)'
         griddisplay = on;
        rowaxis /label = '' griddisplay = on;
      endrowaxes;
    layout overlay; 
      scatterplot x = unemployment 
        y = infantmortality;
      loessplot x = unemployment
        y = infantmortality/nomarkers;
      loessplot x = unemployment
           y = infantmortality/smooth = 1;
      ellipse  x = unemployment y = infantmortality
             /type = predicted;
     endlayout;
\end{semiverbatim}
\end{frame}

\end{document}
