图形对齐

Question

我已经编译了这段代码，但右边的部分有点乱。我想让右边的两个图表一个在另一个下面对齐（居中），但我无法做到这一点。有什么办法可以解决这个问题吗？我知道 minipage 的代码可能有问题，也许有更有效的方法。“caminotoro.pdf”是这。我知道放置链接不是最合适的，但在这种情况下，我不希望在将其转换为 png 或类似格式时尺寸发生变化。

Answer 1

\centering我建议在第二个小页面的开始处使用对齐命令。

    \begin{minipage}{0.5\textwidth}
        \centering
    \includegraphics[scale=0.8]{caminotoro.pdf} \\ 
    {
    \flattorus[3]{5}{7}
    %\includegraphics[scale=0.8]{caminotoro.pdf}
    } \end{minipage}
    \end{tabular}

这将产生以下输出：

Answer 2

不喜欢表格和小页面。它们只会占用图片太多空间。这是让你的图片更紧凑的简单方法。
