2 个 Tikzpicktures、1 个调整框中的 2 个子图、1 张幻灯片和一些错误

我的 Beamer 演示文稿出现问题，我想在一张幻灯片中插入 2 个 Tikz 子图。为此，我使用了调整框，但出现了错误。

当我单独放置每个 tikzpicture 时没有错误，但是，当我尝试将它们放入 2 个子图时出现错误。

我一直在研究相关问题的答案。问题似乎与图形环境中的子浮点数有关，但我没有满意的答案。

谢谢你！

答案1

离题了，但很重要：

  • 在其他软件包之间，beamer 也加载了graphicx，hyperref因此再次加载它们是多余的
  • beamer 有自己的列表 ( itemize, enumerate) 适用于其特定。因此使用任何其他包关注列表可能会很脆弱

您的问题似乎是由adjustbox（和使用过时的subfigure包）引起的。我建议使用adjustwidth包中的宏changepage。在下面的 MWE 中，我删除了 MWE 中的所有杂乱内容（未使用的代码片段），因此代码现在非常简洁。我还替换了过时的subfigure package with子标题`。
