tikzpicture 的标题错位

\subfloat在使用 tikzpicture 时，我无法放置子字幕。

这是我的 MWE：

它可以编译，但是我设置的子标题\subfloat[...]却放错了位置：

mwe 的输出

我现在完全迷失了，因为在 beamer 类中使用完全相同的代码可以完全正常工作。

我想避免使用软件包subfigure或subcaption。我读到过将子浮点数包装在迷你页面中可能是一个好主意，但它不起作用。

对此有什么想法吗？

编辑 我找到了一个对我有用的解决方案，使用了@Troy 和@John_Kormylo 的提示，我注释掉了它\setcapwidth{0.9\textwidth}并将其添加到每个图形和表格中，除了我使用 tikzpicture 的图形和表格中……将其放入\setcapwidth{\textwidth}有问题的子浮点数中并没有改变任何东西。

KOMA 类实际上与 不兼容subfig。您可以改用subcaption。

从 KOMA-Script 版本 3.20 开始，您可以改用\setcapdynwidth。\setcapwidth摘自 KOMA-Script 文档：

请注意，\setcapwidth将width立即设置为参数宽度的值，就像\setlength会做的那样。如果您想要width在设置标题时使用的值，则可以使用。如果您使用长度或其他命令作为参数\setcapdynwidth，结果可能会有所不同。\linewidthwidth
