子图使用 sidenotes 包中的 sidecaptions 来中断图编号

Question

我正在将标题放在包的边缘sidenotes。我还经常使用subfigure来自的环境subcaptions来注释子图并引用它们。

我现在注意到这种组合破坏了编号。MWE：

我得到了正确编号的图 1.1 和 1.2，它们都没有使用环境subfigure。图 1.3 的编号正确，但参考子图将计数器增加到 1.4a 和 1.4b，而不是 1.3a。此外，下一个图的编号为 1.5，完全跳过了 1.4。

显然，子图似乎打开了一个新的图，或者至少增加了图计数器。观察到的行为与是否引用子图无关。下一个图的编号总是错误的。

有人知道到底发生了什么吗？最重要的是，如何解决它？

为了直接解决一些潜在的问题并让您了解替代方法应提供哪些功能，这里列出了我这样做的一些原因：我将标题放在边缘，因为那里 (i) 有空间，并且 (ii) 我还在那里设置了整个子图集的图例，这比把它放在其中一个图中方便得多，并且我在格式方面比放在图下方的标题中有更多的自由。我使用该subcaption包是因为它效果最好，并且语法比 KOMA-sidecaption 更简单、更简短。特别是标题可能比图形本身的高度更长，然后标题文本会放在正文旁边。KOMA 方法不允许这样做（或者我没有让它工作）。

如果有人采用不同的方法实现上述功能，我也会非常欢迎。

Answer 1

\sidecaption{...}增加标题编号，因此subfigure“看到”的标题增加计数器的值caption而不是使用的值\sidecaption。这意味着必须\sidecaption{...}在subfigure环境之后。通过此更改，您的 MWE 给出了预期结果：

编辑： 在此更改中，您需要考虑，它\sidecaption{...}在包中定义sidenotes，但遗憾的是没有选择其相对于浮动内容的位置的选项。它仅允许手动移动标题位置。如上图所示，可以利用此功能\sidecaption[][-6em]{...}：

Answer 2

正如 Zarko 所解释的那样，subfigure环境会增加figure计数器。一个丑陋的黑客建议是每次调用子图时手动减少计数器，方法是\addtocounter{figure}{-1}在代码中添加。这必须完成之内调用第一个用于图形编号和引用的工作figure之前的环境。subfigure

这样，您sidecaption仍将与图形顶部对齐，而无需手动移动每个图形。但我不确定弄乱计数器是否会产生任何其他严重问题...
