如何使用 minipage 调整图片之间的间距？

我使用 minipages 放置了三个图表，但是每两个图表之间的间距宽度不一样。这是代码，有人能帮我吗？如何将 (a) (b) (c) 定位在每个图表上方？

答案1

不同空间的原因与以下用途有关minipage：您定义了固定宽度的块，而这些块内的图片不会填满整个块，而是留下不同的空白空间。如果您将小页面放在一个\fbox{...}块中，就可以看到它们。

你最好看看子字幕包\hspace{dimension}或者使用如下方式手动定位空格：

\begin{tikzpicture}
% picture A
\end{tikzpicture}
\hspace{5mm}
\begin{tikzpicture}
% picture B
\end{tikzpicture}

编辑：子标题包的使用
