我正在尝试用四张 png 图片组装一张图

我想将以下四张图片组合成一个2x2矩阵（先填充行）：

在此处输入图片描述

在此处输入图片描述 在此处输入图片描述 在此处输入图片描述

是否可以将字母 AD 放在每个图形的左下角以标记它们？谢谢！我正在学习 Latex 图形。如果我可以将其保存为 pdf，那么我可以轻松使用“图形”来创建带有标题的最终图像。

是否有可能将“每 100,000 人的费率”下的字母对齐？

答案1

至少有两种方法可以做到这一点。首先使用subcaption及其subfigure环境，然后使用 的groupplots库pgfplots。首先使用grouplots：

从subfigure上面看subcaption，它看起来像这样：
