子图直方图的对齐问题

Question

我在子图绘图中遇到了对齐问题，我不知道该如何解决它，我尝试将主题设为图像，但遇到了同样的问题。主要问题如下图所示。如图所示，图形未对齐，或者大小不相同（标题/标题也是如此）。绘图是通过 pgfplots 和 subfig 包制作的。用于生成它们的代码位于本文末尾。欢迎任何帮助！！！

编辑：主要错误 独立类如图

Answer 1

有几个问题：

• 您的图表宽度不同，因为有些图表有 x 标签，而有些没有。如果您缩放它们（你不应该对包含文本的元素这样做) 的宽度相同，它们的高度将不再匹配。您可以通过对其他图表使用虚拟标签来避免这种情况。

• 空行和其他空白区域非常重要！如果代码中存在空行，则图像之间会强制换行，所有未受保护的行尾都会充当空白区域。
