如何使用 pgfplots 在两个单独的图之间添加空间？

Question

我目前有以下情况：

现在你可能可以想象我并不想这样。我希望右上图与右下图对齐。但是当我使用 at 和 anchor 语句执行此操作时，图会略微下降，不再与左上图对齐。我的问题是如何解决这个问题？明确地说，我希望右上图与左上图和右下图对齐。

我有以下代码，请注意我从图中删除了数据，因为它有很多点。

Answer 1

这些没有按预期对齐的原因是第二张图没有 x 轴标签。这可以通过设置标签的宽度来实现：

\pgfplotsset{xticklabel style={text width=2em,align=right}}

得出的结果是：

参考：

• 看PGFplot 占据整个 \linewidth，并与 tikzpicture 上的 y=轴对齐

代码：
