我正在尝试将这两个图形与 x 轴对齐。我尝试过迷你页面，但没有成功。我也尝试过操作 ( \myplotB)，但失败了。我到处找了找。任何帮助我都感激不尽。

答案1
s的垂直对齐tikzpicture可以通过选项实现baseline：通过baseline=0强制图片 x 轴与周围文本的基线对齐，而默认情况下，图片下边框与文本对齐。
因此，第一步是将此选项添加baseline=0到您的两个tikzpicture环境中。
不幸的是，在这种情况下这还不够，因为你tikzpicture的 x 轴不是你的图的 x 轴。
我对的内部结构一无所知pgfplot，但如果地块恰好是节点，那么它们的位置也可以进行调整：重新定义节点的锚点可以在垂直放置方面有一定的自由度。
在您的情况下，以下修改通过锚定图的中心原点（编辑）直指(0,0)要点：
\newcommand{\myplotB}[1]{
\begin{tikzpicture}[baseline=0]
（第 13 行）和
\begin{tikzpicture}[baseline=0]
\begin{axis}[anchor=origin,
grid style={blue!50},
（第 31 和 32 行）。
请注意，这仅当 y 轴上的最小值和最大值是对称的时才有效。（编辑：不再相关）
