然而这使得：

图未对齐，建议的解决方案为：

在 pgfplots 图中对齐子图 没有帮助。还有没有办法让末尾的 xtick 和 ytick 标记像在 matlab 中一样出现？或者我应该直接复制并粘贴该图？

Answer 1

pgplots只需在序言中添加此设置即可

\pgfplotsset{every axis/.append style={%
    scaled x ticks=false,
    scaled y ticks=false,
    yticklabel style={/pgf/number format/.cd,fixed,fixed zerofill,precision=1},
    xticklabel style={/pgf/number format/.cd,fixed,fixed zerofill,precision=2},
    ytick={\pgfkeysvalueof{/pgfplots/ymax},\pgfkeysvalueof{/pgfplots/ymin}},
    xtick={\pgfkeysvalueof{/pgfplots/xmax},\pgfkeysvalueof{/pgfplots/xmin}}}}

前两个选项禁止轴标签使用共同的乘积因子。

第三和第四个选项用于为所有标签设置相同的精度，以便每个图形具有相同的宽度并且对齐良好。

最后两个选项仅设置xtick相应ytick轴的最大值和最小值。
