![忽略轴环境中的规范](https://linux22.com/image/313834/%E5%BF%BD%E7%95%A5%E8%BD%B4%E7%8E%AF%E5%A2%83%E4%B8%AD%E7%9A%84%E8%A7%84%E8%8C%83.png)
这是我另一篇文章中的类似显示。只有两个不同之处。(其中一个不同之处是线条标签的位置。在我的文章中,我将标签放在线条上。由于 Gonzalo Medina 的评论,我现在将标签放在线条末尾。)另一个不同之处是我编辑了环境axis
以使其更简洁。我添加了
x tick label style={font=\tiny,fill=white,anchor=south,shift=-4pt}
至xticklabel style=
和
y tick label style={font=\tiny,fill=white,anchor=west,shift=-4pt}
至yticklabel style=
。为什么这些规范被忽略了?

答案1
您正在嵌套相同样式的键:出于兼容性原因,xticklabel style
和x tick label style
是同一键的缩写every x tick label/.style
。删除内部或外部即可产生效果。
编辑:为了澄清评论中的讨论,我添加了完整的 MWe 并进行了一些解释:

关于shift
:您可以声明某个物体的偏移量为shift=(x-direction,y-direction)
或 仅在 x 方向为xshif=<x-distance>
或 y 方向为yshift=<y-distance
。在您的例子中,不是shift=-4pt for shifting in x direction should be
xshif=-4pt or if you persist to use just shift: ˙
shift=(-4pt,0pt)`。
