忽略轴环境中的规范

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？

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：

在此处输入图片描述

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 bexshif=-4pt or if you persist to use just shift: ˙shift=(-4pt,0pt)`。
