添加额外的 y 刻度，也会在图表的另一部分添加不必要的刻度

Question

我想构建一个正态分布概率图。x 轴表示我的箱体的 x 值，y 轴显示刻度标签上的累积概率，但 y 值是相应的正态分布 z 值。我的教授使用的格式是：主网格带有标签，用于表示我的图上看到的 y 值，次网格没有标签，用于 2 到 9 和 91 到 98 的 y 值（代码中注释掉的行）。

无标签次网格是使用额外的 y 刻度实现的。但是，当我将 y 值添加为额外的 y 刻度时，会出现两条次网格线。为什么会出现它们，我该如何摆脱它们？

Answer 1

对于pgfplots，次要网格是 N 个自动放置的刻度/网格线，放置在每个主要刻度之间。主要刻度放置在指定的刻度位置。

因此，我认为您需要grid=major额外的刻度，并major grid style单独设置额外的刻度：

extra y tick style={
  tick style={draw=none},
  grid=major,
  major grid style={line width=.2pt,draw=red!120}
},
