ytick 标签太小，需要分成多行

ytick 标签太小，需要分成多行

问题：我试图将 ytick 标签对齐到两行，因为标签对于数字来说看起来很小。重申一下，如下图所示，我希望在一行中输入 N=3，在另一行中添加方括号中的数字。对于 N=3、N=6、N=12、N=24、N=48 的所有 ytick 标签，应应用相同的方法。

答案1

  • 看来你的这个问题是对你之前问题的后续，你接受了（我的）答案，它的代码更清晰、简洁，结构也更好，就像你问题中的 MWE 一样。我想知道，你为什么不使用它呢？
  • 请在 MWE 问题中删除所有注释代码行。它们不会让问题更清晰，在我看来，只会分散读者的注意力。
  • 要用两行写，yticklabels您需要定义它们的样式，例如yticklabel style={align=right}。
  • 为了使两张标签不互相重叠，合理的方法是使条形图变粗，标签的基线变小。
  • 完整的 MWE，基于我的答案关于你上一个问题：

  • 不清楚第二行标签中的数据是什么意思。您可以考虑使用siunitx包并将它们（例如图 a）写成：
    yticklabels={N=3\\{[\qty{3824}{s}]},N=6\\{[\qty{11134}{s}]},N=12\\{[\qty{33443}{s}]},
                 N=24\\{[\qty{113706}{s}]},N=48\\{[\qty{432054}{s}]}}
