晚上好，
我现在已经完成了六张图表。但是还有一些问题我还没能解决。
- 如您所见，u_GR 似乎大于 u_2，但从物理上讲，这是不可能的。当然，一旦我添加标签，这一点就会很清楚，但我想让它们看起来大小相等。我知道这是由于 u_2 中的负值造成的。
- 关于标签，什么是“最佳”（即最好看）的标签制作方法？如果是我，我会定义一堆节点（例如，在 (0,1) 处为 u_GR 并将其标记为 U_something。有没有自动化的方法来实现这一点？
- 有什么建议我应该做什么来增强图表？
多谢。

答案1
像这样的样子？
关于你的子问题：
- 在所有 y 标签中都使用相同的字体大小，但由于使用的字母不同，标签的显示效果可能会有所不同，例如，
u并且U具有（本来就是）不同的高度 :-) - 如果添加文档序言，标签的显示效果会更好
\usepackage[low-sup]{subdepth}（它会将变量索引推得更低，参见上图，并比较删除此包后的结果） xtick我会考虑给出的风格建议我的答案关于你之前的一个问题
