在此图中，我的两个 x 标签与函数重叠。我想将标签移到顶部，或者给它们一个白框？不知道哪种看起来更好。
我怎样才能做到这一点？

答案1
由于您尚未说明如何处理两个重叠的 x 刻度标签C1和C2，我会即兴发挥。我添加了图钉以避免重叠问题，用于clip=false确保这些图钉可见，改进了附在是轴：
$\operatorname{\Delta}\bigl(\operatorname{E}[\pi]\bigr)$
（使用\operatornamefromamsmath获得适当的间距和直立的字体），删除未使用的东西 - 包括许多不必要的行尾百分号 - 在垂直线左侧十点处放置一个带有方程的图例框X = 瓦S 2 *，用于every axis plot/.append style={myplot}避免重复每个图的样式，并从中myplot删除：+\addplot+
我们不想在这里使用任何标记来表示情节，并且
我们自己指定每个图的颜色。
另外，标题的位置不合适，看起来很糟糕。我已将其figure以标准方式添加到：
\caption{Effect of financial distress on expected profits}
您可能想要添加：
\label{whatever-you-want}
紧接着这一行之后（以前没有！）。最后，我在的参数中设置了compat=1.16而不是，以确保可重现的行为。compat=newest\pgfplotsset

随着X顶部轴线
代码是相同的，只是你必须用和axis x line=bottom替换axis x line=top
\node [pin=-100:$c_1$] at (0.2,0 |- {axis description cs:0,0}) {};
\node [pin=-80:$c_2$] at (0.22,0 |- {axis description cs:0,0}) {};
和
\node [pin=100:$c_1$] at (0.2,0 |- {axis description cs:0,1}) {};
\node [pin=80:$c_2$] at (0.22,0 |- {axis description cs:0,1}) {};
