在下面的代码中，当我尝试执行软剪辑命令时\addplot [red, fill opacity=0.1] fill between[of=C and D,soft clip={domain=0:0.6336}]，我的输出文件显示为空白，仅显示页码。有没有更简单的方法用红色填充第二个图中 100 以上和 -100 以下的区域，因此该图如下所示：

答案1
有一些fill between问题groupplots例如pgfplots 中的 fillbetween 在 groupplots 中不起作用，或许还存在一些问题。
作为一种解决方法，您可以使用与如何根据轴的值突出显示 Pgfplots 图中的区域？，即添加 \usetikzlibrary{backgrounds}，并添加
\begin{scope}[on background layer]
\fill [red!20] (0,100) rectangle (0.7,500);
\fill [red!20] (0,-100) rectangle (0.7,-500);
\end{scope}
在axis环境中：
