垂直曲线之间的阴影

Question

如何在垂直曲线和水平线之间进行$x=1-y^2$阴影$x=y^3-y$处理$y=0.7$ 和 $y=-0.5$？

      ymin=-1.5,ymax=1.5,
      xlabel=$x$, 
      ylabel=$y$,
axis labels at tip,
      xtick={-2,...,2},
      ytick={-2,...,2},
] 
\addplot [name path=E,very thick,DodgerBlue4,domain=-0.7:0.9,samples=200] ({1-x^2},{x});
\addplot [name path=D,very thick,Chartreuse4,domain=-0.7:0.9,samples=100] ({x^3-x},{x});
\addplot[name path=A,mark=none,gray] coordinates {(0.51,0.7) (-0.357,0.7)};
\addplot[name path=B,mark=none,gray] coordinates {(0.75,-0.5) (0.375,-0.5)};
  \end{axis}
  \end{tikzpicture}
\end{document}

欢迎！您可以使用密钥执行此操作soft clip={domain y=-0.5:0.7}，

\addplot[red!20] fill between[of=E and D,soft clip={domain y=-0.5:0.7}];
