Graphics, Figures & Tables ⇒ Fill Between Again (I know.. I am trying)

[coachbennett1981]

I got the right area, but the axis is covered. I have tried a soft clip with fill between using the points of intersection (5pi/6 and pi/6), but that does not work. I have used Stefan's reference book and another to look some things up, but I can't get the axis to show. Any help is appreciated.

Code: Select all

\documentclass[border=5mm]{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\usepgfplotslibrary{fillbetween}
\usetikzlibrary{backgrounds,arrows.meta}
\pgfplotsset{
    interpret as polar/.style={
            x filter/.code=\pgfmathparse{cos(rawx)*rawy},
            y filter/.code=\pgfmathparse{sin(rawx)*rawy}
        }
}
\begin{document}
\begin{tikzpicture}[>=Triangle]
\begin{axis}[
            xtick distance=2,
            ytick distance=2,
            axis lines=center,
            axis equal image,
            enlargelimits=true,
        ]
    \addplot[name path=A,
            very thick,
            domain=0:360,
            samples=100,
            smooth,
            interpret as polar
        ] 
        (x,{1+sin(x)});
    \addplot[name path=B,
            very thick,
            domain=0:360,
            samples=100,
            smooth,
            interpret as polar
        ]
         (x,{3*sin(x)});
    \path[name path=xaxis] (axis cs: -1,0) -- (axis cs:1,0);
    \addplot[blue,opacity=0.5] fill between[of=B and A];  
    \node[anchor=center,label=north west:\(R\)] at (0,0){};
     \addplot[white] fill between[of=A and xaxis];
\end{axis}
\end{tikzpicture}
\end{document}
\end{document}

Just use the option "axis on top" for the axis environment, so the axis lines are drawn over the plot.
