突出显示自定义图表的特定部分

Question

我想突出特定的部分，比如这，用于我的图表（见下面的代码）。但在我的例子中，突出显示（来自上面的链接）不起作用。特定的自定义图表元素来自这里。

\documentclass[border=5pt, xcolor=dvipsnames]{standalone}

\tikzset{

        decoration={
            markings,
            mark=at position 0.5 with 
                {\draw (0,0) arc (0:180:#1) (0,0) arc (180:360:#1);}
        },
        postaction=decorate
    },
    myneg/.default=6pt,
    mynode/.style={
        draw,
        circle,
        minimum size=20pt
    }

                        \node at (\nodename) [draw=none,name=hullnode\counter] {};
                }
                \node at (hullnode\numberofnodes) [name=hullnode0,draw=none] {};
                \pgfmathtruncatemacro\lastnumber{\numberofnodes+1}
                \node at (hullnode1) [name=hullnode\lastnumber,draw=none] {};

        create hullnodes

    let \p1 = ($(hullnode\currentnode)!#2!-90:(hullnode\previousnode) - (hullnode\currentnode)$),
        \n1 = {atan2(\x1,\y1)},
        \p2 = ($(hullnode\currentnode)!#2!90:(hullnode\nextnode) - (hullnode\currentnode)$),
        \n2 = {atan2(\x2,\y2)},
        \n{delta} = {-Mod(\n1-\n2,360)}
    in 
        {arc [start angle=\n1, delta angle=\n{delta}, radius=#2]}
}

下面是图表的代码，我想突出显示其中的特定部分：

                {\draw (0,0) arc (0:180:#1) (0,0) arc (180:360:#1);}
        },
        postaction=decorate
    },
    myneg/.default=6pt,
    mynode/.style={
        draw,
        circle,
        minimum size=20pt
    }
}
