虚线作为 pgfplots 中的标记

Question

我正在尝试将这个图中的某些标记变成虚线。但是，我只能一次更改它们。我需要“a”、“b”和“c”保持为实线，并将“d”和“e”变成虚线。最好用花括号标记“d”和“e”之间的分隔，如下所示。我该怎么做？

代码：

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.15}
\begin{document}
\begin{tikzpicture}
 \begin{axis}[
   every axis plot post/.style={mark=-,thick,mark size=10mm},
   xtick style={draw=none},
   xticklabels={,,},
   xmin=-0.9,
   xmax=1.1,
   ymin=14.5,
   ymax=19.5,
   cycle list name=black white,
   only marks, 
   x=2cm, y=1cm,
   every node near coord/.append style={font=\small,yshift=-2.5mm,xshift=\myshift}
 ]
\addplot [nodes near coords={\labelz},
visualization depends on={value \thisrowno{2}\as\labelz},visualization depends on={value \thisrowno{3}\as\myshift}] 
table[header=false] {
0 15.152 a 15mm
0 18.182 b 15mm
0 18.868 c 15mm
0 18.943 d -15mm
0 18.107 e -15mm
};
\end{axis}
\end{tikzpicture}
\end{document}

我设法做到了这一点，但不确定这是否是最好的解决方案：

\documentclass{standalone}
\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{decorations.pathreplacing}
\pgfplotsset{compat=1.15}
\begin{document}
\begin{tikzpicture}
 \begin{axis}[
   xtick style={draw=none},
   xticklabels={,,},
   xmin=-0.9,
   xmax=1.1,
   ymin=14.5,
   ymax=19.5,
   cycle list name=black white,
   only marks, 
   x=2cm, y=1cm,
   every node near coord/.append style={font=\small,yshift=-2.5mm,xshift=\myshift}
 ]
\addplot [mark=-,thick,mark size=10mm,nodes near coords={\labelz},
visualization depends on={value \thisrowno{2}\as\labelz},visualization depends on={value \thisrowno{3}\as\myshift}] 
table[header=false] {
0 15.152 a 15mm
0 18.182 b 15mm
0 18.868 c 15mm
};
\addplot [mark=-,thick,dashed,mark size=10mm,nodes near coords={\labelz},
visualization depends on={value \thisrowno{2}\as\labelz},visualization depends on={value \thisrowno{3}\as\myshift}] 
table[header=false] {
0 18.943 {} -15mm
0 18.107 {} -15mm
};
\draw [decorate,decoration={brace,mirror}]
(-0.55,18.943) -- (-0.55,18.107) node [midway,xshift=-5mm] {d};
\end{axis}
\end{tikzpicture}
\end{document}
