YComb 展开多根棍子

我有以下图表：

\usepackage{pgfplots}

\begin{tikzpicture}
\begin{axis}[y dir = reverse,
     width=12cm,
     height=10cm, 
     xtick={1,...,6}, 
     ytick={-1,...,-1000},
     ymax=-600,
     xlabel = Number of tasks trained,
     ylabel = Cost
     ]
\addplot+[ycomb, very thick] coordinates {(1, -612) (2, -612)   (3, -611) (4,-611) (5, -611)};
\addplot+[ycomb, very thick] coordinates {          (2, -611.5) (3, -611) (4,-611) (5, -610.5)};
\addplot+[ycomb, very thick] coordinates {                      (3, -612) (4,-611) (5, -610.9)};
\addplot+[ycomb, very thick] coordinates {                                (4,-613) (5, -613)};
\addplot+[ycomb, very thick] coordinates {                                         (5, -612.5)};
\end{axis}
\end{tikzpicture}

问题是所有梳状图的条形图都重叠了。有没有办法像条形图一样将它们展开？

答案1

半自动，xshift每个添加一个\addplot：

在此处输入图片描述

\documentclass[border=3mm]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[y dir = reverse,
     width=12cm,
     height=10cm, 
     xtick={1,...,6}, 
     ytick={-1,...,-1000},
     ymax=-600,
     xlabel = Number of tasks trained,
     ylabel = Cost
     ]
\addplot+[ycomb, very thick,xshift=-4mm] coordinates {(1, -612) (2, -612)   (3, -611) (4,-611) (5, -611)};
\addplot+[ycomb, very thick,xshift=-2mm] coordinates {          (2, -611.5) (3, -611) (4,-611) (5, -610.5)};
\addplot+[ycomb, very thick] coordinates {                      (3, -612) (4,-611) (5, -610.9)};
\addplot+[ycomb, very thick,xshift=2mm] coordinates {                                (4,-613) (5, -613)};
\addplot+[ycomb, very thick,xshift=4mm] coordinates {                                         (5, -612.5)};
\end{axis}
\end{tikzpicture}
\end{document}
