删除 groupplot 中的 xticks

Question

有没有办法去掉下面组图中第一和第二个图之间的 xticks 以及第二和第三个图之间的 xticks？去掉每个图内部的 xticks（例如从 0 向上延伸的刻度）就可以了。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots, pgfplotstable}
\usepgfplotslibrary{groupplots}
\pgfplotstableread{
wk  1   2   3
0   2   3   4
1   5   6   7
2   0   0   0
3   5   6   7
}\data
\begin{document}
\begin{tikzpicture}
  \pgfplotsset{group/vertical sep={0cm},
    group/x descriptions at=edge bottom,
  }
  \begin{groupplot}[group style={group size=1 by 3},
                    height=5cm,
                    width=8cm,
                    ybar stacked,
                    xtick=data,
                    ymin=0,
                    xticklabels from table={\data}{wk},
                    tick align=outside
                    ]
    \nextgroupplot
      \addplot [fill=black!60] table [y=1, x expr=\coordindex] {\data};    
      \addplot [fill=black!20] table [y=2, x expr=\coordindex] {\data};
      \addplot [fill=black!40] table [y=3, x expr=\coordindex] {\data};
    \nextgroupplot
      \addplot [fill=black!60] table [y=1, x expr=\coordindex] {\data};    
      \addplot [fill=black!20] table [y=2, x expr=\coordindex] {\data};
      \addplot [fill=black!40] table [y=3, x expr=\coordindex] {\data};
    \nextgroupplot
      \addplot [fill=black!60] table [y=1, x expr=\coordindex] {\data};    
      \addplot [fill=black!20] table [y=2, x expr=\coordindex] {\data};
      \addplot [fill=black!40] table [y=3, x expr=\coordindex] {\data};
\end{groupplot}
\end{tikzpicture}
\end{document}
