ybar 间隔和图上的线

Question

如何去除此图中每条柱状图两侧的垂直线？我认为它们的出现是由于ybar interval我需要该命令xticklabel。

\documentclass[margin=1cm]{standalone}
\usepackage{pgfplots}
\usepackage{filecontents}
\begin{filecontents}{foo.csv}
n,o
46,7
89,10
96,35
100,66
32,60
8,10
43,136
44,154
90,115
88,161
10,145
7,82
8,96
31,88
9,51
6,177
38,174
50,52
32,14
44,50
17,187
\end{filecontents}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[
    ybar interval,
    xticklabel=\rotatebox{90}{\pgfmathprintnumber\tick--\pgfmathprintnumber\nexttick},
    xtick style={draw=none},
    ymin=0
    ]
\addplot+ [hist={data=x}] table [x=o,col sep=comma] {foo.csv};
\end{axis}
\end{tikzpicture}
\end{document}

Answer 1

只需添加grid=none到axis选项中即可。
