我想使用pgfplots 绘制箱线图. 这个最小的例子对我来说很好用。
但我想以这种形式显示更多数据
\begin{filecontents}{testdata.dat}
0 1 1.2 0.4 1.5 0.2
1 2 2.3 1.5 2.7 1
2 0.7 1.4 0.5 1.9 0.1
3 1 1.2 0.4 1.5 0.2
4 2 2.3 1.5 2.7 1
5 0.7 1.4 0.5 1.9 0.1
\end{filecontents}
当我运行上面提到的这个最小示例时，我得到了接触或重叠的框。不幸的是，我不能附加图像。只需自己运行下面的示例即可。
为了考虑更多数据并删除重叠图表，我需要在提供的代码中调整什么？这个宽度可以手动调整吗？或者甚至可以选择自动执行此操作？
\documentclass{minimal}

非常感谢您的宝贵时间。

下面是一个带有新可选键的示例box plot width，可用于设置框的宽度：
\documentclass{minimal}
\usepackage{pgfplots}
\usepackage{filecontents}
\begin{filecontents}{testdata.dat}
0 1 1.2 0.4 1.5 0.2
1 2 2.3 1.5 2.7 1
2 0.7 1.4 0.5 1.9 0.1
3 1 1.2 0.4 1.5 0.2
4 2 2.3 1.5 2.7 1
5 0.7 1.4 0.5 1.9 0.1
\end{filecontents}
\pgfplotsset{
box plot width/.initial=1em,
box plot/.style={
/pgfplots/.cd,
black,

mark=-,
mark size=\pgfkeysvalueof{/pgfplots/box plot width},

y dir=plus,
y explicit,
},
box plot box/.style={
/pgfplots/error bars/draw error bar/.code 2 args={%
