来自内联文件的 PGFPLOTS 箱线图数据

Question

我有以下代码：

\documentclass{article}
\usepackage{filecontents}
\usepackage{pgfplots, pgfplotstable}
\usepgfplotslibrary{statistics} 

\begin{document}

\pgfplotsset{width=7cm,compat=1.10}

\pgfplotstableread{
%\begin{filecontents}{test.dat}
miles
1
2
1
5
4
10
7
10
9
8
9
9
%\end{filecontents}
}\mytable

\pgfplotstablegetrowsof{\mytable}
\edef\numberofrows{\pgfplotsretval}

\begin{tikzpicture}
\begin{axis}[y=1.5cm,ymax=2] 
\addplot+[boxplot] table[ y index=0, row sep=newline ]{\mytable}

%\addplot+[boxplot] table[row sep=\\,y index=0]{ 
%data\\ 1\\2\\1\\5\\4\\10\\ 7\\10\\9\\8\\9\\9\\ } 
%[above] 
%node at (boxplot box cs:\boxplotvalue{lower whisker},1) {\pgfmathprintnumber{\boxplotvalue{lower whisker}}} 
%node at (boxplot box cs:\boxplotvalue{lower quartile},1) {\pgfmathprintnumber{\boxplotvalue{lower quartile}}} 
%node[left] at (boxplot box cs:\boxplotvalue{median},0.5) {\pgfmathprintnumber{\boxplotvalue{median}}} 
%node at (boxplot box cs:\boxplotvalue{upper quartile},1) {\pgfmathprintnumber{\boxplotvalue{upper quartile}}} 
%node at (boxplot box cs:\boxplotvalue{upper whisker},1) {\pgfmathprintnumber{\boxplotvalue{upper whisker}}} ; 
\end{axis} 
\end{tikzpicture}

\end{document}

编译后得到：

  ! File ended while scanning use of \pgfplots@addplotimpl@table@fromfile.

如何实现 boxplot 可以处理的内联数据表？另外，我注释掉的标签怎么样？请注意，我还注释掉了从它自己的表中读取的 boxplot。我的用法有一个内联表和几种绘图类型。我搜索了手册但没有成功。提前感谢你的帮助。戴夫

（评论太长。）

您的代码似乎运行良好，包括注释。

\documentclass{article}
\usepackage{filecontents}
\usepackage{pgfplots, pgfplotstable}
\usepgfplotslibrary{statistics} 

\begin{document}

\pgfplotsset{width=7cm,compat=1.10}

\pgfplotstableread{
%\begin{filecontents}{test.dat}
miles
1
2
1
5
4
10
7
10
9
8
9
9
%\end{filecontents}
}\mytable

\pgfplotstablegetrowsof{\mytable}
\edef\numberofrows{\pgfplotsretval}

\begin{tikzpicture}
\begin{axis}[y=1.5cm,ymax=2] 
\addplot+[boxplot] table[ y index=0, row sep=newline ]{\mytable}
node at (boxplot box cs:\boxplotvalue{lower whisker},1) {\pgfmathprintnumber{\boxplotvalue{lower whisker}}} 
node at (boxplot box cs:\boxplotvalue{lower quartile},1) {\pgfmathprintnumber{\boxplotvalue{lower quartile}}} 
node[left] at (boxplot box cs:\boxplotvalue{median},0.5) {\pgfmathprintnumber{\boxplotvalue{median}}} 
node at (boxplot box cs:\boxplotvalue{upper quartile},1) {\pgfmathprintnumber{\boxplotvalue{upper quartile}}} 
node at (boxplot box cs:\boxplotvalue{upper whisker},1) {\pgfmathprintnumber{\boxplotvalue{upper whisker}}}; 
\end{axis} 
\end{tikzpicture}

\end{document}
