如何在 TikZ 中孵化箱线图

Question

你能告诉我如何添加孵化到箱形图在TikZ？提前致谢。

\documentclass{article}

\usepackage{amsmath,amssymb,amsfonts}
\usepackage{tikz}
\usetikzlibrary{patterns}

\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\usepgfplotslibrary{statistics}

\begin{document}

\begin{tikzpicture}
  \begin{axis}
    [
    boxplot/draw direction=y,
    ylabel={Time (minutes)},
    height=6cm,
    width=6cm,
    ymin=0,ymax=11,
    cycle list={{black},{red}},
    xtick={1,2},
    xticklabels={Phase 1, Phase 2},
    ]
    \addplot+[
    fill,fill opacity=0.2,
    boxplot prepared={
      median=2.59,
      upper quartile=3.35,
      lower quartile=2,
      upper whisker=4.4,
      lower whisker=1.1
    },
    ] coordinates {};
    \addplot+[
    fill,fill opacity=0.2,
    boxplot prepared={
      median=6.57,
      upper quartile=7.93,
      lower quartile=5.93,
      upper whisker=10.68,
      lower whisker=4.03
    },
    ] coordinates {};
  \end{axis}
\end{tikzpicture}

\end{document}

解决方案是根据新手册在里面添加哈希模式描述，\addplot+[...]如下所示：

\addplot+[
    pattern={north east lines},pattern color=black,
    boxplot prepared={
      median=2.59,
      upper quartile=3.35,
      lower quartile=2,
      upper whisker=4.4,
      lower whisker=1.1
    },
    ] coordinates {};
