我正在尝试修改我的箱线图

Question

coordinates {...}需要手动坐标列表，而不是文件名。.csv可以通过加载文件table[col sep=comma] {file.csv}。

深绿色线条可以用绘制\draw。坐标（尤其是值y）可通过坐标系获得axis cs:，左右边界可通过节点获得current axis。

完整示例：

\documentclass{standalone}   
\usepackage[svgnames]{xcolor}
\usepackage{pgfplots}   
\pgfplotsset{compat=1.8}
\usepgfplotslibrary{statistics}

\begin{document}

\begin{tikzpicture}
  \begin{axis}
    [
    boxplot/draw direction=y,
    xtick={1,2},
    xticklabels={Arm,Focal}
    ]

    % Horizontal dark green lines
    \draw[DarkGreen, dashed]
      (axis cs:0, 1.5) coordinate (tmp)
      (current axis.west |- tmp) -- (current axis.east |- tmp)
      (axis cs:0, 0.1) coordinate (tmp)
      (current axis.west |- tmp) -- (current axis.east |- tmp)
    ;

    \addplot+[
    boxplot prepared={
      lower whisker=0.1036, 
      lower quartile=0.1141,
      median=0.1301,
      upper quartile=0.2035,
      upper whisker=0.4313
    },
    ] table[col sep=comma] {ArmAmpRemaining.csv};
     \addplot+[
    boxplot prepared={
      median=0.2402,
      upper quartile=0.4032,
      lower quartile=0.1616,
      upper whisker=4.1380,
      lower whisker=0.1001
    },
    ] table[col sep=comma] {FocalAmpRemaining.csv};

  \end{axis}
\end{tikzpicture}
\end{document}

包还可以通过而不是pgfplots自动计算箱线图的值。还可以启用平均值计算。异常值会自动识别和显示。以下示例使用与问题相同的数据（其余点作为完整数据集），只是它将两个点（0，0.105）和（0，0.11）添加到。该示例还将计算出的值打印到屏幕和日志文件中。特殊坐标系如或可用于注释箱线图，请参阅boxplotboxplot preparedArmAmpRemaining.csvboxplot box cs:boxplot whisker cs:手动的了解pgfplots详情。

计算值为：

Box plot values:
* lower whisker = 4.23168e-4
* lower quartile = 9.4510461e-3
* median = 2.0015736e-2
* upper quartile = 4.7414362e-2
* upper whisker = 9.2048857e-2
* average = 3.1158e-2

Box plot values:
* lower whisker = 3.18542e-4
* lower quartile = 2.0696782e-2
* median = 4.6548923e-2
* upper quartile = 7.2519682e-2
* upper whisker = 9.9210585e-2
* average = 4.6918e-2
