条形图中的最小值、最大值和平均值 pgfplots

Question

我正在尝试创建一个从最小值到最大值的条形图，并带有一条平均线。到目前为止，我有一条带有最小值、最大值和平均值的线，但我希望条形更宽。有什么办法吗？

\pgfplotstableread{
x         y    y-max  y-min
AfterCoffee     17.62       26.566667   9.0
BeforeCoffee    14.42       23.0333333      8.683333  
}{\mytable}


\begin{tikzpicture}[scale=1.3] 
\begin{axis} [
    width  = 0.5*\textwidth,
    height = 8cm,
    symbolic x coords={AfterCoffee,BeforeCoffee},
    xtick=data
]
\addplot+[blue, very thick, forget plot,only marks] 
  plot[very thick, error bars/.cd, y dir=plus, y explicit]
  table[x=x,y=y,y error expr=\thisrow{y-max}] {\mytable};
\addplot+[red, very thick, only marks,xticklabels=\empty] 
  plot[very thick, error bars/.cd, y dir=minus, y explicit]
  table[x=x,y=y,y error expr=\thisrow{y-min}] {\mytable};
\end{axis} 
\end{tikzpicture}

Answer 1

您可以使用 控制误差线的格式every error bar。

只需添加

\pgfplotsset{every error bar/.style={line width=1mm}}

或者

\pgfplotsset{every error bar/.style={ultra thick}}

代码

\documentclass{article}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\begin{document}

\pgfplotsset{every error bar/.style={line width=1mm}}

\pgfplotstableread{
x         y    y-max  y-min
AfterCoffee     17.62       26.566667   9.0
BeforeCoffee    14.42       23.0333333      8.683333  
}{\mytable}


\begin{tikzpicture}[scale=1.3] 
\begin{axis} [
    width  = 0.5*\textwidth,
    height = 8cm,
    symbolic x coords={AfterCoffee,BeforeCoffee},
    xtick=data
]
\addplot+[blue, very thick, forget plot,only marks] 
  plot[very thick, error bars/.cd, y dir=plus, y explicit]
  table[x=x,y=y,y error expr=\thisrow{y-max}] {\mytable};
\addplot+[red, very thick, only marks,xticklabels=\empty] 
  plot[very thick, error bars/.cd, y dir=minus, y explicit]
  table[x=x,y=y,y error expr=\thisrow{y-min}] {\mytable};
\end{axis} 
\end{tikzpicture}
\end{document}
