pgfplots - 如何在组图中仅打印一次 y 刻度标签？

我想只打印 y 轴的刻度标签一次在 groupplot 中。这对于使用以下选项的情况非常有用：

ylabels at=edge left,
yticklabels at=edge left,

这可能吗？

这似乎是groupplots库中的一个疏忽。修复此行为所需的更改并不复杂（只需一行代码），但它会影响一个非常长的内部宏。

要修复该库，请将以下代码放入您的序言中：

仅作为一种解决方法：您可以scaled y ticks=true手动设置左侧图的选项：

\documentclass{scrartcl}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usepgfplotslibrary{groupplots}
\begin{document}
\begin{center}
\begin{tikzpicture}[font=\small]
\begin{groupplot}[
  group style={
    group size=4 by 4, %4 column(s), 4 row(s)% 
    horizontal sep=0cm,
    vertical sep=1.5cm,
    ylabels at=edge left,
    yticklabels at=edge left,
  },
  xlabel={Bla},
  ylabel={Process},
  %
  x tick scale label style={
    at={(0.95,0)},yshift=-1.5em,anchor=north,inner sep=0pt
  },
  y tick scale label style={
    at={(-0.05,0.99)},anchor=east,inner sep=0pt,
  },
  scale ticks above exponent={2},
  scaled y ticks=false% <-
]
\nextgroupplot[scaled y ticks=true]% <-
\addplot[only marks] coordinates{(1,1200) (3,500)};
\nextgroupplot
\addplot[only marks] coordinates{(2,1200) (4,400)};
\end{groupplot}
\end{tikzpicture}
\end{center}
\end{document}

但是 groupplot 中还存在其他问题：左侧图和右侧图的刻度位置不同。groupplot 比 更宽\linewidth。页面上没有足够的空间容纳 4x4 groupplot。此外，我会在两个图之间插入一个小的水平分隔符。

\documentclass{scrartcl}
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11}
\usepgfplotslibrary{groupplots}

\begin{document}
\begin{center}
\begin{tikzpicture}[font=\small]
\begin{groupplot}[
  group style={
    group size=2 by 2, %2 column(s), 2 row(s)% <-
    horizontal sep=5pt,
    vertical sep=1.5cm,
    ylabels at=edge left,
    yticklabels at=edge left,
  },
  width=.55\linewidth,% <-
  xlabel={Bla},
  ylabel={Process},
  %
  x tick scale label style={
    at={(0.95,0)},yshift=-1.5em,anchor=north,inner sep=0pt
  },
  y tick scale label style={
    at={(-0.05,0.99)},anchor=east,inner sep=0pt,
  },
  ymin=400,ymax=1200,enlarge y limits=.1,% <-
  scale ticks above exponent={2},
  scaled y ticks=false% <-
]
\nextgroupplot[scaled y ticks=true]% <-
\addplot[only marks] coordinates{(1,1200) (3,500)};
\nextgroupplot
\addplot[only marks] coordinates{(2,1200) (4,400)};
\end{groupplot}
