使用 groupplots 时如何设置两种类型的图的轴限制

Question

我有一个相当大的图形，有两行图，第一行有一个 y 轴，第二行有另一个 y 轴。我想为这两组 y 轴设置轴限值，而不必\nextgroupplot[ymin=###,ymax=###]为每个图都写一个，例如使用，\pgfplotsset{group/every plot/.style={ymin=###,ymax=###}}但这似乎不起作用。

这是我想要实现的一个例子

\documentclass{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{groupplots}
\begin{document}
\begin{tikzpicture}
\begin{groupplot}[group style={group size=3 by 2,every plot/.style={xmin=0,xmax=10}},width=4cm,height=6cm]

\nextgroupplot[ylabel={Quantity1 [unit1]},ymin=0,ymax=5,title={First conditions}]
\addplot {x};
\nextgroupplot[ymin=0,ymax=5,title={Second conditions}]
\addplot {x};
\nextgroupplot[ymin=0,ymax=5,title={Third conditions}]
\addplot {x};

\nextgroupplot[ylabel={Quantity2 [unit2]},ymin=100,ymax=400]
\addplot {400/x^.5};
\nextgroupplot[ymin=100,ymax=400]
\addplot {400/x^.5};
\nextgroupplot[ymin=100,ymax=400]
\addplot {400/x^.5};
\end{groupplot}
\end{tikzpicture}
\end{document}

这使：

以下是尝试简化的代码（并更正了 LaRiFaRi 的评论）：

\documentclass{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{groupplots}
\begin{document}
\begin{tikzpicture}
\begin{groupplot}[group style={group size=3 by 2,every plot/.style={xmin=0,xmax=10}},width=4cm,height=6cm]
\pgfplotsset{group/every plot/.append style={ymin=0,ymax=5}}
\nextgroupplot[ylabel={Quantity1 [unit1]},title={First conditions}]
\addplot {x};
\nextgroupplot[title={Second conditions}]
\addplot {x};
\nextgroupplot[title={Third conditions}]
\addplot {x};

\pgfplotsset{group/every plot/.style={ymin=100,ymax=400}}
\nextgroupplot[ylabel={Quantity2 [unit2]}]
\addplot {400/x^.5};
\nextgroupplot
\addplot {400/x^.5};
\nextgroupplot
\addplot {400/x^.5};
\end{groupplot}
\end{tikzpicture}
\end{document}

但不幸的是，这会弄乱第二组图的轴。还有其他方法可以设置多个图的轴限值吗？

Answer 1

我想说这不是一个错误，而是一个功能。使用\pgfplotsset 后第一个\nextgroupplot（很可能）与使用那个相同里面环境的范围 axis，因此仅限于此。我说过，我还建议开始一个新groupplot环境。关于“重复”选项：只需创建一个收集所有共同点的样式，并将差异应用于每个新groupplot环境。
