具有共同 y 轴的多个 pgfplots

Question

作为手稿的一部分，我必须绘制 x 轴和 y 轴范围相同的多个图形。我正在使用 subflot 和 tikzpicture。我的问题是，由于两个轴的值范围相同，因此可以消除 y 轴，并排绘制所有图形，其中 x 轴单独，y 轴共用。每个图形都有散点图和线图（实际数据和拟合数据）。手册中提到了堆叠图，但这不是我想要的。请帮帮我。

Answer 1

如果你希望它像你的图像中那样，那么使用 就不再有意义了subfig。这里有一种方法可以做到：

\documentclass[tikz, border=1cm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\pgfplotsset{legend pos=north west, ymin=-10, ymax=400}
\begin{document}
\begin{tikzpicture}

\begin{axis}[
name=plot1,
ytick pos=left,
xlabel={$y$}, ylabel={$y'$},
]
\addplot[very thick][domain=25:350, samples=2]{(1.114938029*x)+(-16.01)};
\legend{$\, Y_1$}
\end{axis}

\begin{axis}[
name=plot2, at={(plot1.south east)},
ytick=\empty,
xlabel={$y$},
]
\addplot[orange, very thick][domain=25:350, samples=2]{(0.96*x)+(5.98)};
\legend{$\, Y_2$}
\end{axis}

\begin{axis}[
name=plot3, at={(plot2.south east)},
ytick=\empty,
xlabel={$y$},
]
\addplot[teal, very thick][domain=25:350, samples=2]{(0.96*x)+(6.00)};
\legend{$\, Y_3$}
\end{axis}

\end{tikzpicture}
\end{document}
