具有公共 y 軸的多個 pgfplot

Question

作為手稿的一部分，我必須繪製多個 x 軸和 y 軸範圍相同的圖表。我將 subflot 與 tikzpicture 一起使用。我的問題是，由於兩個軸的值範圍相同，因此可以消除 y 軸，並將所有圖形與單獨的 x 軸但共同的 y 軸並排繪製。每個圖表都有散佈圖和線圖（實際數據和擬合數據）。該手冊提到了堆疊圖，但這不是我想要的。請幫我。

如果您希望它像您想像的那樣，那麼使用 就不再有意義了subfig。這是一種方法：

\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}
