我需要你的帮助。我遇到了一个问题，困扰了我好几天，但还是找不到解决办法。
我想将三张图表并排放置。
所有图表都应具有相同的 x 轴标签、y 轴标签和图例。也就是说，不是每个图表都单独使用一个，而是使用一个全局轴标签。
编辑：
- 所有三个 y 轴的比例相同，只需要一个全局图例（和值）。
-x 轴值应该保留，但标签（R）应该是全局的。
-每个图表中可以有多个绘图，因此如果图例在三个图表上齐平会更好。
编辑2：
有一个小瑕疵。是否可以将图例（大量文本）与左右两侧的图表完全齐平？（请参阅我的示例代码！）

答案1
只是对 OP 代码的第一次测试。每个情节都是独立的tikzpicture，并且根据其对齐baseline。
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{width=6cm,height=6cm}
\begin{document}
\begin{figure}

第二种选择：所有地块都具有相同的 inte tikzpicture，并根据其“节点”锚点对齐，name每个地块都有一个固定的选项。此解决方案显示在groupplots库部分中。
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{width=6cm,height=6cm}
\usetikzlibrary{calc}
\begin{document}
\begin{figure}
\centering

\begin{axis}[name=leftplot, width=0.3\textwidth,height=0.2\textheight,
grid=major,
cycle list name=color,
ylabel={R},
% xlabel={x},
ylabel near ticks,
]
\addplot coordinates {(1,6.45)(2,3.4)(3,4.8)(4,4.1)(5,4.4)};
\end{axis}
\begin{axis}[name=middleplot, at ={($(leftplot.east)+(1cm,0)$)}, anchor=west,

\addplot coordinates {(1,6.45)(2,3.4)(3,4.8)(4,4.1)(5,4.4)};
\end{axis}
\end{tikzpicture}

\end{figure}
\end{document}
第三种选择：使用groupplots库
\documentclass{article}
\usepackage{pgfplots}
\usepgfplotslibrary{groupplots}
\pgfplotsset{width=6cm,height=6cm}
\usetikzlibrary{calc}
\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}[baseline=(current axis.south)]
\begin{groupplot}[%
group style={%
group size=3 by 1,
},
width=0.3\textwidth,height=0.2\textheight,
grid=major, cycle list name=color, ylabel near ticks,
legend style={at={(0.5,1.05)}, anchor=south, legend columns=3, column sep=6pt}
]
\nextgroupplot[ylabel={R}]
\addplot coordinates {(1,6.45)(2,3.4)(3,4.8)(4,4.1)(5,4.4)};
\nextgroupplot[xlabel={x}]
\addplot coordinates {(1,6.45)(2,3.4)(3,4.8)(4,4.1)(5,4.4)};
\addlegendentry{1};
\addlegendentry{2};
\addlegendentry{3};
\addlegendentry{4};
\addlegendentry{5};
\addlegendentry{6};
\nextgroupplot
\addplot coordinates {(1,6.45)(2,3.4)(3,4.8)(4,4.1)(5,4.4)};
\end{groupplot}
\end{tikzpicture}
\end{figure}

更新：与图例边距对齐
为了将第一和第三个图与长图例边框对齐，最简单的方法是先绘制中心图，然后使用outer锚点（图例定义它们）来固定横向图。
