如何对齐 pgfplots 中的图例？

Question

mwe 是

\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
  \begin{axis}
    \addplot coordinates {(0,0) (1,1)};
    \addlegendentry{Short Legend}
    \addplot coordinates {(0,1) (1,2)};
    \addlegendentry{Very very long Legend}
  \end{axis}
\end{tikzpicture}
\end{document} 

两个图例的长度不同，并且它们垂直居中对齐。现在我想将图例左对齐。我该怎么做？

Answer 1

您只需要添加到轴选项：（legend cell align=left参见包 PGFPLOTS 手册，第 255 页）：

\documentclass[tikz,margin=3mm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[legend cell align=left]% <--- added 
    \addplot coordinates {(0,0) (1,1)};
    \addlegendentry{Short Legend}
    \addplot coordinates {(0,1) (1,2)};
    \addlegendentry{Very very long Legend}
  \end{axis}
\end{tikzpicture}
\end{document}
