当我写的时候test\e，图表是这样的：

我该如何解决这个问题？帮帮我:(

\documentclass[border=2mm]{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=1.14}
\newcommand{\myequalsymbol}{      
\hspace{1.1mm}\tikz[baseline, line width=0.7 pt, line cap=round]{
  \draw (1.1,0.13) -- ++(0.22,0);
  \draw (1.1,0.06) -- ++(0.22,0);
}
\hspace{1.1mm}}
\newcommand{\e}{\myequalsymbol}
\begin{document}
\begin{tikzpicture}[]
\begin{axis}[clip mode=individual,
xmin=5, xmax=15, ymin=22, ymax=60,
]
\addplot[domain=4:14]{16.46/3.6*x}; 
\path (6, {16.46/3.6*6}) --  (14, {16.46/3.6*14}) node [at end,anchor=south east,sloped] () {test\e};
\end{axis}
\end{tikzpicture}
\end{document}

如果您的符号是数学关系，您应该用它定义它以\mathrel在之前和之后有正确的间距=。

为了避免嵌套的 TikZ 图片，您可以使用一个盒子。

\documentclass[border=2mm]{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{amsmath}
\pgfplotsset{compat=1.14}
\newbox{\myequalsymbol}
\savebox{\myequalsymbol}{\tikz[baseline, line width=0.7 pt, line cap=round]{
  \draw (1.1,0.13) -- ++(0.22,0);
  \draw (1.1,0.06) -- ++(0.22,0);
}}
\newcommand{\e}{\mathrel{\usebox{\myequalsymbol}}}
\begin{document}
\begin{tikzpicture}[]
\begin{axis}[clip mode=individual,
xmin=5, xmax=15, ymin=22, ymax=60,
]
\addplot[domain=4:14]{16.46/3.6*x}; 
\path (6, {16.46/3.6*6}) --  (14, {16.46/3.6*14}) node [at end,
anchor=south east, sloped, xshift=3pt,
] {$\text{test}\e$};
\end{axis}
\end{tikzpicture}
\end{document}
