带有图例的简单线图出现 Tikz 错误

我尝试从通过 matlab2tikz 自动生成的文件“aLinePlot.tex”中绘制一条线：

使用以下最小示例，我收到错误“未定义的控制序列。\end{axis}

\documentclass[10pt,a4paper]{article}
\usepackage[latin1]{inputenc}

\usepackage{pgfplots}
\pgfplotsset{every axis/.append style={
        label style={font=\footnotesize },
        label style={font=\footnotesize },
        tick label style={font=\footnotesize},  
        legend style={font=\miniscule},                     
}}

\usepackage{tikz}
\pgfplotsset{compat=newest}
\pgfplotsset{plot coordinates/math parser=false}
\newlength\fwidth
\newlength\fheight % not used in this example

\begin{document}

    \begin{figure}[htb]
        \begin{center}
            \setlength{\fwidth}{.7\linewidth} 
            \input{aLinePlot.tex}
            \label{fig:someLabel}
            \caption{some Caption}
        \end{center}
    \end{figure}

\end{document}

由于我对 tikz 不太熟悉，有人能给我提示如何解决这个问题吗？顺便说一句：编译器是 Linux 机器上的 PdfLatex

答案1

您的编辑器在解析文件时没有帮助您.log，错误显示

! Undefined control sequence.
\tikz@textfont ->\miniscule 

l.73 \end{axis}

?

这意味着这\miniscule是未定义的控制序列。

\miniscule是标准类中未定义的字体大小开关，但它在memoir类中定义。因此，要么将 documentclass 更改为memoir，要么修改

legend style={font=\miniscule}

例如

legend style={font=\tiny}

工作代码：

\documentclass[10pt,a4paper]{memoir} % <-- changed article to memoir
\usepackage[latin1]{inputenc}

\usepackage{pgfplots}
\pgfplotsset{every axis/.append style={
        label style={font=\footnotesize },
        label style={font=\footnotesize },
        tick label style={font=\footnotesize},  
        legend style={font=\miniscule},                     
}}
