Tikz error with simple Lineplot with legend

Question

I try to plot a line from the file "aLinePlot.tex" which is automatically generated via matlab2tikz:

\addlegendentry{legend1}

\end{axis}
\end{tikzpicture}%

With the following minimal Example I get the error "Undefined control sequence. \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}

As i am not really familiar with tikz, can someone give me a hint how to solve this problem? Btw: Compiler is PdfLatex on a linux machine

Answer 1

Your editor doesn't help you when it parses the .log file, the error says

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

l.73 \end{axis}

? 

which means that \miniscule is the undefined control sequence.

\miniscule is a font size switch that isn't defined in the standard classes, but it is defined in the memoir class. So either change the documentclass to memoir, or modify

legend style={font=\miniscule}

to for example

legend style={font=\tiny}

Working code:

\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},                     
}}

\pgfplotsset{compat=newest}
\pgfplotsset{plot coordinates/math parser=false}

\newlength\fheight % not used in this example
