I'm trying to set the width for all my plots, that are defined in other files and imported into the main document, using a custom width, \sz. I'm trying to set this length because I want to change it for one or two columns. Like in this example, main.tex:
\documentclass{minimal}
\usepackage{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\newlength{\sz}
\setlength{\sz}{0.5\linewidth}
\pgfplotsset{width=\sz,compat=newest}
\begin{document}
\input{test}
\end{document}
test.tex:
\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
x tick label style={
/pgf/number format/1000 sep=},
ylabel=Population,
enlargelimits=0.05,
legend style={at={(0.5,-0.15)},
anchor=north,legend columns=-1},
ybar interval=0.7,
cycle list name=color list
]
\addplot
coordinates {(1930,50e6) (1940,33e6)
(1950,40e6) (1960,50e6) (1970,70e6)};
\addplot
coordinates {(1930,38e6) (1940,42e6)
(1950,43e6) (1960,45e6) (1970,65e6)};
\addplot
coordinates {(1930,15e6) (1940,12e6)
(1950,13e6) (1960,25e6) (1970,35e6)};
\addplot
coordinates {(1930,15e6) (1940,12e6)
(1950,13e6) (1960,25e6) (1970,35e6)};
\legend{Far,Near,Here,There}
\end{axis}
\end{tikzpicture}
\end{document}
However, when I'm compiling it, the length of \sz is reset to zero. And I get the error: Error: Plot width '0.0pt' is too small. Is there any way of setting the length so that the figure in the other file is able to 'see' it?
