Centering a gnuplot figure properly

I use gnuplot and its epslatex terminal. When I include a gnuplot-generated figure in my document and center it as usual, it often appears shifted right — because the labels on the left contribute to the LaTeX-calculated figure width:

\documentclass[12pt]{article}

\usepackage{lipsum}
\usepackage{graphicx}

\begin{document}

\lipsum[1]

\begin{figure}
\caption{I am visually shifted right!}
\centering
\input{myplot}

% Plot source:
%
% set terminal epslatex color
% set output 'myplot.tex'
% set format '$%g$'
% set ylabel 'A label'
% plot 100000 * sin(x) title '$100000 \sin x$'
%
\end{figure}

\end{document}


The result:

The question is: how does one properly align such a plot, so that the center of the plot matches the center of the page horizontally? (Inserting a matching negative horizontal space manually doesn't count. (-:)

You can set the label with a package. For example: overpic, pstool. –  Marco Daniel May 13 '11 at 13:52
Thanks a lot for this question ! I was going to ask exactly the same :) –  Elenaher Oct 10 '12 at 9:10

You can set the margins of the plot in gnuplot using lmargin at screen 0 and rmargin at screen 1.0, so that the plot takes up the entire canvas. The labels will still be placed correctly:

This is excellent! –  Andrey Vihrov May 13 '11 at 21:36
