# Pgfplot figure off-center

I create a tikzpicture in standalone mode (see code below). Then import the resultant .pdf file into my document via \includegraphics (see pic). However the axis labels are cut off and part of the ytick when using [trim axis left, trim axis right]. If I don't use that command it looks fine but is not centered any more. Any thoughts?

PS this is a duplicate but perhaps more concise of this Pgfplot figure off-center because of axis label

\documentclass[tikz,border=12pt]{standalone}
\usepackage{pgfplots}
\usetikzlibrary{plotmarks}
\begin{document}
\definecolor{mycolor1}{rgb}{0.0416666666666667,0,0}

One thing you could do is (manually) increase the border around the graph. The standalone package allows the left and right borders to be set independently of the top and bottom borders. So, if you change

\documentclass[tikz,border=12pt]{standalone}


to

\documentclass[tikz,border={38pt 12pt}]{standalone}


then your y-axis labels will not be cropped, and your graph will remain centred. The only downside is that this is a bit of a dirty hack!

Very nice! thank you. By the way how did you decide on 38pt? ie how did you know teh graph would still be centered? –  HCAI May 3 '13 at 12:09
You're welcome. You had already centred the graph using your [trim axis left, trim axis right]. My border={38pt 12pt} then adds a 38pt border to the left and right equally, which keeps the graph centred, whichever numbers are used. I just came up with 38pt by trial and error. –  John Wickerson May 3 '13 at 12:13
Ah I see! So is the 38pt graph size dependent? –  HCAI May 3 '13 at 12:32
Yes, it depends on the size of the labels and ticks to the left of your axis. In other words, my solution is not particularly elegant. –  John Wickerson May 3 '13 at 16:39
Yes. Put xtick pos=left and ytick pos=left in your axis options. (The default is both.) –  John Wickerson May 4 '13 at 7:00
