Graphics, Figures & Tables ⇒ pgfplots graph labels (year/month)

[m1l05z]

Hi,
I am trying to use a graph in pgfplots of this example: http://tex.stackexchange.com/questions/ ... n-pgfplots @Jake's answer, I added my data but my graph looks strange:


Here is my graph's code:

Code: Select all

\usepackage{pgfplots}
\usepgfplotslibrary{dateplot} 
\usetikzlibrary{calc}
\makeatletter
\long\def\ifnodedefined#1#2#3{%
  \@ifundefined{pgf@sh@ns@#1}{#3}{#2}%
}
\makeatother
    \begin{tikzpicture}
    \begin{axis}[
    date coordinates in=x,
    xtick=data,
    tick pos=left,
    yticklabel style={append after command={(\tikzlastnode.east) edge +(0.15cm,0)}},
    major tick length=0pt,
    extra x ticks={2013-10-01,2014-06-01, 2015-07-01},
    extra x tick style={
        yshift=-3.5ex,
        xticklabel=\year,
        xticklabel style={name={}},
        every x tick label/.style={}
    },
    xticklabel style={
        anchor=near xticklabel,
        alias=tick\ticknum,
        name=\ifnodedefined{start\year} % Have we already started this year?
            {end\year}  % Then this could be the last month
            {start\year}, % Otherwise, start the year
        append after command=
            \pgfextra{\pgfmathtruncatemacro\lastyear{\year-1}}
            \ifnodedefined{end\lastyear}
            {
                {\ifnum\month=1 ({$(end\lastyear.south west)!0.7!(start\year.south east)$}|-{rel axis cs:0,0}) edge ++(0,-7ex)
                \fi}
            }
            {}
            \ifnum\ticknum>0
                    \ifnum\month>1
                        \pgfextra{\pgfmathtruncatemacro\prevticknum{\ticknum-1}}
            ($(tick\prevticknum.north east)!0.5!(tick\ticknum.north west)$) edge ++({0,-3ex})
                    \fi
            \fi
    },
    after end axis/.code={
        \draw (rel axis cs:0,0) -- ++(0,-7ex)
                (rel axis cs:1,0) -- ++(0,-7ex);
    },
    xticklabel=\month,
    date ZERO=2013-08-01,% <- improves precision!
    ]
    \addplot coordinates {
    (2013-08-01, 215329)
    (2013-10-01, 225632)
    (2013-12-01, 229746)
    (2014-01-01, 231838)
    (2014-03-01, 233103)
    (2014-04-01, 236439)
    (2014-06-01, 240507)
    (2014-07-01, 259075)
    (2014-09-01, 269991)
    (2014-11-01, 268667)
    (2014-12-01, 267881)
    (2015-02-01, 276134)
    (2015-03-01, 294944)
    (2015-05-01, 297439)
    (2015-07-01, 297291)
    (2015-08-01, 286560)
    (2015-09-01, 280206)
    };
    \end{axis}
    \end{tikzpicture}

I will be grateful of any sugestions
