Sorry don't think it is possible. All I want to do is decrease the horizontal separation between two different plots. — LionsFan, Jan 26 '18 at 05:24
The answer will depend on which style files you are loading and so on. Without that information, I can only guess that you may want to remove the line x=7cm,. — , Jan 26 '18 at 05:26
I included the classes I am including in my main file and I added the image as well. Hope that helps? — LionsFan, Jan 26 '18 at 05:34
No, it doesn't compile because there is no \documentclass, nor \begin{document} nor \end{document}. But I guess you really just need to play with x=7cm,, e.g. by replacing it by x=3.5cm,. — , Jan 26 '18 at 05:53
Thank you. But when I do that, it shrinks the size of the plot and the outer bars get cutoff with the border. — LionsFan, Jan 26 '18 at 06:04
comment out the bar width=17pt that forces the plots to get out of the "supposed" area that they would use (or reduse it to half too) — koleygr, Jan 26 '18 at 06:12

For me the key to a good solution is to switch from absolute width (in pt) to relative width using the axis coordinate system. Doing this has the advantage that when you once have fixed the bar widths and "distance of the bars to the axis" (using enlarge x limits) you can scale your plot using width only.

For details please have a look at the comments in the code.

I have removed my answer because yours is much better. Maybe you want remove the link in the first sentence. — esdd, Jan 26 '18 at 08:18
@esdd, for me your answer was totally valid and fine. But thank you for the credits. — Stefan Pinnow, Jan 26 '18 at 20:27

i would draw this plots on the following way:

\documentclass[border=5pt]{standalone}
\usepackage{pgfplots, pgfplotstable}
\pgfplotsset{compat=1.15}
\pgfplotstableread[row sep=\\,col sep=&]{
    interval & carT  & carD   & carC    & carG    \\
    10 Hz    & 62680 & 125130 & 10000   & 100000  \\
    OSC      & 62680 & 125130 & 100000  & 100000  \\
    Adaptive & 62680 & 125130 & 1000000 & 1000000 \\
}\mydata
\begin{document}
\begin{tikzpicture}
\begin{axis}[
     width=1\textwidth,
    height=.5\textwidth,
    ymin=0,
    ymax=1 150 000,
    yticklabel style={/pgf/number format/fixed},
    ytick distance=200 000,
    axis y discontinuity=crunch,
    ylabel={Number of Packets Sent},
    xtick=data,
    xticklabels from table={\mydata}{interval},
    bar width=0.2,
    ybar=2pt,
    enlarge x limits={abs=0.55},
    nodes near coords,
    nodes near coords style={font=\tiny},
    /pgf/number format/.cd,use comma,sci,
    /pgf/number format/sci generic={mantissa sep={\!\!\cdot\!\!},
                                    exponent={10^{####1}}
                                    },
    legend pos=north west,
    legend style={legend columns=-1},
]
    \addplot table [x expr=\coordindex,y=carT]{\mydata};
    \addplot table [x expr=\coordindex,y=carD]{\mydata};
    \addplot table [x expr=\coordindex,y=carC]{\mydata};
    \addplot table [x expr=\coordindex,y=carG]{\mydata};

    \legend{Six Lanes, 12 Lanes, E.C. Row, i75}
