    Welcome! Please provide an MWE. – user121799 Jan 26 '18 at 5:16
  • 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 5:24
  • 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,. – user121799 Jan 26 '18 at 5:26
  • 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 5:34
  • @marmot I believe that should give enough MWE, doesn't it? – LionsFan Jan 26 '18 at 5:51

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 8:18
  • @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:

enter image description here

\documentclass[border=5pt]{standalone}
\usepackage{pgfplots, pgfplotstable}
\pgfplotsset{compat=1.15}
\pgfplotstableread[row sep=\\,col sep=&]{

    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},

    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};
