[Tex/LaTex] Spacing in pgfplots bar plot

pgfplotsspacingtikz-pgf

I've been trying to plot an xbar graph using pgfplots within a tikzpicture. I want to be able to only show the yaxis on the left and the x axis on the bottom. When I set axis y line=left and axis x line=bottom though, I get arrows on the axis. Is it possible to remove them? Also, I can't seem to control the spacing of the bar plots, is that possible? I'd like them to be much closer together then they are currently. Here's my attempt so far:

\begin{tikzpicture}
  \begin{axis}[
    xbar,
    symbolic y coords={4 Sep 11,4 Oct 11,4 Nov 11},
    width=0.4\textwidth,
    height=0.15\textheight,
    nodes near coords={\$\pgfmathprintnumber\pgfplotspointmeta},
    nodes near coords align={horizontal},
    xtick=\empty,
    axis x line=bottom,
    axis y line=left,
    xmin=0,
    bar width=12pt,
    enlarge limits=0.2,
  ]
  \addplot[fill=blue]
    coordinates {(121.28,4 Nov 11) (100.00,4 Oct 11) (50.00,4 Sep 11)};
  \end{axis}
\end{tikzpicture}

The output of which is:

Things I have tried: enlarge limits (If I enable it, the plot looks a bit nicer), xbar interval and shrinking the height of the plot to no avail. I'm a little stumped at the moment.

Use the starred version of these options. Regarding the distance between the bars you should increase the height of the plot.

\documentclass{minimal}
\usepackage{pgfplots}

\begin{document}
  \begin{tikzpicture}
    \begin{axis}[%
      xbar,
      symbolic y coords={4 Sep 11,4 Oct 11,4 Nov 11},
      width=0.4\textwidth,
      height=0.25\textheight,
      nodes near coords={\$\pgfmathprintnumber\pgfplotspointmeta},
      nodes near coords align={horizontal},
      xtick=\empty,
      axis x line*=bottom,
      axis y line*=left,
      xmin=0,
      bar width=12pt,
      enlargelimits=0.2,
    ]
      \addplot[fill=blue] coordinates {(121.28,4 Nov 11) (100.00,4 Oct 11) (50.00,4 Sep 11)};
    \end{axis}
  \end{tikzpicture}  
\end{document}

[Tex/LaTex] Asymmetric “enlarge x limits” in pgfplots

PGFPlots uses the same value for both upper and lower limit in enlarge * limits; the use-case of different values is unsupported (sorry). You may need to consider a different solution.

[Tex/LaTex] How to scale y axis and position labels in xbar plot

If you supply xbar to the axis, each \addplot command will have a different vertical offset. This allows you to have two bars with the same nominal y coordinate that don't overlap. For example if you have
```
\addplot coordinates {(1,1) (3,2) (1,3)};
\addplot coordinates {(1,1) (2,2) (3,3)};
```
you'll get

Note that none of the bars are actually at the specified vertical positions (1,2,3), but they're either above or below. This is a really useful feature in most cases. In your application, however, each series (i.e. each \addplot command) only has one data point, so the offset is undesirable, especially since the axis limits aren't automatically adjusted. To switch off the offset, just add bar shift=0pt to your axis options and remove the enlarge y limits:
nodes near coordinates align only works with numerical metadata, because it uses the sign of the value to decide whether to put the label on the left or the right of the bar. To place symbolic labels to the right of the bars, use every node near coord/.append style={anchor=west}. Note that the axis limits won't automatically be adjusted to accommodate the labels, so you might have to set something like enlarge x limits={upper, value=0.2}.
