2 questions:

1) How do I move my data labels to the center of my bars?

2) How do I make the labels be purely data labels, and not cumulative values? eg I want the red bar labels to be the value of that bar not red+blue.

\legend{{Handwash only},{Gloves only},{Alcohol rub only}}
\end{axis}
\end{tikzpicture}
\end{document}

EDIT

This code centers the nodes, but makes my data points 10$^3$. How do I get rid of this? 

calculate offset/.code={
        \pgfkeys{/pgf/fpu=true,/pgf/fpu/output format=fixed}
        \pgfmathsetmacro\testmacro{(\pgfplotspointmeta*10^\pgfplots@data@scale@trafo@EXPONENT@y)/2*\pgfplots@y@veclength)}
        \pgfkeys{/pgf/fpu=false}
    },
    every node near coord/.style={
        /pgfplots/calculate offset,
        yshift=-\testmacro
    },
    nodes near coords,
    nodes near coords align=center

My second question isn't answered in the link provided. I'd appreciate any hints about this

    It is answered in the linked question: "You need to provide the meta data explicitly by saying meta=<column name> in your \addplot commands, otherwise PGFplots will use the y value, which is the sum of the individual values.In your case, you'll need to use\addplot ... table ...instead of\addplot coordinatesto be able to use themeta` functionality. I think it's best to open a new question for this, since it's a different problem from the issue of moving the labels to the center of the bars. By only having one question per post, it's much easier for others to find later on – Jake May 23 '13 at 14:39
