I want to add a cite{} along with each bar value of my pgfplots bars chart. Can I do this?

At the same time, I want to avoid reordering my data.

Currently, my code is similar to the following example:

% Bar charts

% Author: Stefan Kottwitz

% https://www.packtpub.com/hardware-and-creative/latex-cookbook

documentclass[border=10pt]{standalone}

usepackage{pgfplots}

begin{document}

begin{tikzpicture}

  begin{axis}[title  = Contributions per category

                      at LaTeX-Community.org,

  xbar,

  y axis line style = { opacity = 0 },

  axis x line       = none,

  tickwidth         = 0pt,

  enlarge y limits  = 0.2,

  enlarge x limits  = 0.02,

  symbolic y coords = {LaTeX, Tools, Distributions, Editors},

  nodes near coords,

]

addplot coordinates { (57727,LaTeX)         (5672,Tools)

                     (2193,Distributions)  (11106,Editors) };

addplot coordinates { (14320,LaTeX)         (1615,Tools)

                     (560,Distributions)   (3075,Editors)  };

legend{Topics, Posts}

end{axis}

end{tikzpicture}

end{document}

Another method, placing the citation as meta data in the coordinate stream.

If I guess correctly about your second issue, add y dir=reverse.

documentclass{article}

usepackage{pgfplots}



% biblatex not required, just for example

usepackage{biblatex}

addbibresource{biblatex-examples.bib}

begin{document}

begin{tikzpicture}

  begin{axis}[title  = Contributions per category

                      at LaTeX-Community.org,

  xbar,

  y axis line style = { opacity = 0 },

  axis x line       = none,

  tickwidth         = 0pt,

  enlarge y limits  = 0.2,

  enlarge x limits  = 0.02,

  symbolic y coords = {LaTeX, Tools, Distributions, Editors},

  % state that the meta value is given explicitly, and should not be parsed as a number

  point meta=explicit symbolic,

  % save the x-value in DataX, for use later

  visualization depends on=xasDataX,

  % the argument to nodes near coords defines what is actually printed. 

  % first we print the x-value, then the meta information, which 

  % is what is given in the brackets in the coordinate stream

  nodes near coords={pgfmathprintnumber{DataX} pgfplotspointmeta},

  % had to add this to get the alignment right

  nodes near coords align=right,

  % flips the direction of the y-axis

  y dir=reverse

]

addplot coordinates {

  (57727,LaTeX)        [cite{aksin}]

  (5672,Tools)         [cite{angenendt}]

  (2193,Distributions) [cite{bertram}]

  (11106,Editors)      

   };

addplot coordinates {

  (14320,LaTeX)

  (1615,Tools)

  (560,Distributions)

  (3075,Editors)

   };

legend{Topics, Posts}

printbibliography

Here is a way to add citations. The second point of your question I do not understand.

documentclass{article}

usepackage{pgfplots}

pgfplotsset{compat=1.16,    

name nodes near coords/.style={ % https://tex.stackexchange.com/a/75811/121799

        every node near coord/.append style={

            name=#1-coordindex,

            alias=#1-last,

        },

    },

    name nodes near coords/.default=coordnode}

begin{document}

begin{tikzpicture}

  begin{axis}[title  = Contributions per category

                      at LaTeX-Community.org,

  xbar,

  y axis line style = { opacity = 0 },

  axis x line       = none,

  tickwidth         = 0pt,

  enlarge y limits  = 0.2,

  enlarge x limits  = 0.02,

  symbolic y coords = {LaTeX, Tools, Distributions, Editors},

  nodes near coords,name nodes near coords=bn

]

addplot coordinates { (57727,LaTeX)         (5672,Tools)

                     (2193,Distributions)  (11106,Editors) };

addplot coordinates { (14320,LaTeX)         (1615,Tools)

                     (560,Distributions)   (3075,Editors)  };

legend{Topics, Posts}

end{axis}

node[anchor=west] at (bn-1.east){see cite{Witten:2017hdv}};

end{tikzpicture}
