坐标附近的节点 = 值 + 单词

Question

在下面的直方图中，my.dat我希望nodes near coords取数字值，后跟文本。例如：

nodes near coords = {<Label> from \cite{<Cite>}}

我使用的代码是：

\begin{filecontents}{my.dat}
y   x   Label   Cite
1   0.9 AK  Hong
2   1.4 RE  Teng
3   2.1 QP  Smith
4   0.7 LR  Croqa
\end{filecontents}

\begin{tikzpicture}
\begin{axis}[
    xbar,
    width=8cm, height=5cm,
    axis lines*=left,
    xlabel={},
    yticklabels from table={my.dat}{Label},
    ytick=data,
    xticklabel={},
    nodes near coords={'Own Label' from \cite{'Own Cite'}},
    nodes near coords align={horizontal},
    ]
    \addplot table [x=x, y=y] {my.dat};
\end{axis}
\end{tikzpicture}

结果如下：

这就是你想要的吗？我使用了一些来自biblatex-examples.bib以下代码的随机条目。

\documentclass[10pt,a4paper]{article}
\usepackage{booktabs}
\usepackage{textcomp}
\usepackage{siunitx}
\usepackage{pgfplotstable,filecontents}
\pgfplotsset{compat=1.12}
\usepackage{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
\begin{filecontents*}{my.dat}
y   x   Label   Cite
1   0.9 AK      aksin
2   1.4 RE      angenendt
3   2.1 QP      bertram
4   0.7 LR      doody
\end{filecontents*}

\noindent\begin{tikzpicture}
\begin{axis}[
    xbar,
    width=8cm, height=5cm,
    axis lines*=left,
    xlabel={},
    yticklabels from table={my.dat}{Label},
    ytick=data,
    xticklabel={},
    nodes near coords={\thenumber{} from \cite{\thecitation}},
    nodes near coords align={horizontal},
    visualization depends on={value \thisrow{Cite} \as \thecitation},
    visualization depends on={value \thisrow{x} \as \thenumber},
    ]
    \addplot table [x=x, y=y] {my.dat};
\end{axis}
\end{tikzpicture}
