在坐标附近的节点处勾勒出数字

Question

是否可以用黑色勾勒出白色数字的轮廓？白色数字位于蓝色列内

\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.9}

\begin{document}

\begin{tikzpicture}
\begin{axis} [ybar, 
width=10cm, 
height=6cm,
ymin=0,
title=Firsidet og sekssidet terninger efter 50. kast,
xlabel=Øjnenes sum,
ylabel=Hyppighed,
%bar width=5pt,
xtick={2,...,10},
nodes near coords,
nodes near coords style={font=\boldmath\tiny,color=white,rotate=90,anchor=east},
every tick label/.append style={font=\footnotesize},
label style={font=\footnotesize},
]

\addplot[color=black,fill=blue!70] 
table[x=sum,y=hyp]{
sum hyp
2   1
3   6
4   5
5   7
