Nodes won't position as they should in pgfplots

Question

When I use the example of the pgfplots manual it looks different from what is shown in the manual:

\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[title=Snap to nearest for scatter plots]
\addplot+[only marks]
coordinates {(0,0) (1,1) (2,2) (3,3)}
node[pos=0,pin=0:0] {}
node[pos=0.1, pin=90 :0.1 ] {}
node[pos=0.2, pin=200:0.2 ] {}
node[pos=0.3, pin=135:0.3 ] {}
node[pos=0.4, pin=0
:0.4 ] {}
node[pos=0.5, pin=60 :0.5 ] {}
node[pos=0.75,pin=180:0.75] {}
node[pos=1,pin=90 :1] {};
\end{axis}
\end{tikzpicture}
\end{document}

This is the result:

This part pos=0.75 etc. is obviously not working. What am I doing wrong?

I use TeXnicCenter 1.0 RC1 with MiKTeX 2.9.

As cmhughes suggested, you need a more recent version of pgfplots: support for pos=0.75 and its variants has been added in version 1.5.1 (can be obtained via CTAN, TeX package managers or http://pgfplots.sourceforge.net/).
