[pstricks] fileplot problem

[Aydin Ustun]

I am trying to plot a time series between 1980-2005 years from a 
external file. But, the output does not appear in the axes-frame.

Please, can anyone help me?
Thanks


\documentclass[12pt,a4paper]{article}
\usepackage{pst-plot}
\usepackage{pstricks-add}
\begin{document}
\psset{xunit=5mm,yunit=0.003mm}
\begin{pspicture}(25,25000)
\psaxes[axesstyle=frame,Dx=5,%
        Dy=5000](25,25000)%
\fileplot[linewidth=1pt, linecolor=blue]{data2.dat}
\end{pspicture}
\end{document}
