[pstricks] Dimension too large?

[David Arnold]

All,

This:

\documentclass{article}
\usepackage{amsmath}
\usepackage{pst-bar}
\usepackage{pstricks-add}
\usepackage{filecontents}
\begin{document}

\begin{filecontents*}{HumboldtPopulation.csv}
7322,26672,78142,16194
\end{filecontents*}

\begin{center}
\psset{xunit=0.4in,yunit=0.000025in}
\begin{pspicture}(-2,0)(5,80000)
\psframe[fillstyle=solid,fillcolor=black!10,linestyle=solid](0,0) 
(5,80000)
\psaxes[yticksize=0 5,ticks=y,labels=y,Dy=10000](0,0)(0,0)(5,80000)
\readpsbardata[header=false]{\data}{HumboldtPopulation.csv}
\psbarchart[barstyle=blue]{\data}
\rput{90}(-1.25,40000){Humboldt Population}
\end{pspicture}
\end{center}

\end{document}

Produces this error:

! Dimension too large.
<to be read again>
                    =
l.17 \readpsbardata
                    [header=false]{\data}{HumboldtPopulation.csv}
?


Anyone know what this means? Workaround?

David.
