[pstricks] Dimension too large?

[Michael Sharpe]

David,

PSTricks stores coordinates in dimension registers, which have a  
maximum possible value of about 19ft. If any coordinate in your  
picture would be that distance from the true origin, you will get that  
error. (It is very common.) The fix is to use \psbarscale to rescale  
the y values.

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

\psset{xunit=0.4in,yunit=0.0025in}
\begin{pspicture}(-2,0)(5,800)
\psframe[fillstyle=solid,fillcolor=black!10,linestyle=solid](0,0)(5,800)
\psaxes[yticksize=0 5,ticks=y,labels=y,Dy=10000](0,0)(0,0)(5,800)
\readpsbardata[header=false]{\data}{HumboldtPopulation.csv}
\psbarscale(.01){}
\psbarchart[barstyle=blue]{\data}
\rput{90}(-1.25,400){Humboldt Population}
\end{pspicture}
