# Another “Dimension too large” question: PSTricks plot

I'm currently using Pstricks to plot a datafile into a basic x-y figure. My actual code is:

\psset{xunit=.07cm,yunit=0.00025cm}
\begin{pspicture}(1915,10000)(2015,30500)
\psaxes[Dx=10,Dy=15000,Ox=1915,Oy=13000,ticksize=-3pt,labelFontSize=\scriptstyle]{->}(1915,13000)(2015,28000)[,-90][X (s.),0]
\fileplot[plotstyle=dots, dotscale=0.8]{Figures/figure20-B1.prn}
\end{pspicture}


Part of my data is:

1922,27169
1923,23561
1925,21835
1926,20167
1928,20003
1942,19910
1944,19123
1952,18585
1953,18115
1961,17110
1965,16503
1975,15629
1976,14947
1979,14758
1983,14288
1986,13735
1998,13137


It works just fine, except I do not have any label in the Y axis (because of the Dy=15000). The main thing is that I could actually have ticks on the y axis by reducing Dy (say Dy=2000) and increasing yunit in psset. However, I tried in and it do not work at all.

I tried \pstScalePoints, local y-axis scaling (yunit=xxx in the fileplot parameters, although I'm not sure yunit is part of the authorized variables of fileplot parameter) and it didn't change the thing.

I would greatly appreciate some help on this redundant topic (I already browsed associated Dimension too large topics and tried some alternative but gosh, I must be wrong somewhere...).

Usually, we don't put a greeting or a "thank you" in our posts.

I created a minimal working example (MWE) of your code snippet and it works fine:

\begin{filecontents}{figure20-B1.prn}

1923,23561
1925,21835
1926,20167
1928,20003
1942,19910
1944,19123
1952,18585
1953,18115
