[pstricks] Axes and huge numbers

[Martin Chicoine]

auto-pst-pdf does not work because of psgraph. As a workaround you can use
the following preamble but I think there are problems.

 

\documentclass{article}

 

\usepackage{auto-pst-pdf}

\usepackage{pstricks-add}

 

\usepackage{ifpdf}

\ifpdf

  \let\psgraph=\postscript

  \let\endpsgraph=\endpostscript

\else

  \PreviewEnvironment{psgraph}

\fi

 

\begin{document}

Thanks a lot Martin, looks great. However, for some reason the auto-pst-pdf
package does not work, which is really annoying me. Anyway, it's good to
know that solution, thanks! :)

With pstricks-add you can divide everything by 1000 and use xlabelFactor and
ylabelFactor. The only problem is that you have to use showorigin=false,
otherwise you get "0000" at the origin. Maybe Herbert has a fix for that?

\documentclass{article}

\usepackage{pstricks-add}

\begin{document}

\begin{psgraph}[arrows=->,Dx=250,Dy=50,xlabelFactor={000},ylabelFactor={000}
,
 showorigin=false](0,0)(1500,160){11.2cm}{6.4cm}
% Functions
\psplot[showpoints=true,plotpoints=15]{0}{1500}{0.08615 x mul 18 add}
\psplot[showpoints=true,dotstyle=square*,plotpoints=15]{0}{1500}{0.05468 x
mul 42 add}
% Captions
\rput[l](1000,70){\psline(0,2)(100,2)\psdot(50,2)\qquad\quad graph one}
\rput[l](1000,50){\psline(0,2)(100,2)\psdot[dotstyle=square*](50,2)\qquad\qu
ad graph two}
\end{psgraph}

\vspace{1cm}

\psset{unit=.00008mm,xunit=.00008mm,yunit=.0004mm}

\begin{pspicture}(0,0)(1500000,160000)
% Axes
\psaxes[Dx=250000,Dy=50000,labels=none]{->}(0,0)(1500000,160000)
% Functions
\psplot[showpoints=true,plotpoints=15]{0}{1500000}{0.08615 x mul 18000 add}
\psplot[showpoints=true,dotstyle=square*,plotpoints=15]{0}{1500000}{0.05468
x mul 42000 add}
% Captions
\rput[l](1000000,70000){\psline(0,2000)(100000,2000)\psdot(50000,2000)\qquad
\quad graph one}
\rput[l](1000000,50000){\psline(0,2000)(100000,2000)\psdot[dotstyle=square*]
(50000,2000)\qquad\quad graph two}
\end{pspicture}
