pst-plot graph offset on page when graph has non-zero origin

Question

This question relates to the use of pst-plot with datasets that have x axis values starting from a positive number for example x = 0.5 -> 0.8.

In the case below, on two separate computers both running Texlive (pdfTeX 3.1415926-2.5-1.40.14 (TeX Live 2013/Debian)), the dvi output is shifted to the right by about the width of the graph.

If DVIPS -E is used to extract the picture to an EPS file this too has extra white space on the left of the graph.

It's quite likely that this is a problem in which I don't understand the options I’m setting properly and the behaviour is expected.

Some example code:

\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage{pstricks,pst-eps,graphicx,pst-grad,amsmath,pst-all}
\pagestyle{empty}
\thispagestyle{empty}

\begin{document}
\readdata{\OPA}{transferCharacteristics.txt}
\readdata{\OPB}{transferCharacteristics2.txt}
\readdata{\OPC}{transferCharacteristics3.txt}
\readdata{\OPD}{transferCharacteristics4.txt}

\pslegend[lt]{\black\rule[1ex]{2em}{1pt} & 10~V\\
\red\rule[1ex]{2em}{1pt} & 30~V\\
\green\rule[1ex]{2em}{1pt} & 50~V\\
\blue\rule[1ex]{2em}{1pt} & 70~V}

\psset{llx=0cm,lly=0cm, xAxisLabel={$V_{\mathrm{BE}}$ [V]}, xAxisLabelPos={c,-0.3in}, yAxisLabel={$I_\mathrm{C}$ [A]}, yAxisLabelPos={-0.5in,c},ury=0.0cm,urx=0cm}

\begin{psgraph}[axesstyle=axes,xticksize=0 0.20,yticksize=0 0.30,subticks=0, Dx=0.1, Dy=0.02, Oy=0, Ox=0.5](0.5,0)(0.5,0)(0.801,0.201){6cm}{5cm}
\pstScalePoints(1,1){}{}

\listplot[linecolor=black,linewidth=1pt]{\OPA}
\listplot[linecolor=red,linewidth=1pt]{\OPB}
\listplot[linecolor=green,linewidth=1pt]{\OPC} 
\listplot[linecolor=blue,linewidth=1pt]{\OPD}

\end{psgraph}
\end{document}

where transferCharacteristics.txt etc. are in the form:

5.500000000000000e-001,2.631940e-005
5.512678809428449e-001,2.764127e-005
5.525386846531173e-001,2.903280e-005
5.538124178684922e-001,3.049784e-005
5.550890873421763e-001,3.204043e-005
5.563686998429440e-001,3.366487e-005
5.576512621551735e-001,3.537569e-005

and are each 153 lines in length.

For a single image use documentclass standalone:

\documentclass[pstricks,border=2mm]{standalone}
\usepackage[utf8]{inputenc}
\usepackage{pst-plot}

\begin{document}
    \readdata{\OPA}{transferCharacteristics.txt}
    \readdata{\OPB}{transferCharacteristics2.txt}
    \readdata{\OPC}{transferCharacteristics3.txt}
    \readdata{\OPD}{transferCharacteristics4.txt}

    \pslegend[lt]{\black\rule[1ex]{2em}{1pt} & 10~V\\
    \red\rule[1ex]{2em}{1pt} & 30~V\\
    \green\rule[1ex]{2em}{1pt} & 50~V\\
    \blue\rule[1ex]{2em}{1pt} & 70~V}
    \psset{llx=-1.5cm,lly=-1cm, xAxisLabel={$V_{\mathrm{BE}}$ [V]}, xAxisLabelPos={c,-0.3in}, yAxisLabel={$I_\mathrm{C}$ [A]}, yAxisLabelPos={-0.5in,c},ury=0.0cm,urx=0cm}
    \begin{psgraph}[axesstyle=axes,xticksize=0 0.20,yticksize=0 0.30,
      subticks=0, Dx=0.1, Dy=0.02, Oy=0, Ox=0.5](0.5,0)(0.5,0)(0.801,0.201){6cm}{5cm}
    \listplot[linecolor=black,linewidth=1pt]{\OPA}
    \listplot[linecolor=red,linewidth=1pt]{\OPB}
    \listplot[linecolor=green,linewidth=1pt]{\OPC} 
    \listplot[linecolor=blue,linewidth=1pt]{\OPD}
    \end{psgraph}

\end{document}

Or you can use preview package plus article class instead of standalone class to get the same (based on our bare eyes) result.

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{pst-plot}
\usepackage[active,tightpage]{preview}
\PreviewEnvironment{pspicture}
\PreviewBorder=12pt\relax % if you need 12pt border around the output


\begin{document}
    \readdata{\OPA}{transferCharacteristics.txt}
    \readdata{\OPB}{transferCharacteristics2.txt}
    \readdata{\OPC}{transferCharacteristics3.txt}
    \readdata{\OPD}{transferCharacteristics4.txt}

    \pslegend[lt]{\black\rule[1ex]{2em}{1pt} & 10~V\\
    \red\rule[1ex]{2em}{1pt} & 30~V\\
    \green\rule[1ex]{2em}{1pt} & 50~V\\
    \blue\rule[1ex]{2em}{1pt} & 70~V}
    \psset{llx=-1.5cm,lly=-1cm, xAxisLabel={$V_{\mathrm{BE}}$ [V]}, xAxisLabelPos={c,-0.3in}, yAxisLabel={$I_\mathrm{C}$ [A]}, yAxisLabelPos={-0.5in,c},ury=0.0cm,urx=0cm}
    \begin{psgraph}[axesstyle=axes,xticksize=0 0.20,yticksize=0 0.30,
      subticks=0, Dx=0.1, Dy=0.02, Oy=0, Ox=0.5](0.5,0)(0.5,0)(0.801,0.201){6cm}{5cm}
    \listplot[linecolor=black,linewidth=1pt]{\OPA}
    \listplot[linecolor=red,linewidth=1pt]{\OPB}
    \listplot[linecolor=green,linewidth=1pt]{\OPC} 
    \listplot[linecolor=blue,linewidth=1pt]{\OPD}
    \end{psgraph}
\end{document}
