When using pst-plot commands and the pstricks backend it is possble to generate an unwanted whitespace next to the picture.  See for example the files at http://www.iceamplifiers.co.uk/randomstuff/pstplotwhitespace/ of which the .tex file is a composite of some code that shows the potential bug, wrappered in the standard backed file pst_latex.ckt file. When this same file is compiled from the command line using the "standalone" class as per http://tex.stackexchange.com/questions/204800/pst-plot-graph-offset-on-page-when-graph-has-non-zero-origin/ the whitespace is removed. Yet, when I modify the Cirkuit backend file pst_latex.ckt to produce:

\documentclass[border=2mm]{standalone}
\usepackage{pst-plot,pst-all,graphicx}
\begin{document}

% MWE picture code starts here    
    \readdata{\OPA}{transferCharacteristics.txt}
    \readdata{\OPB}{transferCharacteristics2.txt}

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

The whitespace is back. I wonder if something inside Cirkuit is responsible?

Reproducible: Always

Steps to Reproduce:
0. pull my example files from http://www.iceamplifiers.co.uk/randomstuff/pstplotwhitespace/
1. fire up cirkuit (Version 0.4.3, Using KDE Development Platform 4.13.3)
2. call up a new PSTricks drawing file
3. save the empty file to the same directory that the files in step 0 were saved to.
4. paste the following into the code window

 \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}
5. ctrl + 1 to regenerate
6. observe how the graph isn't central
7. ctrl + 2  to observe the problem in Okular or similar.
8. hyperventilate.

Actual Results:  
there is some whitespace to the left of the image which should not be there.

Expected Results:  
No whitespace to the left of the image (as per the details)
