Please provide _full working_ examples. How should one know
that you are using package arrajob or arrayjobx??
However, you can do it with the default PSTricks macros:

\documentclass{article}
\usepackage{pst-func}

\begin{document}
\newcounter{iA} \setcounter{iA}{1}
\begin{psgraph}[Dy=0.2]{->}(0,0)(-5.5,-0.1)(5.5,0.6){10cm}{10cm}
\pgfforeach \kp/\kc in {1/black,2/orange,5/cyan,10/red}{%
   \rput(!2.2 0.2 0.05 \theiA\space mul add){k=\kp}
   \psset{linecolor=\kc,linewidth=1.5pt}%
   \psline(!3.5  0.2 0.05 \theiA\space mul add)(!4.5  0.2 0.05
\theiA\space mul add)
   \psTDist[linecolor=\kc,nue=\kp]{-5}{5}
   \stepcounter{iA}%
}
\end{psgraph}

\end{document}

The macros of arrayjob are not expandable.
