# Differing left and right axis labels in psplot

This question is related to psgraph with y-axis on left and right of graph and axis labels but can stand alone, as it is really about loops and variables.

I'm really sad that I have to ask this question, I am clearly incompetent.

In the following code can I replace the set of 13 consecutive \rput commands (near to the bottom) with \multido{...}?

The objective is to have a different scale on the right axis to that on the left. I have managed this, but the code is so inelegant there must be a proper way. It seems like you ought to be able to \def\anumber{lowest y axis value string } and then do some simple arithmetic on it inside a \multido to place the desired text in the desired locations.

\begin{pspicture}(1.2,1)

\psset{llx=-1cm,lly=-1cm}

\psset{xAxisLabel={Time [ms]}, xAxisLabelPos={c,-0.3in}, yAxisLabel={Voltage [V]}, yAxisLabelPos={-0.3in,c}}

\begin{psgraph}[axesstyle=axes, xticksize=0 12, yticksize=0 5, subticks=0, Dx=0.5, Oy=-6](0,-6)(5,6){7cm}{5cm}

\pstScalePoints(1e3,1e0){}{}

\listplot[linecolor=blue,linewidth=2pt]{\vin}
\listplot[linecolor=black,linewidth=2pt]{\vout}

\rput[r](5.58,-6){$-1.2$}
\rput[r](5.58,-5){$-1.0$}
\rput[r](5.58,-4){$-0.8$}
\rput[r](5.58,-3){$-0.6$}
\rput[r](5.58,-2){$-0.4$}
\rput[r](5.58,-1){$0.2$}
\rput[r](5.58,-0){$0.0$}
\rput[r](5.58,1){$0.2$}
\rput[r](5.58,2){$0.4$}
\rput[r](5.58,3){$0.6$}
\rput[r](5.58,4){$0.8$}
\rput[r](5.58,5){$1.0$}
\rput[r](5.58,6){$1.2$}

\rput{90}(5.85,0){Current[$\mu$A]}

\pstScalePoints(1e3,5e3){}{}
\listplot[linecolor=red,linewidth=2pt]{\idone}
\listplot[linecolor=green,linewidth=2pt]{\idtwo}

\end{psgraph}

\end{pspicture}

no need for \multido. Use a second axis:

\documentclass{scrartcl}
\usepackage{pst-plot}
\begin{document}

\psset{llx=-1cm,lly=-1cm,
xAxisLabel={Time [ms]}, xAxisLabelPos={c,-0.3in},
yAxisLabel={Voltage [V]}, yAxisLabelPos={-0.3in,c}}

\begin{psgraph}[axesstyle=axes,xticksize=0 12,yticksize=0 5,subticks=0,Dx=0.5,Oy=-6](0,-6)(5,6){7cm}{5cm}
\pstScalePoints(1e3,1e0){}{}
\psaxes[xAxis=false,Dy=0.2,dy=1,ticks=none,axesstyle=none](5.9,0)(5.9,-6)(5.9,6)
\listplot[linecolor=blue,linewidth=2pt]{\vin}
\listplot[linecolor=black,linewidth=2pt]{\vout}
\rput{90}(5.9,0){Current[$\mu$A]}

\pstScalePoints(1e3,5e3){}{}
\listplot[linecolor=red,linewidth=2pt]{\idone}
\listplot[linecolor=green,linewidth=2pt]{\idtwo}

\end{psgraph}

\end{document}
