[pstricks] labels and loglines

[Denis Vergès]

Hello,
With this code :
\psset{yunit=10cm}
\begin{pspicture}(13,1)
\psaxes 
[axesstyle=frame,logLines=y,ylogBase=10,subticks=10,xsubticks=2,xticksiz 
e=0 1,xsubticksize=1,Dx=5,yticklinestyle=dashed](13,10)
\uput[d](12.5,0){$t$ (heures)}
\uput[l](-0.5,10){$q$ (mg)}
\end{pspicture}

I want to put on the y-axis the labels 2,3,4,..., 9.
How can I do ?
Thanks for your help.
