[pstricks] suppress labels with \psaxes option ``axesstyle=polar''?

[Hensh, Richard]

Is it possible to modify (or suppress) the labels generated using the polar axesstyle option? The following code does not suppress the labels.

\psaxes[axesstyle=polar,subticklinestyle=dashed,subticks=2,labels=none](3,3) 

thanks
