Survival Curve - How to Add Number at Risk ?

Hi Folks

How can I add the number at risk along with the x axis on the
Kaplan-Meire survival curve plots?

The statistical packages that I have at my disposal are SPSS and
MedCalc. Both don't seem to have this proviso and I'd be grateful if
someone could prove me wrong or point me in the right direction

Thanks.
