Not really, as there is not a hazard function. The KM _estimate_ of the
survivor function is a step function: only (a.e) differentiable survival
distributions have hazard functions you could plot.
If you can be more precise we may be able to help: there are ways to
estimate hazard functions from data (see Chapter 12 of the V&R2 Statistical
Complements), and you can do cumulative hazard plots.
