The driven damped nonlinear Schrödinger equation is solved numeri­cally and different attractors - periodic and chaotic ones - are obtained for different ranges of the forcing field amplitude. It is shown that these attrac­tors are in both cases spatially nonuniform in time. Spatial inhomogeneity of the chaotic attractor is investigated by the estimation of the correlation dimension at different space points.
