Figure 4From: Dynamical density delay maps: simple, new method for visualising the behaviour of complex systems Selected snapshots from the D3-Map animation derived from the analysis of the interbeat interval time series shown in the top panel of Figure 1. Each snapshot comprises: a 500 sec interbeat interval time series segment (bottom), its colourised 2D contour map (middle) and colourised 3D surface Poincaré map (top).
