A recurrence plot is defined as a plot of the quantity
![]() |
where is the Heaviside step function and
denotes a norm. A recurrence plot is therefore a binary plot. The figure above shows a recurrence plot for the Lorenz attractor with

,
,
,
,
, and
.
Recurrence plots were initially used to graphically display nonstationarity in time series (Eckmann et al. 1987, Gao and Cai 2000), but are also useful for visualizing functions.
A so-called global recurrence plot or unthresholded recurrence plot of a function is a plot of
(or
) in the
-
plane. Recurrence plots for a number of common functions are illustrated above.
