 ## @deftypefn {Function File} plot (@var{dat})
-## Plot iddata sets.
+## Plot signals of iddata identification datasets on the screen.
+## The signals are plotted experiment-wise, either in time- or
+## frequency-domain.  For multi-experiment datasets,
+## press any key to switch to the next experiment.
+## If the plot of a single experiment should be saved by the
+## @command{print} command, use @code{plot(dat(:,:,:,exp))},
+## where @var{exp} denotes the desired experiment.
