additional arguments to plot |
The displacement from a particular time point (t_a
) to every other point along the trajectory is calculated and this is then plotted over a defined window [t_1
, t_2
]. A line representing the radius is also drawn to see when the trajectory enters or leaves the circle centred at the point (t_a
). This plot can be used to see how far away the animal moves after leaving a particular circle.
