Extracting patterns from the spatiotemporal movement of objects
You could take the difference between coordinates occuring consecutively. This gives your displacement vector. Then create two plots one indicating the magnitude of displacement( $((\delta x_{t})^{2}+(\delta y_{t})^{2})^{1/2}$) vs time and another plot of the direction indicated by the angle of the vector from the x axis; given by $\theta_{t} = tan^{-1}(\delta y/\delta x)$.
Hence you could visualize the magnitude and direction with respect to time.
