Hi, > This plots a nice implicit plot for various values of e1. What I wish to do is to attach a > "sense" to the contours (an arrow that describes the direction of the orbit). that is nonsense, because the direction of the orbit depend on your initial condition. Start with a positive x'[t] and a negative x[t] and your orbit is counter clock wise and with a negative x'[t] your orbit is clock wise.
