## Main Question or Discussion Point

Hi

I have a 2d trajectory of a center of mass which I have saved in an array such that r=[[x(t_1),y(t_1)],[x(t_2),y(t_2)],....,[x(t_n),y(t_n)]] where x is x coordinate of the position and y is the y-coordinate of the position.

I have tried this:

xx = [t[0] for t in r]

xy = [t[1] for t in r]

plt.plot(xx,xy)

plt.show()

It produced a plot, but I cannot make it look right. It's supposed to be rotating, but no matter how I change the initial conditions (it's a PDE), the resulting plot doesn't look like a rotation.

How should I go about to plotting this trajectory?
