I was referring to [the question I posted earlier in Mathematics forum][1], but then I came to see [this example on Wikipedia][2]. How did they plot the system in phase space?

The closet relevant topic I have done is the Lorenz Equation, where I used NDSolve and then ParametricPlot3D evaluated at the fix points.
