Phase diagram of a chaotic system (Rungler)

Hello,

I'm trying to visualize the phase space of a two oscillator chaotic system. i tried following the advise in this article ( https://geoffboeing.com/2015/04/visualizing-chaos-and-randomness/) which also seems consistent with the visualization of the Lorenz attractor example found in gen~.chaos.maxpat.

My current understanding is that i should map the chaotic variable at point t on the x axis and at point t+1 on the y. I tried doing this by adding a history object to my code, thus mapping t-1 on the x and t on the y. Sounds logical right? I'm not sure, what to expect and thus have no way to validate my results. On the other hand i think my history method is wrong. Any help would be appreciated. (Rungler code from https://cycling74.com/forums/sharing-is-rungling-stepped-havoc-in-gen)
