I'm in general agreement with John Denker - it can't actually matter how you plot; however there are a couple of points that I think are worth discussing. As was stated, YMMV, and I'm happy to learn of corrections to my misunderstandings.



I missed this conversation, but no matter, as I have nothing to add about graphing.  

However, for a time I was an amateur horologist and spent considerable time experimenting with pendula.  

I posted much here:

Several mechanics texts describe the spring oscillator coupled to a pendulum via support of the pendulum.  I built that apparatus.  The most accessible version is posted here.

bc   ….  thinks he’s the only person who had done this, at that time (ca 2013)


I had posted this much earlier.  IIRC, no one commented.
