I think we are saying the same. Total energy constant means that you can
always write the equilibrium equation, including the external work done on
the system. With care to the signs, of course. So thanks cause you remind me
I could be wrong in that sense and changing the sign of externalWork the
result looks better (attached).

BTW, Q. : how do you initialize to zero a variable you were storing in
plotData()? How to do it in python?
