Sorry, but I was just in the process of just exploring the x^4 problem. I had no real goal at the time.

Well of course it does -- that was my point. Try the your method on
the x^2 oscillator and see if your method works where you know the
answer. I'm dubious that your graphical method will be all that good.
See my webpage for a picture of the time-dependent QM x^2 oscillator.
