Increasing the fpprec had no effect. I think my plot is good and the spikes are where they belong.

Subject: Re: [Maxima] The plot
I submitted it because I thought the spikes coming out of the sides would be the eigenvalues. The blue points are close to zero, the bluer the closer. The green points are 2.5 or higher. The grayish blue is somewhere in between. It is x by Energy for the x^4 potential, Is it not true that the spikes are the eigenvalues?
