The doping and energy evolution of the magnetic excitations of the electron-doped cuprate superconductor Pr0.88LaCe0.12CuO_4\ensuremath-\ensuremathδ in the superconducting state is studied based on the kinetic energy driven superconducting mechanism. It is shown that there is a broad commensurate scattering peak at low energy, then the resonance energy is located among this low energy commensurate scattering range. This low energy commensurate scattering disperses outward into a continuous ringlike incommensurate scattering at high energy. The theory also predicts a dome shaped doping dependent resonance energy.
