Energy spectral density for free electrons in two dimensions in a magnetic field at zero temperature

At zero temperature, the electrons fill the lowest Landau levels. The highest Landau level is partially filled.

The δ-functions are approximated by rectangular pulses that are an energy wide. This makes the vertical axis somewhat arbitrary.
