docs: Plot the band structure and the DOS.
  
          Args:
              dos_pos: Index of the task from which the DOS should be obtained.
                       None is all DOSes should be displayed. Accepts integer or list of integers.
              method: String defining the method for the computation of the DOS.
              step: Energy step (eV) of the linear mesh.
              width: Standard deviation (eV) of the gaussian.
              kwargs: Keyword arguments passed to `plot` method to customize the plot.
  
          Returns:
              `matplotlib` figure.
