Plotting density of states

Plotting density example.

First download the example files with the code below. Then replace data_dir below.

Downloading example

 data_dir = pyprocar.download_example(save_dir='',
                             material='SrVO3',
                             code='vasp',
                             spin_calc_type='non-spin-polarized',
                             calc_type='fermi')

importing pyprocar and specifying local data_dir

import os

import pyprocar

data_dir = os.path.join(
    pyprocar.utils.DATA_DIR, "examples", "SrVO3", "vasp", "non-spin-polarized", "fermi"
)

Plain mode

pyprocar.dosplot(code="vasp", mode="plain", fermi=5.3017, dirname=data_dir)

            --------------------------------------------------------
            There are additional plot options that are defined in a configuration file.
            You can change these configurations by passing the keyword argument to the function
            To print a list of plot options set print_plot_opts=True

            Here is a list modes : plain , parametric , parameteric_line , stack , stack_orbitals , stack_species , overlay , overlay_orbitals , overlay_species
