Plotting bandsdosplot

This example illustrates how to utilize various configurations for plotting both band structures and density of states (DOS) side by side using the pyprocar package. It provides a structured way to explore and demonstrate different configurations for the bandsdosplot function.

Preparation

Before diving into plotting, we need to download the example files. Use the following code to do this. Once downloaded, specify the bands_dir and dos_dir to point to the location of the downloaded data.

Downloading example

bands_dir = pyprocar.download_example(save_dir='',
                             material='Fe',
                             code='vasp',
                             spin_calc_type='non-spin-polarized',
                             calc_type='bands')

dos_dir = pyprocar.download_example(save_dir='',
                             material='Fe',
                             code='vasp',
                             spin_calc_type='non-spin-polarized',
                             calc_type='dos')

import os
import pyprocar

bands_dir = f"{pyprocar.utils.ROOT}{os.sep}data{os.sep}examples{os.sep}Fe{os.sep}vasp{os.sep}non-spin-polarized{os.sep}bands"
dos_dir = f"{pyprocar.utils.ROOT}{os.sep}data{os.sep}examples{os.sep}Fe{os.sep}vasp{os.sep}non-spin-polarized{os.sep}dos"

# Section 1: Plain Mode with Default Settings
# ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#
# This section demonstrates how to plot both band structures and DOS side by side using default settings.
# The keywords that work for `bandsplot` and `dosplot` will also work in `bandsdosplot`.
# These keyword arguments can be set in `bands_settings` and `dos_settings` as demonstrated below.
#


bands_settings = {
                  'mode':'plain',
                  'fermi':5.599480, # This will overide the default fermi value found in bands directory
                  'dirname': bands_dir
                  }

dos_settings = {
               'mode':'plain',
               'fermi':5.599480,   # This will overide the default fermi value found in dos directory
               'dirname': dos_dir
                }

pyprocar.bandsdosplot(code='vasp',
                bands_settings=bands_settings,
                dos_settings=dos_settings,
                )
