Plotting a cell

This page explains how to use wulfric.PlotlyEngine.plot_cell() on the simple example of the cubic cell

We use FCC cell as an example.

import wulfric

cell = wulfric.cell.SC_FCC(a=3)

To display the cell with the default settings use

pe = wulfric.PlotlyEngine(_sphinx_gallery_fix=True)

pe.plot_cell(cell=cell)

pe.show()

Legend and style

pe = wulfric.PlotlyEngine(_sphinx_gallery_fix=True)

pe.plot_cell(cell=cell, legend_label="Direct cubic cell", color="green")

pe.show()

Hiding lattice vectors

pe = wulfric.PlotlyEngine(_sphinx_gallery_fix=True)

pe.plot_cell(cell=cell, plot_vectors=False)

pe.show()

Shifting origin point

By default lattice vectors are plotted from the \((0, 0, 0)\) of the global of the global reference frame. One can shift this reference point.

pe = wulfric.PlotlyEngine(_sphinx_gallery_fix=True)

# shift is given in the absolute units of the global reference frame
pe.plot_cell(cell=cell, shift=(1, -1, 0.5))

pe.show()

Two cells

One can plot any number of cells on one instance of wulfric.PlotlyEngine. For example, one can plot direct and reciprocal cell together

pe = wulfric.PlotlyEngine(_sphinx_gallery_fix=True)

# Plot direct cell
pe.plot_cell(cell=cell, legend_label="Direct cell", color="blue")

# Get reciprocal cell
rcell = wulfric.cell.get_reciprocal(cell=cell)

# Plot reciprocal cell
pe.plot_cell(cell=rcell, legend_label="Reciprocal cell", color="red")

pe.show()
