plot.geometry(ret_velocity=False, data_atoms=None, species_as_Z=False, *, axes=['x', 'y', 'z'], atoms=None, atoms_style=[], atoms_scale=1.0, atoms_colorscale=None, drawing_mode=None, bind_bonds_to_ats=True, points_per_bond=20, bonds_style={}, bonds_scale=1.0, bonds_colorscale=None, show_atoms=True, show_bonds=True, show_cell='box', cell_style={}, nsc=(1, 1, 1), atoms_ndim_scale=(16, 16, 1), bonds_ndim_scale=(1, 1, 10), dataaxis_1d=None, arrows=(), backend='plotly')

Calls read_geometry and creates a GeometryPlot from its output.

Parameters:
  • ret_velocity (bool) – also return the velocities in the file

  • data_atoms (Optional[Atoms, Geometry]) – an object containing the basis information, is useful to overwrite the atoms object contained in the geometry.

  • species_as_Z (bool) – Deprecated, it does nothing!

  • axes (Axes) – The axes to project the geometry to.

  • atoms (AtomsIndex) – The atoms to plot. If None, all atoms are plotted.

  • atoms_style (Sequence[AtomsStyleSpec]) – List of style specifications for the atoms. See the showcase notebooks for examples.

  • atoms_scale (float) – Scaling factor for the size of all atoms.

  • atoms_colorscale (Optional[Colorscale]) – Colorscale to use for the atoms in case the color attribute is an array of values. If None, the default colorscale is used for each backend.

  • drawing_mode (Literal['scatter', 'balls', None]) – The method used to draw the atoms.

  • bind_bonds_to_ats (bool) – Whether to display only bonds between atoms that are being displayed.

  • points_per_bond (int) – When the points are drawn using points instead of lines (e.g. in some frameworks to draw multicolor bonds), the number of points used per bond.

  • bonds_style (StyleSpec) – Style specification for the bonds. See the showcase notebooks for examples.

  • bonds_scale (float) – Scaling factor for the width of all bonds.

  • bonds_colorscale (Optional[Colorscale]) – Colorscale to use for the bonds in case the color attribute is an array of values. If None, the default colorscale is used for each backend.

  • show_atoms (bool) – Whether to display the atoms.

  • show_bonds (bool) – Whether to display the bonds.

  • show_cell (Literal['box', 'axes', False]) – Mode to display the cell. If False, the cell is not displayed.

  • cell_style (StyleSpec) – Style specification for the cell. See the showcase notebooks for examples.

  • nsc (tuple[int, int, int]) – Number of unit cells to display in each direction.

  • atoms_ndim_scale (tuple[float, float, float]) – Scaling factor for the size of the atoms for different dimensionalities (1D, 2D, 3D).

  • bonds_ndim_scale (tuple[float, float, float]) – Scaling factor for the width of the bonds for different dimensionalities (1D, 2D, 3D).

  • dataaxis_1d (Optional[Union[np.ndarray, Callable]]) – Only meaningful for 1D plots. The data to plot on the Y axis.

  • arrows (Sequence[AtomArrowSpec]) – List of arrow specifications to display. See the showcase notebooks for examples.

  • backend – The backend to use to generate the figure.

read_geometry

The method called to get the data.

read(*args, **kwargs)

Generic read method which should be overloaded in child-classes

Parameters:

kwargs – keyword arguments will try and search for the attribute read_<> and call it with the remaining **kwargs as arguments.

read_data()

Returns an array with the velocities from the XV file

Return type:

numpy.ndarray

read_geometry(ret_velocity=False, atoms=None, species_as_Z=False)[source]

Returns a Geometry object from the XV file

Parameters:
  • ret_velocity (bool) – also return the velocities in the file

  • atoms (Optional[Atoms, Geometry]) – an object containing the basis information, is useful to overwrite the atoms object contained in the geometry.

  • species_as_Z (bool) – Deprecated, it does nothing!

Returns:

  • geometry (Geometry) – the geometry in the XV file

  • velocity (numpy.ndarray) – only if ret_velocity is true.

Return type:

Geometry

Returns Lattice object from the XV file

Return type:

Lattice

read_velocity()[source]

Returns an array with the velocities from the XV file

Return type:

numpy.ndarray

write(*args, **kwargs)

Generic write method which should be overloaded in child-classes

Parameters:

**kwargs – keyword arguments will try and search for the attribute write_ and call it with the remaining **kwargs as arguments.

write_geometry(geometry, fmt='.9f', velocity=None)[source]

Writes the geometry to the contained file

Parameters:
  • geometry (Geometry) – geometry to write in the XV file
