Bases: GridPlot

Plots a wavefunction in real space.

Parameters:

eigenstate – The eigenstate object containing information about eigenstates.
i – The index of the eigenstate to plot.
geometry – Geometry to use to project the eigenstate to real space. If None, the geometry associated with the eigenstate is used.
grid_prec – The precision of the grid where the wavefunction is projected.
grid – The grid to plot.
axes – The axes to project the grid to.
represent – The representation of the grid to plot.
transforms – List of transforms to apply to the grid before plotting.
reduce_method – The method used to reduce the grid axes that are not displayed.
boundary_mode – The method used to deal with the boundary conditions. Only used if the grid is to be orthogonalized. See scipy docs for more info on the possible values.
nsc – The number of unit cells to display in each direction.
interp – The interpolation factor to use for each axis to make the grid smoother.
isos – List of isosurfaces or isocontours to plot. See the showcase notebooks for examples.
smooth – Whether to ask the plotting backend to make an attempt at smoothing the grid display.
colorscale – Colorscale to use for the grid display in the 2D representation. If None, the default colorscale is used for each backend.
crange – Min and max values for the colorscale.
cmid – The value at which the colorscale is centered.
show_cell – Method used to display the unit cell. If False, the cell is not displayed.
cell_style – Style specification for the cell. See the showcase notebooks for examples.
x_range – The range of the x axis to take into account. Even if the X axis is not displayed! This is important because the reducing operation will only be applied on this range.
y_range – The range of the y axis to take into account. Even if the Y axis is not displayed! This is important because the reducing operation will only be applied on this range.
z_range – The range of the z axis to take into account. Even if the Z axis is not displayed! This is important because the reducing operation will only be applied on this range.
plot_geom – Whether to plot the associated geometry (if any).
geom_kwargs – Keyword arguments to pass to the geometry plot of the associated geometry.
backend – The backend to use to generate the figure.

__call__(*args, **kwargs): Call self as a function.

static evaluate_input_node(node: Node)

classmethod final_node_key(*args) → str: Returns the key of the final (output) node of the workflow.

classmethod find_node_key(node, *args) → str: Returns the identifier key of a node in this workflow

classmethod from_func(func: Callable | None = None, context: dict | None = None, module: str | None = None)

Builds a node from a function.

Parameters:

func (function, optional) – The function to be converted to a node.

If not provided, the return of this method is just a lambda function that expects the function. This is useful if you want to use this method as a decorator while also providing extra arguments (like the context argument).
context (dict, optional) – The context to be used as the default for the node class that will be created.

classmethod from_node_tree(output_node: Node, workflow_name: str | None = None)

Creates a workflow class from a node.

It does so by recursively traversing the tree in the inputs direction until it finds the leaves. All the nodes found are included in the workflow. For each node, inputs that are not nodes are connected to the inputs of the workflow.

Parameters:

output_node (Node) – The final node, that should be connected to the output of the workflow.
workflow_name (str, optional) – The name of the new workflow class. If None, the name of the output node will be used.

Returns:

Workflow – The newly created workflow class.
