dwave_networkx.drawing.pegasus_layout.draw_pegasus_embedding¶
- draw_pegasus_embedding(G, *args, **kwargs)[source]¶
Draws an embedding onto Pegasus graph
G
.- Parameters
G (NetworkX graph) – Pegasus graph or a subgraph of a Pegasus graph as produced by the
dwave_networkx.pegasus_graph()
function.emb (dict) – Chains as a dict of the form
{qubit: chain, ...}
, where qubits are nodes inG
and chains are iterables of qubit labels.embedded_graph (NetworkX graph (optional, default None)) – Graph that contains all keys of the
emb
parameter as nodes. If specified, edges ofG
are considered interactions if and only if (1) they exist between two chains of theemb
parameter and (2) their keys are connected by an edge in this graph. If given, only the couplers between chains based on this graph are displayed.interaction_edges (list (optional, default None)) – Interactions as a list of edges. If specified, only these couplers are displayed.
show_labels (boolean (optional, default False)) – If True, each chain in the
emb
parameter is labelled with its key.chain_color (dict (optional, default None)) – Colors as a dict of the form
{node: rgba_color, ...}
associated with each key in theemb
parameter, where colors are length-4 tuples of floats between 0 and 1, inclusive. If None, each chain is assigned a different color.unused_color (tuple (optional, default (0.9,0.9,0.9,1.0))) – Color for graph
G
’s nodes that are not part of chains, and edges that are neither chain edges nor interactions. If None, these nodes and edges are not shown.crosses (boolean (optional, default False)) – If True, \(K_{4,4}\) subgraphs are shown in a cross rather than an L configuration. Ignored, if
G
is defined withnice_coordinates=True
.overlapped_embedding (boolean (optional, default False)) – If True, chains in the
emb
parameter may overlap (contain the same vertices inG
), and these overlaps are displayed as concentric circles.kwargs (optional keywords) – Parameters in
draw_networkx()
, except for thepos
parameter. If thelinear_biases
orquadratic_biases
parameters are specified, thedraw_networkx()
node_color
oredge_color
parameters are ignored.
