dwave_networkx.drawing.pegasus_layout.pegasus_layout¶
- pegasus_layout(G, scale=1.0, center=None, dim=2, crosses=False)[source]¶
Positions the nodes of graph G in a Pegasus topology.
NumPy is required for this function.
- Parameters
G (NetworkX graph) – A Pegasus graph or a subgraph of a Pegasus graph, as produced by the
dwave_networkx.pegasus_graph()
function.scale (float (default 1.)) – Scale factor. A setting of
scale = 1
fits all positions within [0, 1] on the x-axis and [-1, 0] on the y-axis.center (None or array (default None)) – Coordinates of the top left corner.
dim (int (default 2)) – Number of dimensions. When dim > 2, all extra dimensions are set to 0.
crosses (boolean (optional, default False)) – If True, \(K_{4,4}\) subgraphs are shown in a cross rather than L configuration. Ignored if G is defined with
nice_coordinates=True
.
- Returns
pos – Positions as a dictionary keyed by node.
- Return type
Examples
This example gives the positions of a Pegasus lattice of size 2.
>>> G = dnx.pegasus_graph(2) >>> pos = dnx.pegasus_layout(G)
