Change Attributes of a NetworkX Matplotlib Graph Drawing

To change the attributes of a netwrokx/matplotlib graph drawing, we can take the following steps −

Steps

• Set the figure size and adjust the padding between and around the subplots.

• Initialize a graph with edges, name, or graph attributes.

• Add the graph's attributes. Add an edge between u and v.

• Get the edge attributes from the graph.

• Position the nodes with circles.

• Draw the graph G with Matplotlib.

• To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
import networkx as nx

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

G = nx.Graph()
G.add_edge(0, 1, color='r', weight=2)
G.add_edge(1, 2, color='g', weight=4)
G.add_edge(2, 3, color='b', weight=6)
G.add_edge(3, 4, color='y', weight=3)
G.add_edge(4, 0, color='m', weight=1)

colors = nx.get_edge_attributes(G, 'color').values()
weights = nx.get_edge_attributes(G, 'weight').values()
pos = nx.circular_layout(G)

nx.draw(G, pos,
   edge_color=colors,
   width=list(weights),
   with_labels=True,
   node_color='lightgreen')

plt.show()
