How to show node name in Matplotlib graphs using networkx?
To show node name in graphs using networkx, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Initialize a graph with edges, name, or graph attributes.
- Add multiple nodes using add_nodes_from() method.
- Add all the edges using add_edge_from() method.
- Draw the graph G with Matplotlib using draw() method. Set with_labels to True.
- To display the graph, we can use show() method.
Example
import matplotlib.pylab as plt import networkx as nx plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True G = nx.DiGraph() G.add_nodes_from([1, 2, 3, 4]) G.add_edges_from([(1, 2), (2, 1), (2, 3), (1,4), (3,4)]) nx.draw(G, with_labels=True) plt.show()
