networkx.drawing.nx_pylab.draw_networkx_labels(G, pos, labels=None, font_size=12, font_color='k', font_family='sans-serif', font_weight='normal', alpha=1.0, ax=None, **kwds)

Draw node labels on the graph G.

Parameters :

G : graph

A networkx graph

pos : dictionary, optional

A dictionary with nodes as keys and positions as values. If not specified a spring layout positioning will be computed. See networkx.layout for functions that compute node positions.

ax : Matplotlib Axes object, optional

Draw the graph in the specified Matplotlib axes.

alpha: float :

The text transparency (default=1.0)

labels: dictionary :

Node labels in a dictionary keyed by node of text labels (default=None)

font_size: int :

Font size for text labels (default=12)

font_color: string :

Font color string (default=’k’ black)

font_weight: string :

Font weight (default=’normal’)

font_family: string :

Font family (default=’sans-serif’)
