draw_networkx_edge_labels

draw_networkx_edge_labels(G, pos, edge_labels=None, label_pos=0.5, font_size=10, font_color='k', font_family='sans-serif', font_weight='normal', alpha=1.0, bbox=None, ax=None, rotate=True, **kwds)

Draw edge labels.

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)

edge_labels : dictionary

Edge labels in a dictionary keyed by edge two-tuple of text labels (default=None). Only labels for the keys in the dictionary are drawn.

label_pos : float

Position of edge label along edge (0=head, 0.5=center, 1=tail)

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’)

bbox : Matplotlib bbox

Specify text box shape and colors.

clip_on : bool

Turn on clipping at axis boundaries (default=True)
