-
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=None, bbox=None, horizontalalignment='center', verticalalignment='center', ax=None, rotate=True)[source]¶ Draw edge labels.
- Parameters
G (graph) – A networkx graph
pos (dictionary) – A dictionary with nodes as keys and positions as values. Positions should be sequences of length 2.
ax (Matplotlib Axes object, optional) – Draw the graph in the specified Matplotlib axes.
alpha (float or None) – The text transparency (default=None)
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)
horizontalalignment ({‘center’, ‘right’, ‘left’}) – Horizontal alignment (default=’center’)
verticalalignment ({‘center’, ‘top’, ‘bottom’, ‘baseline’, ‘center_baseline’}) – Vertical alignment (default=’center’)
ax (Matplotlib Axes object, optional) – Draw the graph in the specified Matplotlib axes.
- Returns
dict
of labels keyed on the edges- Return type
Examples
>>> G = nx.dodecahedral_graph() >>> edge_labels = nx.draw_networkx_edge_labels(G, pos=nx.spring_layout(G))
