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)[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) – 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)
Returns:	\(dict\) of labels keyed on the edges
Return type:	dict
