draw_networkx_edges
(G, pos, edgelist=None, width=1.0, edge_color='k', style='solid', alpha=1.0, arrowstyle='-|>', arrowsize=10, edge_cmap=None, edge_vmin=None, edge_vmax=None, ax=None, arrows=True, label=None, node_size=300, nodelist=None, node_shape='o', **kwds)[source]¶ Draw the edges of the graph G.
This draws only the edges of the graph G.
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.
- edgelist (collection of edge tuples) – Draw only specified edges(default=G.edges())
- width (float, or array of floats) – Line width of edges (default=1.0)
- edge_color (color string, or array of floats) – Edge color. Can be a single color format string (default=’r’), or a sequence of colors with the same length as edgelist. If numeric values are specified they will be mapped to colors using the edge_cmap and edge_vmin,edge_vmax parameters.
- style (string) – Edge line style (default=’solid’) (solid|dashed|dotted,dashdot)
- alpha (float) – The edge transparency (default=1.0)
- edge_ cmap (Matplotlib colormap) – Colormap for mapping intensities of edges (default=None)
- edge_vmin,edge_vmax (floats) – Minimum and maximum for edge colormap scaling (default=None)
- ax (Matplotlib Axes object, optional) – Draw the graph in the specified Matplotlib axes.
- arrows (bool, optional (default=True)) – For directed graphs, if True draw arrowheads. Note: Arrows will be the same color as edges.
- arrowstyle (str, optional (default=’-|>’)) – For directed graphs, choose the style of the arrow heads.
See :py:class:
matplotlib.patches.ArrowStyle
for more options. - arrowsize (int, optional (default=10)) – For directed graphs, choose the size of the arrow head head’s length and
width. See :py:class:
matplotlib.patches.FancyArrowPatch
for attributemutation_scale
for more info. - label ([None| string]) – Label for legend
Returns: - matplotlib.collection.LineCollection –
LineCollection
of the edges - list of matplotlib.patches.FancyArrowPatch –
FancyArrowPatch
instances of the directed edges - Depending whether the drawing includes arrows or not.
Notes
For directed graphs, arrows are drawn at the head end. Arrows can be turned off with keyword arrows=False. Be sure to include `node_size’ as a keyword argument; arrows are drawn considering the size of nodes.
Examples
>>> G = nx.dodecahedral_graph() >>> edges = nx.draw_networkx_edges(G, pos=nx.spring_layout(G))
>>> G = nx.DiGraph() >>> G.add_edges_from([(1, 2), (1, 3), (2, 3)]) >>> arcs = nx.draw_networkx_edges(G, pos=nx.spring_layout(G)) >>> alphas = [0.3, 0.4, 0.5] >>> for i, arc in enumerate(arcs): # change alpha values of arcs ... arc.set_alpha(alphas[i])
