draw_networkx_edges(G, pos, edgelist=None, width=1.0, edge_color='k', style='solid', alpha=1.0, edge_cmap=None, edge_vmin=None, edge_vmax=None, ax=None, arrows=True, label=None, **kwds)¶
Draw the edges of the graph G.
This draws only the edges of the graph G.
- 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)
- cmap (edge) – 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.
- label ([None| string]) – Label for legend
of the edges
For directed graphs, “arrows” (actually just thicker stubs) are drawn at the head end. Arrows can be turned off with keyword arrows=False. Yes, it is ugly but drawing proper arrows with Matplotlib this way is tricky.
