graphy.plotting - Module with graphical plotting functions

graphy.plotting.plot_graph(G, pos=None, colors=None, node_labels=None, node_size=0.04, edgescale=1.0, nodeopts={}, labelopts={}, arrowopts={}, bidir_arrows=True, cmap='Paired', vmin=None, vmax=None)

Plot a graphs. Supports both directed and undirected graphs. Undirected edges are drawn as lines while directed edges are drawn as arrows.

For example:

>>> from graphy import plotting
>>> import networkx as nx
>>> G=nx.karate_club_graph()
>>> plotting.plot_graph(G, pos=nx.spring_layout(G), colors=range(G.number_of_nodes()))

Parameters:

Gnetworkx Graph object or 2-d np.array

Graph to plot, either instance of networkx Graph or a 2-d connectivity matrix.

posdict

Dict specifying positions of nodes, as in {node: (x,y). If not provided, nodes are arranged along a circle.

colorslist of ints or list of RGBA values (default None)

Color(s) to use for node faces, if desired.

node_labelslist of strings (default None)

Labels to use for node labels, if desired.

node_sizefloat (default 0.05)

Size of nodes.

edgescalefloat (default 1.0)

Controls thickness of edges between nodes.

nodeoptsdict (default {})

Extra options to pass into plt.Circle call for plotting nodes.

labeloptsdict (default {})

Extra options to pass into plt.text call for plotting labels. Could be used to specify fontsize, for example.

arrowoptsdict (default {})

Extra options to pass into plt.arrow call for plotting edges.

bidir_arrowsbool (default True)

Whether to draw arrowheads when graph is directed and two nodes are connected bidirectionally.

cmapstring (default ‘Paired’)

Name of colormap to use.

vminfloat (default is minimum of colors)

Starting value to use for colormap.

vmaxfloat (default is minimum of colors)

Ending value to use for colormap.
