draw_networkx_nodes(G, pos, nodelist=None, node_size=300, node_color='r', node_shape='o', alpha=1.0, cmap=None, vmin=None, vmax=None, ax=None, linewidths=None, label=None, **kwds)[source]

Draw the nodes of the graph G.

This draws only the nodes 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.

ax : Matplotlib Axes object, optional

Draw the graph in the specified Matplotlib axes.

nodelist : list, optional

Draw only specified nodes (default G.nodes())

node_size : scalar or array

Size of nodes (default=300). If an array is specified it must be the same length as nodelist.

node_color : color string, or array of floats

Node color. Can be a single color format string (default=’r’), or a sequence of colors with the same length as nodelist. If numeric values are specified they will be mapped to colors using the cmap and vmin,vmax parameters. See matplotlib.scatter for more details.

node_shape : string

The shape of the node. Specification is as matplotlib.scatter marker, one of ‘so^>v<dph8’ (default=’o’).

alpha : float

The node transparency (default=1.0)

cmap : Matplotlib colormap

Colormap for mapping intensities of nodes (default=None)

vmin,vmax : floats

Minimum and maximum for node colormap scaling (default=None)

linewidths : [None | scalar | sequence]

Line width of symbol border (default =1.0)

label : [None| string]

Label for legend

Returns :


\(PathCollection\) of the nodes.
