bqplot.marks.Graph

class bqplot.marks.Graph(**kwargs)[source]

Graph with nodes and links.

node_data

List – list of node attributes for the graph

numpy.ndarray of shape(len(nodes), len(nodes)) – link data passed as 2d matrix

List – list of link attributes for the graph

charge

int (default: -300) – charge of force layout. Will be ignored when x and y data attributes are set

float (default: 100) – link distance in pixels between nodes. Will be ignored when x and y data attributes are set

{‘arc’, ‘line’, ‘slant_line’} (default: ‘arc’) – Enum representing link type

directed

bool (default: True) – directed or undirected graph

bool (default: True) – highlights incoming and outgoing links when hovered on a node

colors

list (default: CATEGORY10) – list of node colors

Data Attributes
x

numpy.ndarray (default: []) – abscissas of the node data points (1d array)

y

numpy.ndarray (default: []) – ordinates of the node data points (1d array)

color

numpy.ndarray or None (default: None) – color of the node data points (1d array).

numpy.ndarray of shape(len(nodes), len(nodes)) – link data passed as 2d matrix
