graphistry.plotter module¶

class graphistry.plotter.Plotter¶

Bases: future.types.newobject.newobject

Graph plotting class.

Created using Graphistry.bind().

Chained calls successively add data and visual encodings, and end with a plot call.

To streamline reuse and replayable notebooks, Plotter manipulations are immutable. Each chained call returns a new instance that derives from the previous one. The old plotter or the new one can then be used to create different graphs.

The class supports convenience methods for mixing calls across Pandas, NetworkX, and IGraph.

bind(source=None, destination=None, node=None, edge_title=None, edge_label=None, edge_color=None, edge_weight=None, point_title=None, point_label=None, point_color=None, point_size=None)¶

Relate data attributes to graph structure and visual representation.

To facilitate reuse and replayable notebooks, the binding call is chainable. Invocation does not effect the old binding: it instead returns a new Plotter instance with the new bindings added to the existing ones. Both the old and new bindings can then be used for different graphs.

Parameters:	source (String.) – Attribute containing an edge’s source ID destination (String.) – Attribute containing an edge’s destination ID node (String.) – Attribute containing a node’s ID edge_title (HtmlString.) – Attribute overriding edge’s minimized label text. By default, the edge source and destination is used. edge_label (HtmlString.) – Attribute overriding edge’s expanded label text. By default, scrollable list of attribute/value mappings. edge_color (String.) – Attribute overriding edge’s color. See palette definitions for values. Based on Color Brewer. edge_weight (String.) – Attribute overriding edge weight. Default is 1. Advanced layout controls will relayout edges based on this value. point_title (HtmlString.) – Attribute overriding node’s minimized label text. By default, the node ID is used. point_label (HtmlString.) – Attribute overriding node’s expanded label text. By default, scrollable list of attribute/value mappings. point_color (Integer.) – Attribute overriding node’s color. See palette definitions for values. Based on Color Brewer. point_size (HtmlString.) – Attribute overriding node’s size. By default, uses the node degree. The visualization will normalize point sizes and adjust dynamically using semantic zoom.
Returns:	Plotter.
Return type:	Plotter.

Example: Minimal

import graphistry
g = graphistry.bind()
g = g.bind(source='src', destination='dst')

Example: Node colors

import graphistry
g = graphistry.bind()
g = g.bind(source='src', destination='dst',
           node='id', point_color='color')

Example: Chaining

import graphistry
g = graphistry.bind(source='src', destination='dst', node='id')

g1 = g.bind(point_color='color1', point_size='size1')

g.bind(point_color='color1b')

g2a = g1.bind(point_color='color2a')
g2b = g1.bind(point_color='color2b', point_size='size2b')

g3a = g2a.bind(point_size='size3a')
g3b = g2b.bind(point_size='size3b')

In the above Chaining example, all bindings use src/dst/id. Colors and sizes bind to:

g: default/default
g1: color1/size1
g2a: color2a/size1
g2b: color2b/size2b
g3a: color2a/size3a
g3b: color2b/size3b

edges(edges)¶

Specify edge list data and associated edge attribute values.

Parameters:	edges – Edges and their attributes.
Returns:	Plotter.
Return type:	Plotter.

Example

import graphistry

    .bind(source='src', destination='dst')
    .edges(df)
    .plot()

graph(ig)¶

Specify the node and edge data.

Parameters:	ig (NetworkX graph or an IGraph graph.) – Graph with node and edge attributes.
Returns:	Plotter.
Return type:	Plotter.

igraph2pandas(ig)¶

Under current bindings, transform an IGraph into a pandas edges dataframe and a nodes dataframe.

Example

import graphistry
g = graphistry.bind()

es = pandas.DataFrame({'src': [0,1,2], 'dst': [1,2,0]})
g = g.bind(source='src', destination='dst').edges(es)

ig = g.pandas2igraph(es)
ig.vs['community'] = ig.community_infomap().membership

(es2, vs2) = g.igraph2pandas(ig)
g.nodes(vs2).bind(point_color='community').plot()

networkx2pandas(g)¶

nodes(nodes)¶

Specify the set of nodes and associated data.

Must include any nodes referenced in the edge list.

Parameters:	nodes – Nodes and their attributes.
Returns:	Plotter.
Return type:	Plotter.

Example

import graphistry

es = pandas.DataFrame({'src': [0,1,2], 'dst': [1,2,0]})

    .bind(source='src', destination='dst')
    .edges(es)

vs = pandas.DataFrame({'v': [0,1,2], 'lbl': ['a', 'b', 'c']})
g = g.bind(node='v').nodes(vs)

g.plot()

pandas2igraph(edges, directed=True)¶

Convert a pandas edge dataframe to an IGraph graph.

Uses current bindings. Defaults to treating edges as directed.

Example

import graphistry
g = graphistry.bind()

es = pandas.DataFrame({'src': [0,1,2], 'dst': [1,2,0]})
g = g.bind(source='src', destination='dst')

ig = g.pandas2igraph(es)
ig.vs['community'] = ig.community_infomap().membership
g.bind(point_color='community').plot(ig)

plot(graph=None, nodes=None, name=None)¶

Upload data to the Graphistry server and show as an iframe of it.

name, Uses the currently bound schema structure and visual encodings. Optional parameters override the current bindings.

When used in a notebook environment, will also show an iframe of the visualization.

Parameters:	graph (Pandas dataframe, NetworkX graph, or IGraph graph.) – Edge table or graph. nodes (Pandas dataframe.) – Nodes table.

Example: Simple

import graphistry
es = pandas.DataFrame({'src': [0,1,2], 'dst': [1,2,0]})
graphistry
    .bind(source='src', destination='dst')
    .edges(es)
    .plot()

Example: Shorthand

import graphistry
es = pandas.DataFrame({'src': [0,1,2], 'dst': [1,2,0]})
graphistry
    .bind(source='src', destination='dst')
    .plot(es)

settings(height=None, url_params={})¶

Specify iframe height and add URL parameter dictionary.

The library takes care of URI component encoding for the dictionary.

Parameters:	height (Integer.) – Height in pixels. url_params (Dictionary) – Dictionary of querystring parameters to append to the URL.
