graph_visual#

Module providing Graph visuals for rendering graphs.

Note

This module is providing vispy visuals only. See PlotGraph3d module for plotting.

class GraphLineVisual(graph, coordinates=None, color=None, vertex_colors=None, edge_colors=None, width=None, mode='gl')[source]#

Bases: LineVisual

Displays a graph in 3d using tube rendering for the edges

class GraphMeshVisual(graph, coordinates=None, radii=None, n_tube_points=8, default_radius=1, color=None, vertex_colors=None, edge_colors=None, mode='triangles', shading='smooth')[source]#

Bases: MeshVisual

Displays a graph in 3d using tube rendering for the edges

use_default_radii(coordinates, default_radius)[source]#
class GraphSphereVisual(graph, coordinates=None, radii=None, n_sphere_points=8, default_radius=1, color=None, vertex_colors=None, use_geometry=False, mode='triangles', shading='smooth')[source]#

Bases: MeshVisual

Render each vertex (or geometry sample-point) of a graph as a shaded 3-D sphere.

Parameters:

  • graph (Graph) – The graph to visualise.

  • coordinates (str | None) – Name of the (vertex- or geometry-)property that stores XYZ positions.

  • radii (str | 1-d array | None) – Property name or explicit per-point radii. Falls back to graph.vertex_radii() or default_radius.

  • n_sphere_points (int) – Number of longitudinal subdivisions (≥ 4). Latitudinal subdivisions are chosen automatically to give a roughly regular mesh.

  • default_radius (float) – Uniform radius to use when no radii are stored.

  • color (colour spec or array) – Global or per-vertex colours (same semantics as the other visuals).

  • vertex_colors (colour spec or array) – Global or per-vertex colours (same semantics as the other visuals).

  • use_geometry (bool) – If True plot every edge-geometry sample-point instead of the plain vertex set.

  • mode (str) – Passed straight to vispy.visuals.MeshVisual.

  • shading (str) – Passed straight to vispy.visuals.MeshVisual.
