fcapy.visualizer.Visualizer

class fcapy.visualizer.Visualizer(lattice=None, node_color='blue', cmap='Blues', node_alpha=1, node_linewidth=1, node_edgecolor='blue', cmap_min=None, cmap_max=None)

A class for visualizing the ConceptLattice

draw_networkx(...):

Draw a ConceptLattice line diagram with networkx package

get_plotly_figure(...):

Return a Plotly figure with the ConceptLattice line diagram

__init__(lattice=None, node_color='blue', cmap='Blues', node_alpha=1, node_linewidth=1, node_edgecolor='blue', cmap_min=None, cmap_max=None)

Initialize the Visualizer

Parameters

  • lattice (ConceptLattice) – A ConceptLattice to visualize

  • node_color (str or list of str) – A default color to use for ConceptLattice visualization (can be changed afterwards)

  • cmap (str) – Colormap to use for ConceptLattice visualization

  • node_alpha (float) – Transparency of nodes

  • node_linewidth (float) – Width of borderline (edge) around the nodes in a line diagram

  • node_edgecolor (float) – Color of borderline (edge) around the nodes in a line diagram

  • cmap_min (float) – The minimum value of a colormap

  • cmap_max (float) – The maximum value of a colormap

Methods

__init__([lattice, node_color, cmap, …])

Initialize the Visualizer

draw_networkx([draw_node_indices, …])

Draw line diagram of the ConceptLattice with networkx package

get_nodes_position([lattice])

draw_networkx(draw_node_indices=False, edge_radius=None, max_new_extent_count=3, max_new_intent_count=3)

Draw line diagram of the ConceptLattice with networkx package

Parameters

  • draw_node_indices (bool) – A flag whether to draw indexes of nodes inside the nodes

  • edge_radius (float) – A value of how much curve the edges on line diagram should be

  • max_new_extent_count (int) – A number of new objects in concept extent to draw
