Views an OC-DFG (object-centric directly-follows graph) with the provided configuration.

Object-centric directly-follows multigraphs are a composition of directly-follows graphs for the single object type, which can be annotated with different metrics considering the entities of an object-centric event log (i.e., events, unique objects, total objects).

Parameters:

  • ocdfg – Object-centric directly-follows graph

  • annotation (str) – The annotation to use for the visualization. Values: - “frequency”: frequency annotation - “performance”: performance annotation

  • act_metric (str) – The metric to use for the activities. Available values: - “events” => number of events (default) - “unique_objects” => number of unique objects - “total_objects” => number of total objects

  • edge_metric (str) – The metric to use for the edges. Available values: - “event_couples” => number of event couples (default) - “unique_objects” => number of unique objects - “total_objects” => number of total objects

  • act_threshold (int) – The threshold to apply on the activities frequency (default: 0). Only activities having a frequency >= than this are kept in the graph.

  • edge_threshold (int) – The threshold to apply on the edges frequency (default 0). Only edges having a frequency >= than this are kept in the graph.

  • performance_aggregation (str) – The aggregation measure to use for the performance: mean, median, min, max, sum

  • format (str) – The format of the output visualization (if html is provided, GraphvizJS is used to render the visualization in an HTML page)

  • bgcolor (str) – Background color of the visualization (default: white)

  • rankdir (str) – sets the direction of the graph (“LR” for left-to-right; “TB” for top-to-bottom)
