Visualizes an OC-DFG as a Graphviz di-graph

Parameters#

ocdfg

OC-DFG

parameters

Parameters of the algorithm: - Parameters.FORMAT => the format of the output visualization (default: “png”) - Parameters.BGCOLOR => the default background color (default: “bgcolor”) - Parameters.RANKDIR => direction of the graph (“LR” for left-to-right; “TB” for top-to-bottom) - Parameters.ACT_METRIC => 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

  • Parameters.EDGE_METRIC => 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

  • Parameters.ACT_THRESHOLD => the threshold to apply on the activities frequency (default: 0). Only activities

having a frequency >= than this are kept in the graph. - Parameters.EDGE_THRESHOLD => the threshold to apply on the edges frequency (default 0). Only edges having a frequency >= than this are kept in the graph. - Parameters.ANNOTATION => the annotation to use for the visualization. Values:

  • “frequency”: frequency annotation

  • “performance”: performance annotation

  • Parameters.PERFORMANCE_AGGREGATION_MEASURE => the aggregation measure to use for the performance:

    • mean

    • median

    • min

    • max

    • sum
