pm4py.visualization.dfg.util.dfg_gviz.get_activities_color(activities_count)[source]#

Get frequency color for attributes

Parameters#

activities_count: Count of attributes in the log

Returns#

activities_color: Color assigned to attributes in the graph

pm4py.visualization.dfg.util.dfg_gviz.get_activities_color_serv_time(serv_time)[source]#

Gets the color for the activities based on the service time

Parameters#

serv_time: Service time

Returns#

act_color: Dictionary associating each activity to a color based on the service time

pm4py.visualization.dfg.util.dfg_gviz.get_min_max_value(dfg)[source]#

Gets min and max value assigned to edges in DFG graph

Parameters#

dfg: Directly follows graph

Returns#

min_value: Minimum value in directly follows graph
max_value: Maximum value in directly follows graph

pm4py.visualization.dfg.util.dfg_gviz.assign_penwidth_edges(dfg)[source]#

Assign penwidth to edges in directly-follows graph

Parameters#

dfg: Direcly follows graph

Returns#

penwidth: Graph penwidth that edges should have in the direcly follows graph

pm4py.visualization.dfg.util.dfg_gviz.graphviz_visualization(activities_count, dfg, image_format='png', measure='frequency', max_no_of_edges_in_diagram=100000, start_activities=None, end_activities=None, serv_time=None, font_size='12', bgcolor='white', rankdir='LR')[source]#

Do GraphViz visualization of a DFG graph

Parameters#

activities_count: Count of attributes in the log (may include attributes that are not in the DFG graph)
dfg: DFG graph
image_format: GraphViz should be represented in this format
measure: Describes which measure is assigned to edges in direcly follows graph (frequency/performance)
max_no_of_edges_in_diagram: Maximum number of edges in the diagram allowed for visualization
start_activities: Start activities of the log
end_activities: End activities of the log
serv_time: For each activity, the service time in the log
font_size: Size of the text on the activities/edges
bgcolor: Background color of the visualization (i.e., ‘transparent’, ‘white’, …)
rankdir: Direction of the graph (“LR” for left-to-right; “TB” for top-to-bottom)

Returns#

viz: Digraph object
