Process Overview Case Explorer

Screenshot of PMTk – the Process Mining Toolkit

Screenshot shows the Case Explorer, listing individual cases sorted by start time, with one case selected. Each row displays a case's start time, end time, cycle time, and activity sequence as color-coded chevrons. The Details for Case panel below the table shows the selected case's Case Attributes and Event Attributes tables.

The Case Explorer presents a paginated, case-level view of the entire event log. Each row represents one individual case, displaying its start time, end time, cycle time, and variant sequence as a series of color-coded activity chevrons. Unlike the Variant Explorer, which groups cases by their shared sequence, the Case Explorer treats every case individually, making it the primary view for inspecting specific cases and their attributes in detail.

Navigation between pages is handled via the page controls at the bottom of the table, which also indicate the total number of cases and the currently visible range. Click in the toolbar to open a search field for quickly locating a specific Case ID.

Inspect Attributes

Clicking anywhere on a case row (other than its checkbox) selects it as the active case, highlighting the row and opening a Details for Case panel below the table with two tables:

Case Attributes: every case-level attribute of the selected case, listed as Attribute / Value rows.
Event Attributes: every event-level attribute (e.g., Start Timestamp, Timestamp, Wait Time, Work Time, Wait + Work Time, Resource, and any custom attributes in the log) as rows, with one column per event in the case. Each column is headed by a color-coded chevron matching the corresponding activity in the case's variant sequence.

Case Explorer Configuration

The legend panel and configuration panel provide the following settings.

Setting	Description	Values
Color Scale	Controls how values are mapped to colors. Requires Decoration: Wait/Work/Wait+Work Time.	Linear (default) Distributed continuous and proportional across the full value range. Binned Grouped into discrete buckets, each assigned a uniform color.
Variants Style	Controls how variant rows are rendered.	Collapsed (default) Activities are shown as a compact chevron with a truncated labels. Compact Activities are shown as a colored squares without labels. Expanded Enlarged version of collapsed, showing a more of the label for each activity.
Show Labels	Toggles whether activity names are displayed inside the chevrons.	Disabled Enabled (default)
Displayed Information	Additional columns can be enabled or disabled to show supplementary statistics per variant. All enabled by default.	Selection Number of cases and its log percentage for each variant. Case ID Unique identifier of each case. Start Time Timestamp indicating when each case started. End Time Timestamp indicating when each case ended. Cycle Time Total duration of the case. Variant The activity sequence displayed using chevrons.
Activity Decoration	Determines how the color of each activity chevron is assigned.	Wait Time Work Time Wait + Work Time Activity Color (default)
Start/End Time Format	The display format of the Start Time and End Time columns can be configured independently.	Date (default) Date & hh:mm Date & hh:mm:ss
Duration Format	Controls the unit(s) used to display cycle time durations.	All Units (default) Two Units Single Unit (e.g., Days, Hours, Minutes)

Case Explorer Filtering

Cases can be selected using the checkboxes to the left of each row. The header checkbox selects or deselects all cases on the current page at once. With one or more cases selected, clicking on Filter Selected Cases in the toolbar opens the filter dialog, offering two modes:

Option	Effect
Positive: Keep Selected Cases	Retains only cases whose case ID matches one of the selected cases, removing all others from the event log.
Negative: Remove Selected Cases	Removes all cases whose case ID matches one of the selected cases, retaining the rest.

Clicking Apply in the dialog applies a Text Attributes Filter globally across all dashboards. You can clear or adjust the filter at any time through the filter controls in the top bar.
