Timeline Visualizer widget

The Timeline Visualizer widget provides a visual representation of the extended history for a case. These representations show the progression of events, tasks, and work items over time for the case.

The Timeline Visualizer widget is included on the Case Details page by default. You can also include it on the Work Details page.

The widget uses a horizontal bar, the timeline, to show the time duration of each task and work item for the current case. The widget uses vertical bars to represent events, such as filing a document into the current case or changing the properties of the current case. In addition, the widget includes an event density histogram that provides an overview of when in time case events occurred over the entire life of the current case.

By navigating through the events, tasks, and work items, you can use the extended history to determine the status of a specific case. By comparing the extended history for different cases, you can identify potential problems with the workflow that is defined for a case type. For example, you might notice that delays tend to occur during the review step in a particular task. You can then determine an approach to reduce this delay.

To use the Timeline Visualizer, a case history store must be enabled and configured. Use the IBM® Case Manager administration client to configure the extended history. When you configure the extended history, you create the Case History table and select the properties to configure properties auditing. In addition, consider excluding properties whose value is unlikely to change. Excluding such properties reduces clutter in the widget, avoids wasting disk space, and helps performance. Users can still get the values of these properties from the case objects themselves.

By default, the Timeline Visualizer widget initially displays only a high-level timeline that shows the case events. The user can then expand the widget to view an event histogram or the task list for the case. The event histogram shows the density and distribution of case events. The task details can be further expanded to show the work items for each task. The widget switches to full-page mode when it is expanded. You can configure this widget so that the histogram and task list are expanded by default.

The widget initially displays a time range that is based on the number of events that you specify in the widget settings. A user can change the time range by using sliders in the timeline.

By default, the history events are collected every 2 minutes from the server. Therefore, there is a slight delay before the events are displayed in the Timeline Visualizer widget.
