Changes to a document in a case do not display in the histogram
of the Case History Visualizer.
Symptoms
When
you modify the properties of a case document, the event does not display
in the histogram area of the Case History Visualizer.
Resolving the problem
The
histogram is intended to display a summary of case activity. Because
document changes are not necessarily tied to an individual case, these
changes are not included in the case histogram. You can use the timeline
view to track Document Modified events.
