Detail the contextual information specific to the issue; i.e. Product, Version, Agent, System, etc.
Describe the problem, from the user perspective
I was unable to create a chart with multiple tests using the metric DOM Interactive and the Group By setting Aggregate All.
Clearly list the Steps to resolve the issue
To be able to chart the DOM Interactive metric grouped by Aggregate All, all tests must have Include client (non-network) time in results enabled. This setting is available for Backbone, Private Last Mile, and Mobile tests.
Note the underlying reason for the problem
All of the tests being charted did not include the client time in the results.
