Annotations

In the Plan view from the first level drop-down menu in a project, click the Annotations drop-down menu.

From here, Annotations can be changed by clicking the various options, which will update the information displayed on the Gantt Chart.

The Benchmark Analysis options can also be used to change what level or WBS elements the phase windows appear.

The phase window indicates the time period that the benchmark falls within in the Knowledge Library project, conformed to the current project using the current project's start date and knowledge tags normalizers.  For items that have the phase window showing, there is also a set of brackets indicating a range that the complete date of a summary WBS element is expected to fall within. 

This is based on the % of tolerance defined in the project settings, the start date of the summary WBS in the current project, and the duration of the benchmark from the Knowledge Library.
