Trend Analysis is a new feature from version 5.2. The system collects and forms history for all project properties and this capability allows you to view that content.

Simple set the type of analysis by selecting Project or Portfolio and the pre configured view from the pick list. and then refresh.  If the auto size of the cahrt is too big for your browser screen you can use the Full width button to resize it to your current screen size.

Remember you may need to move to different display tabs to see the correct type of display for your view.

This one here is a project  timeline chart for Benefits.

This one here is a Status history chart for the portfolio.

Views cannot be altered here, they will need to be changed in the windows app.
