Trends:
On the Trend tab, the user can select the trend they wish to display. Filter through multiple trends by selecting Locations or Units, or both.

Note it's recommended that you don't add more than 5 for performance reasons. Rollup Type, Chart Type, and Chart color can also be selected

Use the Events tab to add or remove events by entering the event name and the date of the event. Example: “Lighting Retrofit Completed on 2/23/2011”.
