Timeline Graph
The timeline graph is a graphical representation of the events that happened during your time window.
Unlike the event list, which doesn't give you any idea of when or how often the events occurred, the timeline graph shows each incident.
Event Icons
There are a number of different icons you might see on the Timeline.
Interacting with the Timeline
Hovering your mouse over any of the icons on the timeline will give you details about what event happened, when, and which assets it happened to.
Left-click on the icon to lock your tooltip in place - this will let you click on the asset names and event descriptions, so you can see them in the Data Explorer.
Interacting with the Legend
At the bottom of the screen are lists of the different properties in your timeline and some of the different types of event. Clicking on the checkboxes will toggle those particular properties or types on and off.
This allows you to remove excess noise and focus on specific issues.
