Help with Time Series Animations

[RobertCox87]

I am trying to use the Time Series Animation tool to show a location's openings over time.  The goal is to display all locations as they open through time.  Each location has an opening date associated with it, but when I run the animation, it only displays the locations associated with each date and the existing locations disappear when the open date passes.  Is there a way to keep the previously opened locations displayed as the new ones are added?

To make the display cumulative rather than point in time, you have to disable the start time of the time span. Click on the start time and end time buttons (next to the calendar date selector buttons) in the Current Time group to change them from bars to arrows.

Point in time display:

Cumulative display:
