To explore the time bar:

1. Ensure a **3D Perspective** view is displayed (see [Display data in the View pane](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11607344)).
2. On the **Data Management** tab at the bottom of the Nexus window, navigate to an existing database. You can do this by expanding the displayed hierarchy and using the **Go forward to the next node**, **Go back to the last node**, and **Move up one folder level** buttons > Macro (inline-media-image)

.
3. In the **Name** column, double-click the trial that you want to load.   
Nexus opens the trial.
4. On the time bar, click the **Play** button or drag the current time indicator (blue vertical line) to play back offline capture data. To crop a trial (restrict playback to a range of frames), you can drag the Start and End Range indicators (the blue triangles at the top of the timeline) along the time bar.
5. To hide or display the **Data Management** window, double-click the **Data Management** tab at the bottom of the Nexus window.

> ✅ **Tip**   
> ✅ In addition to using the time bar to view and navigate trials, you can also use it to:  
> ✅ • View data quality as a heat map. For more information, see [Review trial data using the time bar](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11603456/Review+data+quality#ReviewTrialWithTimebar).  
> ✅ • Create and manage events (for example, a foot striking a force plate, or a joint attaining a specified angle, etc). For more information, see [Add events to trials](https://vicon-help.atlassian.net/wiki/spaces/Nexus216/pages/11608258).
