Time Filters

You can use Time Filters to filter your data by time. Time Filters also have an integrated timeline with playback functionality that updates as your change filter settings.

To create a simple time playback animation, visit the Time Playback documentation.

Create a Time Filter

1. Navigate to the Filters tab, then click Add Filter.

2. Select a field with a time tag.

The time filter requires data formatted in a standard time format.

If you have a column that represents temporal data, but Studio has not assigned it a time tag, use the parseTime expression to parse a string into a timestamp.

3. Configure your filter.

Upon creating a time filter, a timeline will appear in the map window. Click the Time Playback button on the filter panel (indicated by a clock icon) to bring the timeline under the filter panel. Click again to return the timeline to the map.

Learn more about animating your timeline in the Time Playback documentation.

Time Filter Sync

If you have several datasets with timestamp fields, you can synchronize the time playback across all selected datasets.

Add Synchronized Datasets to a Time Filter

Click the + Synced datasets button (located at the bottom of the time filter) to add a synchronized dataset to the time filter.

Foursquare Studio will automatically detect time fields from the other datasets, then synchronize them on the timeline.

Link Filter with Layer Timeline

Some layers in Foursquare Studio have their own animation component. For example, the trip layer can animate the path of moving subjects.

To link a layer animation to the time filter, click the + Link with the layer timeline button.

Animating with Linked Filter and Layer

Synchronized playback can be configured to optimize your animation.

Refer to the table below to view all possible synchronization behaviors, which are based on the Sync Timeline Window and Animation Window settings.
