Access the visualizer

From your researcher dashboard, click the Data Visualization tab. By default, you will land on the Summary page. The Adherence Card shows a bird’s-eye view of task completion. 


Select your data set

Use the left-hand sidebar to define what you want to see:

  • Participant: Choose a specific participant from the dropdown menu.
  • Duration: Select the date range you’d like to analyze.
  • Resolution: Choose how the data is aggregated.

    • Daily: View data points day-by-day.

    • Weekly: View data averaged by week.

    • Monthly: (Coming Soon).

 

💡Pro Tip

Click any circle on the Adherence chart to jump directly to the Time Series view for that specific day.

 


Viewing time series data

The Time Series view provides a detailed, minute-by-minute look at a participant’s 24-hour cycle.

Switch to time series

Click the Time Series toggle at the top of the Data Visualization page, or click a specific date from the Adherence card.

Navigate the timeline

  • Select Date: Use the date picker at the top center to change the day you are viewing.
  • Switch Participants: Use the Participant List on the left. You can use the Search bar or Filter by Tag (e.g., "Group A") to find participants quickly.
  • Adjust Zoom: Use the Select Duration slider located between the timeline and the data charts to zoom in on a specific window of time (e.g., 4:23 AM – 6:45 PM).

Analyze metrics

Scroll down to view specific data charts like BBI (Beat-to-Beat Interval), Stress, Sleep Actigraphy or Heart Rate.

  • Manual Y-Axis: Toggle this on to set specific Min/Max values for a clearer view of data fluctuations.
  • Event Markers: Toggle Show task marker to see exactly when a participant performed a task (like "Drink Coffee" or "Meditation") relative to their physiological data.

Customizing your dashboard

You can clean up your view by showing only the metrics relevant to your study.

  1. Look for the Data Cards section (left sidebar in Summary view) or the Layout icon Button (top right in Time Series).

  2. Check or uncheck the metrics you wish to see (e.g., Steps, Stress, Sleep).

  3. In Time Series view, click Save Settings to keep your preferred layout for future sessions.


FAQs

Can I visualize data for an entire group at once?

Currently, the visualizer focuses on individual participant data. To see group-level trends, you'll need to export the data and use a statistical tool (like R, Python or Excel).

Why is some data missing from the charts?

Data only appears if the participant synced their device and completed the tasks. If the data is empty, the participant may not have worn their device or synced it recently.

Can I change the order of the data cards?

Currently, the cards appear in a fixed order. However, you can use the "Show/Hide" feature to remove any cards that aren't necessary for your analysis to make the dashboard easier to manage.

Can I export the charts?

Currently, the data charts can't be exported but that feature is in development.
