Without timeboxing, every widget you create will only display data for the entire life of the media. With timeboxing, you can narrow down your widgets to focus on specific moments in time.
Timeboxing Your Widget
You can timebox any widget, aside from the Engagement/Rewatch graph. It’s the last section in the widget options window.
Enabling timeboxing is as simple as hitting its switch, selecting your start date and end date, and saving.
The data displayed in your widget will now only be from within the dates that you selected.
