One timeline can drive several PivotTables at once
Right-clicking a timeline and choosing "Report Connections" lets you link it to every PivotTable in the workbook that's built from the same source data, so dragging the timeline once filters all of them together instead of adjusting each table's date filter separately. That's especially useful in a dashboard made up of several related PivotTables that should always show the same time period.
Switching the time unit reshapes what the bar represents
The unit selector in the corner of the timeline lets you switch between Days, Months, Quarters, and Years, and each setting changes what a single bar on the timeline represents -- a bar might mean one month at the Months setting but one quarter at the Quarters setting. Picking a coarser unit like Quarters or Years makes it faster to scan a long multi-year dataset, while Days or Months suits narrowing in on a specific short period.
Frequently Asked Questions
Can I switch between monthly, quarterly, and yearly views?
Yes. The unit selector in the top-right corner of the timeline lets you switch between Day, Month, Quarter, and Year.
Can it filter more than one PivotTable at the same time?
Yes. Right-click the timeline and choose "Report Connections" to apply the same filter simultaneously to every PivotTable built from the same source data.
