How to compare to previous period
Simply click the date selector at the top right of a dashboard, choose your desired comparison period from the dropdown, then click "Apply".
Comparisons depend on the availability of historical data: If no data is available from the previous period or year, the comparison metric will display 0%.
- Previous Period: This compares to the same number of days prior to your current selection. If you choose "Last 7 days", you will see a comparison to the 7 days prior to the current 7 day period. If you choose "This month", you'll see a comparison to last month. If you choose a custom date range that spans 47 days, then the comparison will be to the previous 47 day period.
- Previous Year: This is based on the calendar year. If you choose "Last 7 days", then your comparison will be to the exact same calendar dates of the previous calendar year. If you choose "This month", you'll see a comparison to the same month for the previous calendar year. And so on.
Note: The "Compare to Previous" comparisons are generally displayed as either a percentage increase/decrease or an up/down number. The specific metrics used to calculate these numbers will vary based on the module and the metric.
