The Activity Comparison Report lets you compare multiple users across multiple metrics.
You can filter the report by date range, user, Smart View. You can also select a comparison date range to see the percent change in each metric between the two time periods. These filters work the same they do in the Activity Overview Report.
You can sort the users in ascending or descending over based on any column in the Activity Comparison report. (This includes the Team Members column, so you are able to sort users alphabetically.)
You can adjust the sort by clicking the arrow buttons on the column headers.
You can export your Activity Comparison Report for further analysis. Click the "..." button at the very top of the page to export as either a CSV or JSON file.
