Plastic SCM statistics tool is the best way of showing the daily changes made by users on each item. This information can be also retrieved from the query system but the statistics menu offers graphical interactive results.

The application shows the changes that each user has done and which items have changed, which allows you to see the most active users or the items that carry a higher workload. And furthermore...the application is interactive, whenever a user is selected, his workload is divided into as many parts as items that the user has changed (as shown on the right side of the image). And on the item´s side the changes done by that particular user on each of the items is highlighted, showing the items on which the user invests more or less time.

We can see the same interaction on the item´s side: when an item is selected, it is divided into as many parts as users who have modified it and on the users´graphic the changes done on that item will be highlighted.
