Work log entries can be grouped for user, issue, project, epic or a work log attribute. By grouping by work log attribute, you can visualize how time is spend for various values of specified work log attribute. For example;
- You can visualize distribution of work logs between billable and non billable
- You can visualize distribution of work logs between work types, like development, testing etc.
Possibilities just depends on which work log attributes you have created.
