We are estimating and logging the time for each subtask of every story. Manually I can access the report "Burndown Chart" for every past sprint, where I can find the values for "remaining time estimate" on top of the table with all logging events and "time spent" on the bottom of the same table in another column.
Is there a way to extract both values without all logging events and create an overview in the following form:
Sprint Remaining Time estimate Time Spent
Sprint01 510h 525h
Sprint02 480h 467h
Unfortunately we are not allowed to install any plugins, please take that into account.
