Multiple data sources might be used for various data segmentation e.g. by projects, time frames, user groups, statuses, custom jql , etc. that might be combined in a formula. The example above shows data segmentation by time i.e. Q1 & Q2.
The picture below shows Data Source segmentation capabilities:
