This data source captures the development of the size of a selected segment over time.
For each date bucket, members who were part of the segment at the end of the date bucket are considered for the count.
For example, if a member met the segment criteria on the 2nd of the month and left the segment on the 27th, using a date bucket of the month, the member would not be counted in as they were not part of the segment at the end of the bucket.
Using higher granularity of data buckets (for example, weeks or days) or selecting subsets of date buckets (1-27 of the month in the previous example) would reveal the member being part of the segment as they would be counted in.
