The Family.Show genealogy sample application includes an Age Graph that shows the number of people in the database for different age ranges.
In the sample data included for the Windsor family the number for each range was:
- 0-19: 3
- 20-39: 13
- 40-64: 17
- 65+: 16
The graph doesn’t include the additonal 32 individuals that didn’t have a birth and/or death date. I am not certain why the ages were grouped as they were.
This graph also acts as a filter for the people list. Clicking on each bar shows those individuals in that age range.
It is interesting how they chose to include both statistics and navigation in the same control.
