Generations view
How generations are assigned
TreeLine assigns generations by starting from the earliest-born person
in the tree and working outward:
- Children are one generation higher than their parent
- Parents are one generation lower than their child
- Spouses share the same generation
Generation numbers are normalised so the earliest generation is always 1.
Reading the view
Each bar is coloured by its generation, with a numbered badge showing
the generation. The legend on the right lists every generation with its
colour, and clicking a generation in the legend selects all people in
that generation.
Adjacent generations use contrasting colours (warm then cool) so
neighbouring rows are always visually distinct.
