Life Line Chart View is an interactive Charts Charts category view addon which shows individuals as lines in an ancestor or descendant chart. The length and position of the line depends on the actual life span and the marriages. The pedigree/ancestor collapse is handled. Labels for birth / names, death, and marriages can be added.

The active person on the person tab is starting point in both charts. Birth/christening/baptism, death/burial, and marriage dates need to be available to properly draw this chart. If they are incomplete reasonable guess values are chosen if possible. If not, then these individuals are not shown


Two new chart icons will appear in the Charts Charts category view tool bar if the addon was loaded successfully and the prerequisites have been installed: LifeLineChartView default Toolbar-Icons-51.png
