Add Option to View the Fan Chart by Birth Year Color-Coded in Half Century Increments

ajellis

Previously, there was an option to view the fan chart by birth year which was color-coded by century. I'm not seeing that now but would like to see this option again but color-coded by half century (ie born between 1700-1750, 1750-1800 and so on). This would help when I'm working on various projects. Thanks!
