The first chart is here. Displays a score for each year based on what you rate your anime. The score is a total of the ratings from a year. It only considers ratings above a standardized score of 0.5, and it then tripled, so a show with a stdrating of 3 is worth 9 times as much as a show with a stdrating of 1. (stdrating of 3 is about equivalent to 10 and 1 is about equivalent to 6, assuming an average of 6).
