The yearly achievement activity graph shows how the total achievements earned by players in a game are spread out over time, divided into years. It is displayed as a relative percentage of all achievements earned.

The monthly achievement activity graph shows how the total achievements earned by players in a game are spread out over time, divided into months. It is displayed as a relative percentage of all achievements earned.

The new users over time graph shows the rate at which a game reached its current playerbase using the time when a user earned their first achievement. It is a rough approximation of lifetime sales. It is displayed as a relative percentage of all owners.

The user interaction graph shows interactivity data with up to three values. The first is "Played" which shows how many players have played the game for at least a minute. The second is "Active" which shows how many players have last played the game recently (2 weeks). The last is "Perfected" and shows how many players have completed all the achievements for this game, provided the game has achievement support (otherwise this value will not show). All three values are X% out of 100% where 100% are the total owners of the game.

The popularity over time graph shows PlayTracker's own "Popularity" metric for a game over time. "Popularity" is calculated from values like total owners, active owners, concurrent players, and more. An active owner is valued much higher than an inactive owner in "Popularity" calculation. It scales linearly - there are no diminishing returns.
