Graph reports are reports with the ability to optionally display live controls to let users navigate on the different time periods and let them see their old activity (you can disable the live controls to make them display only the time period you want).

The graph reports shortcodes are:
[gamipress_frontend_reports_points_graph]
[gamipress_frontend_reports_points_types_graph]
[gamipress_frontend_reports_achievement_types_graph]
[gamipress_frontend_reports_rank_types_graph]
