Bar charts count unique accepted problems (merged with the global problem set for rating and tags). Heatmaps use UTC calendar days. Rating squares are sums of newRating − oldRating from user.rating when System update time falls on that day. Submissions count every row from user.status (all verdicts), paginated until Codeforces has no more rows—heavy accounts can take a few seconds.
