Ratings over number of games instead of time

Ratings over time is a great graph, but it can be noisy because it is based by date. If I upload 5 games from a session, the averages give a strong signal. If I upload 1, it’s very weak because one game can’t represent my play that day.

You require 5 games to provide a rating. Therefore, each point on the graph needs 5 games to provide sufficient signal for a rating. You can leave the x-axis as date, but not the date the games are played, rather the date when the rating was calculated, i.e., the 5th game played.
