Hi @RonGros , is your data denormalized? If it is denormalized, I.E each row represents one time one person watched one movie, you can easily bucket by date in Lens, then unique count of name would be the number of people who saw a movie in that time period. If you're calculating an average, you'd need to calculate it over multiple buckets, whereas a graph would show a value per bucket, so I'm not exactly sure what the average you're looking for is.
