Summary: This line chart shows the average number of features used per person per event over time. The X-axis represents the event date. The Y-axis shows the average number of features per user, calculated by summing all feature usage counts for each event and dividing by the total number of users for that event. When filtering by gender, the calculation uses the appropriate gender count (malecount for male, femalecount for female, or totalusers when all genders are selected). This ensures users who used zero features are included in the denominator, providing an accurate average.
