# Display subject count bar charts on average time trend plots

Use this option to add a bar chart showing subject count by treatment group to the X axis of the average time trend plot. This option is selected by default.

Interpreting average time trend plots across visits can be misleading without further information about the subjects contributing to that average. For example, suppose that very sick patients begin dropping out over time so that the trends shown near the later visits of the trial reflect a much smaller subset of subjects. To aid in visually understanding the trends in findings test measurements and fluctuations or anomalies in the trend pattern, use this option to include a bar chart of the count of subjects that contribute to the mean line trends.
