The Statistics Board is a graph of the number of events of a certain type for a specified timeframe. The type of events and amount of time between the points of the graph are configured in the board settings (see Configuring a Statistics Board).
The points of the graph change over time and depend on the current time and interval specified in the settings.
The points are calculated every minute/hour/day/etc. based on the selected unit of measurement (if the interval is specified in minutes, then every minute; if specified in hours, then every hour, and so forth) and is performed as follows:
- The current time (last point on the graph) is rounded to the nearest whole unit of time (if the interval in the settings is specified in minutes, then the nearest whole minute; if specified in hours, then the nearest whole hour, and so forth).
- This rounded time is used as the next-to-last point.
- The formula for the other points is as follows: the adjacent point to the right, minus the interval of time specified in the settings.
For example, the interval is set to 10 minutes on this sample graph here. The current time (1:07:33 p.m.) is the last point on the graph, so after rounding this to the next whole minute we get the value for the next-to-last point: 1:07:00 p.m. Correspondingly, the points before it are 12:57:00 p.m., 12:47:00 p.m., etc.
When the current time becomes 1:08:00 p.m., the points will be updated to 12:58:00 p.m., 12:48:00 p.m., etc.
The graph displays the current number of events. The number of events is recalculated every minute and does not depend on the interval chosen.
For example, for this graph with a time interval of 2 hours and a current time of 1:48:23 p.m., the current number of events equals 413, for the period from 11:48:00 a.m. to 1:48:00 p.m.

Clicking anywhere on the graph jumps to the nearest point and the relevant value is indicated.
