MORE INFORMATION

In the Sysmon tool, only 100 data points can be displayed in the chart view. When there are more than 100 data points, Sysmon buckets the sample data points. Each point that is displayed is represented by the minimum, average, and maximum of the bucket sample, which is represented by a vertical line.
