  Pattern-Analysis Plot Sheet
  6-73. A pattern-analysis plot sheet focuses on the time and date of each serious incident that occurs
  within the AO. The rings show days of the month; the segments show the hours of the day. As shown in
  the plot sheet's legend, the chart shows the actual events; it identifies each by using an alphanumeric
  designation that directly corresponds to the legend used on the coordinates register. The legend icons can
  be changed to show other types of incidents such as vehicle-borne IEDs (VBIEDs), command-wired IEDs
  (CWIEDs), and radio-controlled IEDs (RCIEDs). Figure 6-10 shows an example pattern-analysis plot
  sheet.
  Note: List daily entry number on calendar. In journal, cross-reference each incident to the
  incident overlay.
