Statistics can be added to populations in two ways: (1) by selecting one or more populations and clicking on the "Statistic" function button in the workspace window; this adds statistics to the selected populations, or (2) by viewing a population in a graph window and clicking on the "Statistic" button in that window. Both ways brings up the Statistics Dialog window.

Statistics are displayed in the workspace window whenever they are calculated. If a statistic node in the workspace does not show its value, then you may request it to be computed. Select any node which has that statistic as a descendant (i.e., the population to which it is attached, or any parent of that population), and select "recompute" from the FlowJo menus. All statistics can be hidden from view by selecting the Workspace menu item (show them by selecting the same menu item again).

Statistics can be conveniently organized and exported by the table editor. Statistics nodes can be dragged to the table definition; when the table is computed, then all statistic nodes will be updated and computed.

In addition, you can drag statistics into the layout editor.  This will create a text box containing the statistic description and the value; it will be updated whenever the statistic is modified (i.e., it is "live").
