The Layout Editor is a data aware graphical editor. This is obvious for graphs, whose appearance change with updates in your gating.  It similarly applies to other items that can be created in the Layout Editor, such as statistics, equations, plates, and tables.

Editing Statistics in the LayoutTo display a statistic in a layout, drag and drop it, just like dragging populations.

Tables in Layouts: Tables generated in the Table Editor can be imported into your layouts and will update dynamically with your graphs.  In the Table Editor, click the Batch to Current Layout icon.

Population Specific Tables in the Layout Editor: Create tables of statistics for a single sample’s entire hierarchy.
Layout Editor EquationsThe Layout Editor allows you to create equations in the text editor using FJML.
