# Cohort Retention ## Cohort Retention One of the classic (and harder to interpret) data visualizations of growth marketers is the cohort retention graph. Such a plot shows you the retention of a given cohort through time (reading left to right on the below chart), or of the same time period (e.g. two time periods in) across different starting cohorts (reading from top to bottom). \

Something really compelling for new users happened around Jan. 22nd, and Feb. 26th. Also, Feb. 12th cohort got re-engaged by whatever happened on Jan. 29th.

As befits a complex plot, the configuration is also slightly complex. The Activating Event is the event that definitionally marks the beginning of the user journey for the purposes of the plot (here, having done a swap). The Retaining Event is what class of event the user must have done to be considered an active user in that cohort (here, the relatively light-touch event of a page view). The period is simply the size of the time step used to define the cohort: daily, weekly, or monthly.
If the retention plot looks too small (only 3x3 say), either reduce the period to something shorter, or lengthen the date range in the upper right-hand side date picker. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
