  • Use events and properties to create an Event Segmentation analysis

For most users, Event Segmentation is the foundational Amplitude chart. It shows what your users are doing in your product. With the Event Segmentation chart, you can build analyses that:

  • Measure the top events performed over a selected time period
  • Analyze how often events are triggered
  • Determine the count of unique users triggering events in your product
  • Clarify which users tend to trigger certain events

Like most Amplitude charts, Event Segmentation charts are built by combining events and event properties with user segments. These can be simple—like, for example, counting the number of users firing a specific event—or they can be intricate formulas of events. 

This article will outline the steps required to build a segmentation analysis in Amplitude.

Feature availability

This feature is available to users on all Amplitude plans. See our pricing page for more details.

Before you begin

If you haven’t already read up on the basics of building charts in Amplitude, you should do so before proceeding.

See this article to read about selecting the best measurement for your Event Segmentation chart.

Set up an event segmentation analysis

An event segmentation analysis shows what different groups of users are doing in your product. You’ll need to tell Amplitude what events you're interested in, and which users it should include in the analysis.


You can include both active and inactive events in your segmentation analyses, but most customers find their Amplitude charts are more insightful when they focus on active events.

To build an Event Segmentation chart, follow these steps:

  1. In the Events Module, select the starting event or metric. You can choose a specific event that is instrumented in Amplitude, or you can tell Amplitude to consider any event as the starting event for this analysis, by selecting Any Event from the list of available events.

    You can also create an in-line custom event or create a new metric at this point, if you need to.

  2. If desired, add properties to your starting event by clicking on + Filter by, selecting the property name, and specifying the property value you’re interested in.

  3. Next, select another event to include, if desired. You can choose up to ten, and you can add properties to these events as well.

  4. In the Measured As Module, specify how you'd like to measure your results. Unique users and event totals are the most commonly-used, but you have several other options to select from. For details, see the Choose the right measurement section below.

  5. In the Segmentation Module, identify the user segment you want to include in this analysis. You can import a previously-saved segment by clicking Saved and selecting the one you want from the list. Otherwise, Amplitude begins from the assumption that your analysis will target all users.


The user segment you select will apply to all selected events.

  1. If you do not want to import a previously-saved user segment, you can start building your own by adding properties. To do so, click + Filter by, choose the property you want to include, and specify the property value you’re interested in.

  2. You can narrow your focus even further by telling Amplitude you only want to include users who have already performed certain actions. To do so, click + Performed, then choose the event you’re interested in.

  3. If desired, add another user segment by clicking + Add Segment, and repeating steps 6 and 7.


You can break out your starting event by user properties by clicking Group segment by in the Segmentation Module, if desired. For example, if you wanted to group users by the cities they were in when they triggered the starting event, you would select City from the property list. Amplitude will then break out the segmentation analysis on a city-by-city basis.

In the chart area, you should now see your Event Segmentation chart, along with a tabular view of your results.
