Amplitude's Event Segmentation chart helps you understand what specific groups of users are doing in your product. For example, in an event segmentation analysis, you can:
- Identify the top events fired over a selected time period
- Compare event totals to each other
- See which users fire certain events
Analyzing your event segmentation data takes place in the chart area, in the right-hand side of your screen. This is where your events, metrics, and user segments come together to give you a visualization of user behavior.
Before you begin
If you haven't done so already, you'll want to familiarize yourself with the basics of building charts in Amplitude , as well as how to create an Event Segmentation chart. You can also see FAQs about the Event Segmentation chart here.
Interpret your Event Segmentation chart
Event Segmentation is Amplitude's most commonly-used chart. It's simple enough to create a useful analysis quickly, even as a brand-new Amplitude user. The rest of this article will explore these features and explain how you can best put it to use to generate insights on user behavior.
Breakdown table
Below the chart, you'll see a table of the data included in your chart. Within the data table, you can:
- Update the chart display, by selecting or deselecting rows in the table
- Download the data table, by clicking the "Export CSV" button
- Modify the summary column based on Row Average, Median, Change, or Sum(Only available for Event Totals, Properties, and Formulas)
- Sort by columns, by clicking the column name (i.e. Sum, May 21)
- Specify the number of series you'd like the table to display (this selection will persist through sorting, saving, and refreshing, as well as to any dashboards that include your chart)
By default, Amplitude will include all top values or events in this table, which will update automatically when Amplitude receives new top values or events. You can turn this off by first deselecting the segments and then explicitly selecting the values and events you want to keep.
Change your chart view
Whichever metric you choose, you’ll have several options when it comes to how you want your results displayed on the chart.
The default setting is a basic line chart. These are useful for looking at the trend of one event for one user category over time.
Stacked area charts are useful when you’re looking at data that breaks down into discrete buckets, like when you’re analyzing multiple events.
Bar charts are good for situations when you want to show a distribution of data points, or compare metric values across different segments of your data. Bar charts make it easy to see which values are highest or most common, and how specific groups compare against the rest.
A stacked bar chart will show how broad categories or buckets are divided into smaller ones, as well as the relationship each of those smaller parts has to the overall total.
If your analysis uses multiple "group by" conditions, the resulting visualization might turn out confusing and hard to interpret. While it’s not specifically a chart type, the group by visualization will clarify your data in these circumstances.
For example, here the control panel groups the 'Play Song or Video' event by genre type, as well as by country and platform.
Instead of a temporal or “bucket-based” chart, the horizontal bar chart generates a table view, breaking out the genre type, country and platform (in other words, the group-by conditions that were applied to this analysis) into separate columns. This makes it easier to digest and cross-reference the data. In this example, users in the United States who played pop songs were more likely to be doing so from a web platform—but not by much:
For more information on the syntax and limitations of group by conditions, see our Help Center article here.
Switch between absolute totals and relative percentages
When using stacked area charts and stacked bar charts, you can choose to view your analysis in terms of relative percentages instead of absolute totals.
# Absolute will display the overall user volume, whereas % Relative gives you the series value divided by the sum of all the series values.
