1) New Features

Chart Transitions

You can now switch the chart type you are viewing by clicking the chart type name and selecting a different chart type all without navigating away from your chart. In addition, you have the option to preserve all the events and/or segments you have already added to your current chart. This allows you to quickly switch between different types of analyses without having to rebuild from scratch each time!

In-Line Behavioral Cohorts

(Enterprise Only) You can now create simple Behavioral Cohorts in-line directly within the right module of the chart control panel. This will allow you to create a cohort in the context of a chart without having to navigate away into the Behavioral Cohorts tab. You can do this by selecting the “+perform” button. Similar to chart transitions, this helps streamline your workflow and minimizes the need to navigate away from your current view while analyzing your data.

Percentiles in Formulas

We have introduced a new function of PERCENTILE in our Custom Formulas feature. This will return the inputted percentile of the event selected and will only work if you are grouping by a numerical property on the event. For example, if you wanted to display the 50th percentile for the ‘Duration’ of all ‘Play Song or Video’ events, you would do PERCENTILE(A, 0.50). For more information on our Custom Formulas feature, see here.

Propose Charts to Dashboards

(Enterprise Only) Previously, charts could only be added to a dashboard by the dashboard owner. Now, other users in your organization can propose chart additions to dashboards they do not own. The dashboard owner will receive a notification in the Notification Center and can accept or reject the suggestion.

2) Feature Improvements

Auto updated top values

When you create a chart with multiple values/events, you now have the option to always display all top N values on a chart. For example, if you want to always display the top 10 cities with the most active users, then you can select top 10 in the breakdown data table below your chart. The top 10 values may then change if your user base grows in new cities. A chart with top N values will have a breakdown data table with purple checkboxes. For more information on this improvement, see here.

Custom Events: View definitions in charts

Custom events is a feature that’s widely used in Amplitude. We have made it even easier to view the custom event definition while in a chart so you no longer have to navigate to the Settings page for more information. Now, you can view the definition of a custom event directly in the chart control panel!

Behavioral Cohorts: View definitions in charts

(Enterprise Only) Similarly, you can now view the definition for a Behavioral Cohort directly in the current chart you are working on!

Event Segmentation: New group by visualization

The previous group by visualizations available were another area for improvement. Oftentimes, when multiple group by’s are applied to a chart, the resulting view was very confusing and difficult to digest. As a result, we’ve added a new group by visualization to our Event Segmentation chart type that makes it easier to analyze data when there are several group by’s on a chart. Read more about this new visualization here!

Event Segmentation: Tabs in bottom module

We have also redesigned the bottom module in our Event Segmentation chart so that each metric you can select is in a separate tab instead of in one dropdown menu. This makes it easier to see all available options. To read more about the metrics in our Event Segmentation chart, see here.

Retention Analysis: Multiple return events

You can now select up to 2 return events in your Retention Analysis charts. This allows you to compare 2 return events side-by-side to see the retention rates without having to create 2 separate charts. For more information on this feature, see here.

3) Resources
