Results limits and sorting logic in Data Tables charts

This article helps you:

  • Use the sorting logic behind Data Tables to create elegant and accurate charts

  • Understand when, why, and how Data Tables limit the amount of data you export

For more complex analyses, it's important to understand how Amplitude Analytics decides what results to display, as well as what happens when you sort on a given column.

  • If your group-by includes a large number of different property values, Amplitude Analytics displays the top 100 group-by results. With multiple top-level group-bys, the limit is 500.
  • If you're nesting group-bys, Amplitude Analytics applies the limit to each one separately. For example, if you have a top-level group-by around the city property, where the limit is 100, Amplitude Analytics only displays the top 100 group-by results. If you add a second-level group-by around the email property, a maximum of 100 emails display for each city.
  • Any metric with attribution has a limit of ten results.
  • If your Data Table includes metrics with different limits, the smallest row limit applies.
  • If your table contains metrics that aren't segmentation-based (like conversion, attribution, or session), and you're doing multiple group-bys, you may see fewer results than the limits described here might suggest. Contact your CSM or Amplitude Support if this is an issue.

Sorting logic

Once you have these results, any sorting you do applies only to them, and doesn't bring in any new results.

For example, imagine your group-by has enough different property values that Amplitude Analytics limits the results displayed to the top 100. By default, Amplitude sorts these results in descending order. If you opt to view your results in ascending order, you don't see the “bottom 100” results instead. You still see only the same top 100 results—only their sorting order has changed.

When using multiple metrics, sorting by a particular column displays data for all columns based on the values in the sorted column. For a data table with multiple segments, multiple metrics, and a period over period comparison, sorting a period-over-period column within a metric gives you a dataset based on the first segment's current period.


Limits for .CSV exports

Results exported to .CSV have row limits based on the metric type. If the data table contains multiple metrics of different kinds, the smallest row limit applies. Amplitude Analytics prunes rows exceeding the limit, and they don't appear in the exported .CSV.

  • Event segmentation metrics without attribution are limited to 10,000 rows.
  • Funnel metrics without attribution are limited to 300 rows.
  • Session metrics are limited to 100 rows.
  • Any metric with attribution is limited to ten rows.

Limits for Dashboard REST API queries

With results queried from the Dashboard REST API, event segmentation metrics are limited to 1000 rows. This is the only difference from the .CSV limits described in the previous section.

How time properties work in Data Tables

When you apply time properties as group-bys, all limits described above apply to each group of the property.


  • If you are using multiple top-level group-bys, the display limit is 500 rows.
    If, for example, you add another top-level group-by for the month property (a time-related property), and the date range includes three months (and thus, three different values for the property), up to 1500 rows (500 rows * three property values) will be displayed in your Data Table.
  • If you export a funnel metric without attribution, grouped by a non-time property, the .CSV export result limit is 300 rows.
    If, for example, you add another top-level group-by for the day property (a time property), and the date range includes seven days (and thus, seven different values for the property), up to 2100 rows (300 rows * seven property values) will be exported to your .CSV.
  • The 10,000 row limit for event segmentation metrics without attribution doesn't apply if the final group-by in the top level group includes a time property.
