Changelog/Improvements to Distributions
Analytics·Mar 25, 2026

Improvements to Distributions

All distributions should be able to be normalized with added normalization, PDF, and CDF features to make amplitude histograms comparable and more data advanced.

Improvements to Distributions

What it is

What it is: Frequency charts, histogram charts, session length, and time-to-convert now support normalization, PDF, and CDF views. Normalization scales each series so its bars sum to 1, making groups with different sample sizes directly comparable — for example, U.S. versus Canada users no longer requires accounting for population differences before reading the chart. PDFs show the relative likelihood of values across a distribution. CDFs let you read off percentiles and range percentages, like the p95 for time to convert or the share of sessions between 3 and 10 minutes.

Where: Frequency chart, histogram chart, session length chart, time-to-convert chart

Who: All customers, including EUDC

When: GA. Available now.
