The powerful Row Evolution feature shows you the current & past metric data for any row in any report. You can view how metrics for visits that use firefox or visits that came from Google or almost anything else change over time. Additionally, you can compare these trends with the trends behind other rows to gain even more insights (e.g. comparing the use of two different keywords over time).

Row evolution can show you trends within reports not just with regard to a couple metrics, and is thus unique within all of Piwik. Only through this feature can you see how visits to specific pages change over time or how visits with a specific browser change over time.
You can use row evolution to gain a nuanced understanding of how your web traffic changes and will change, and with the combination of another powerful feature, Annotations, you can record these insights for later recollection.

The popup will close and you will now be able to pick another row to compare with. To pick a row, click the row evolution icon on the other row:
The new popup will display row evolution for both rows using the ‘visits’ metric by default:
You can switch metrics by selecting another metric in the select box at the bottom of the page:
