show number of unique visitors sending an event action

[unhammer]

Say I have an event action "foo", that shows up as having 10 hits one day, but if I open the segmented visitor log I count 6 unique users. It'd be nice if there were a simple way to get that number "6" out without opening the visitor log and counting manually.

Fyi: this can be achieved with the new Custom Reports (a premium feature): https://piwik.org/docs/custom-reports/ from the marketplace: https://plugins.piwik.org/CustomReports

An alternative workaround you can do to get unique events metric in Matomo is:

• Create a segment, matching visits that triggered a specific event: https://matomo.org/docs/segmentation/
• Apply the segment.
• Open the Visitors > Overview report.
• Get the "Unique Visitors" metric. This is equivalent to the "Unique Events".

Downside is that you need to create a segment for each event you want the "unique events" metrics for.
