Similar to the possibility google analytics offers it would be great, if piwik would allow to compare segments. I searched for a similar issue but couldn't find it. So hopefully this isn't a duplicate.
@DaSchTour absolutely, ability to compare the same data set for 2 segments, in the same data table, would be awesome!
it's related / similar to the ability to compare two different date perids for the same report(s) in #5711 as in google analytics and other advanced analytics tools
Related to comparing dates as well (since both would use same mechanism) https://github.com/piwik/piwik/issues/5711
Unassigning myself for now as I'm not sure when I find time to work on it again. Started work on it here: https://github.com/matomo-org/matomo/compare/5711
Done so far:
date1=&period1=for date comparison, as well as
&segment1=...&segment2=&segment3=&segment4=for segment comparison. both can be used together
To be done:
