Hi @sebastiane27965 ,
Not sure if occurrences is sufficient for the use you are mentioning unless you are sure to set the evar to expire on each hit.
As an alternative, to reduce evars and allow cleaner reporting, have you considered just one evar for direction and then an event for when someone has swiped in the app? Then it would look like dragging a single evar onto a table with a breakdown of "Left" vs "Right" and a specifically named metric just for app swipes.
In fact, you could avoid adding any evars by sticking the direction into another evar with information on the page/panel being viewed. That is, if they swiped right from page 3 to page 2, a developer could put into a pagename variable the value of "Page2<delimiter>R", or if someone swiped left from page 4 to page 5 "Page5<delimiter>L". Then using classifications on this variable, you could break it apart at the delimiter for normal reporting. So the left side of the delimiter can be grouped into a classified pagename and the right can be classified into a swipe direction variable.
