I am tracking a number of events on a website and am trying to extract some analytics data via the api. The problem I have found can be boiled down to this scenario. If I want to know how many unique events have happened per day, I can run a query such as:
?start-date=2016-02-19&end-date=2016-02-24&metrics=ga%3AuniqueEvents&dimensions=ga%3Adate
which will give me table of the number of unique events per day from Feb 19th to Feb 24th. In my specific example, I will have a row that say I had 12914 unique events on Feb 22nd.
If I now change the time period for the query to something like this:
?start-date=2016-02-01&end-date=2016-05-01&metrics=ga%3AuniqueEvents&dimensions=ga%3Adate
I will basically get the same table, only from Feb 1st to Mai 1st. Was suprises me though is, that now the column for Feb 22nd reads 12966 events, while my assumption would be, that this number should actually stay the same.
Is there something I'm missing here? In which scenario would these numbers make sense? Thanks for your help!
