Name of affected component: Core Reporting API
Name of related library and version, if applicable (e.g. Java, Python,
HTTP, Objective-C, etc.): Java
Issue summary:
We are using analytics reporting API to retrieve the data for different metrics
and dimensions. We then verify the data against analytics reports/graphs.
The instance in which we are facing the issue is, we are fetching the data for
ga:users metric with ga:source dimension. i.e. we are fetching the data for
users with different sources. We store day by day data and calculate the
aggregate for the whole month.
We then compare that aggregate (sum) for different sources with google report
(via custom reports) but the values don't match. We tried comparing day by day
data for particular source (e.g. google) and it matched. However, the aggregate
values are different.
On further investigation, we found that the values displayed below the
reporting graph (on analytics page) don't match the sum of all the values. E.g.
If we query the data for December 1st to 10th, 10 points are displayed in the
line graph and a value (presumably the sum) gets displayed below the graph.
When we add all those 10 values, the number is different (and in most of the
cases, greater) than the number displayed below graph.
Steps to reproduce issue:
1. Go to 'Customisation', click on 'New Report'.
2. Select 'Users' as metric, 'Source' as dimension and 'google' as filter.
Select the date range from 1st December to 31st December (or any range).
3. A graph along with the aggregated value below will be displayed. Sum up all
the values of graph and compare that against the aggregated value. Both values
will be different.
Expected output:
What do you expect to see after performing the above steps?
Both the values (i.e. sum of all graph values and the number displayed below)
should be same.
Actual results:
What do you actually see after performing the above steps?
Both the values (i.e. sum of all graph values and the number displayed below)
are different.
Notes:
Provide any additional information which might be useful here. Feel free to
attach screenshots or sample code which demonstrates the issue being
described.
We have attached the screen shot herewith. The sum of all the graph values is
112969 whereas the value displayed below graph is 97439.
