Ya, GameAnalytics allows you to add a “filter” to any metric they track.
Here’s an example screenshot of their DAU chart…
and here’s an example of their DAU filtered by what they call “Acquisition Site” which relates to the Application.absoluteUrl from Unity WebPlayer…
it might be difficult to read, but it changes the x-axis measurement to be broken down by Site.
and the green buttons allow you to change how the data is viewed… Here is the same data in a bar graph.
By default all of their graphs show a comparison period (you can see it at the top left corner where it lists two dates). The dark blue data in all these graphs is the top date range (in this case Mar 9 - Apr 8, 2015) and the light blue bar is the comparison period (which is customizable but defaults to 30 days in the past) shown as Feb 2 - Mar 4, 2015.
This is what allows them to show you month to month a change up or down across whatever comparison period you set.
You can add more metrics to each chart like Unity Analytics already has, but these are the default supplied ones and they are extremely intuitive to navigate and use.
Now my gripe with GameAnalytics is in their size as a company, level of support/service and some technical irregularities/anomolies with their data processing. Their SDK technically is still a beta version (currently 0.6.9) and any events sent to their api before a NewUser event which could be sent at a later time during session, tracks all user related data as “null” as you can see in my screenshots above. Once those users send a NewUser event, any future events will have the correct data applied to them, but their system doesn’t retroactively go back to any events from “null” and fix their data, so that data is essentially still recorded, but unclear as to the meaning of it to a business.
TLDR; Hopefully this helps, like i said, I like the tools that GameAnalytics is using, they are great for a small studio, but they are a small company without the resources of Unity to make something really solid with a great level of support as a professional service.
