The ability to add filter controls to your charts in Data Studio is one of its coolest features. It would be even cooler if you could load a report with a filter control and a particular option pre selected. As far as I can tell, this is not currently possible, but here is a work around you might useful.
Check out a simple example here (via the new embed function which I should probably write another blog about):
It seems like there are new things being added every week to Data Studio so this may be supported soon, but in the mean time here is a quick trick you can use to emulate the filter controls and load a page with an option already selected.
As per the above example let's say you have a chart and you want the user to be able to break it down by device category but on page load you would like to display only mobile traffic.
What we can do is create duplicate report pages, apply filters to each of them and then make a faux filter by creating links between the different pages.
Start by making your report, for our demo we've just got one chart showing traffic sources with the most sessions. Once you're done, right click the canvas and select current page settings.
Add in the relevant filter value that you want to appear on page load. For our report we've filtered to only include mobile traffic.
Now duplicate that page but go in to the page settings on the second page and swap the filter out for your next filter value i.e. desktop.
We should now have a report with two pages, one with a mobile filter and one with a desktop.
Then what we need to do is create a link between the two different pages, that we will use for our "filter". Click the view button in the top right corner and grab the url for the page you're on. Then move to the other page using the Data Studio navigation and grab the url for that page. They will look something like this:
Click back in to edit your report and select insert > text. Drag out your text box and type in the name of the other variant than the page you're on e.g. "Desktop".
Now highlight your text and in the text properties panel on the right hand side click the little hyper link icon.
In the link text field past in the url for your other page and deselect the open link in the new tab option.
If you view your report now you should have your table with the link sitting above it. Clicking this link will load the other page of the report.
The other page wont have this link so you will just need to create a new link on this page and link it back to the other page.
That is all there is to it!
This likely won't be appropriate for situations where you have a long list of filter options, but for some use cases it may come in handy and it does allow you to create your own custom styles for the filters like the tabs I've used in my example.
