Once you have selected one view in your dashboard - we call this a tab, it is visible in the menu to the left. You can add several tabs in your dashboard, to show multiple different breakdowns and visualizations of your data.

In the example below we have two tabs 'Deepdive traffic' and 'Platform and placement engagement':

If you have multiple platforms selected in your dashboard, you can easily set up a tab that only displays results from one platform, by selecting the platform on a tab level:

By doing this, you can set up a tab with the combined performance, which allows you to get an overview across channels, and one tab for each platform, which allows you to dig deeper into the performance of each channel - all in the same dashboard.
