Add comparison charts to your reports

You can use a comparison chart to compare a single metric across all your apps, ad units, ad formats, or the countries your users are in.

Each comparison chart can display up to six lines. The first five lines represent the top 5 items within the selected comparison dimension. The sixth line represents the total of all other items within the dimension.

The meaning of each line is displayed in the legend below the chart. Hover over the lines to view the values they represent.
