The columns in the browser have the ability to be filtered by plan type to get a list of which metrics are included with which plans.
If you right click on a column, there will be a filter option which can be selected as seen in the example below. If a metrics says Essentials, that means it is available in the Essentials, Premium and Premium Plus plans. Similarly a metric that is Premium would be available in the Premium and Premium Plus plans, but not the Essentials plan.
To see all metrics available with the Premium plan for example, you would want to check both the Essentials and Premium boxes, but leave the Premium Plus box unchecked. To see which statistics you get in Premium above and beyond Essentials, you would check just the Premium box.
