It would be very helpful to be able to select "Min" and "Max" as aggregation-functions on an entity, in addition to the existing "distinct count", "average" and "sum" (see second screenshot).
Right now it is possible to display the min- and max-values as a row total (see lower dataview in the first screenshot), but not if the entity is not shown by column. So the intention is to display the min-value and the max-value (as aggregation on the products) per month (see upper dataview in the first screenshot).
