If a user wants to view a particular category by store, this can be done by clicking the stores tab (1 in Figure below). In this case the default view of the graphs and table is all the stores ranked from highest lost sales to lowest (2 in Figure below).
Using the buttons (1 in the Figure below) and the list of stores (2 in the Figure below) it is also possible to select a single or a number of stores (in this case 2) as well as to display all the individual items.
