If you have several stores linked to your back office user, you can select the data of the store/s you wish to display on your dashboard using the store picker.
By default, all stores are selected. To change the selection, simply click/unclick the stores in the store picker. If you want to select/deselect all stores you just need to click on "all stores".
In this way, the turnover, the number of customers, the average basket and the graph on your dashboard will be determined according to the selected stores.
