From the toolbar you can drag & drop dimensions on any of the pivot areas
The combination of filter, column and row dimension drives the calculation of the selected aggregation.
Aggregations can be dragged into the Measures box.
By clicking on the small '>' on the left side of the dimension, a drop down will show listing
all individual values of the dimension. Toggle each of the checkboxes to select all relevant
values. Press OK to confirm your selection
It is possible to hide the toolbar by hitting the collapse button (or by resizing)
