The Drop Zones panel features several different types of drop zones; each zone drives a corresponding component in the visualization, and vice versa, The selected visualization determines which drop zones will appear. For example, the grid visualization enables the Rows and Columns zones, while Cartesian charts enable the Category zone.

Deriving the Chips in the Drop Zone
The orange and blue "chips" in the Tabulate drop zones are pivotal elements - allowing you to position different parts of the data set into different elements of the chosen visual - like categories, series (or color), labels, tooltips and the values themselves.
- The value items - or orange chips - are derived by looking at elements in the selected visual range and heuristically determining the values of the selection. Usually these are the columns in the area when its a classic grid (see example above)
- The categorical or attribute items - or blue chips - are derived by looking at the elements in the selected visual range and heuristically determining the non-value elements of the selection. Usually these are the rows in the area when its a classic grid (see example above)
The chips are then presented to users in the drop zones based on these derivations - and are automatically placed in drop zones (right side of image above). You can switch these around to adjust the visual or use the "Unused" drop zone item (specific to Tabulate visuals) to discard selections from your visual.
