Setting the area display mode

For an Areas visual with a field on the Colors shelf, the Display areas unstacked setting controls how the series appear.

Checkbox cleared (default):
Display areas are stacked on top of one another. The Y-axis shows their cumulative total, helping you see how each series contributes to the whole.
Checkbox selected:
Display areas are unstacked. Each area starts from the same zero baseline and overlaps other areas with a semi-transparent fill. The Y-axis and tooltips show each series’ individual values, helping you compare values and trends on the same scale.

To enable unstacked mode, open Settings > > Marks and select Display areas unstacked in the Visual Builder. Clear the checkbox to return to the stacked display.
