Area charts add a filled region beneath the line. The fill communicates magnitude and cumulative volume, making area charts especially effective for stacked part-to-whole breakdowns over time.

​
Variants

​
Stacked

Break the measure down by a dimension and leave its placement at Stacked: the areas stack on each other. The top edge shows the cumulative total and each filled band its individual contribution. Use this for part-to-whole breakdowns over time, such as revenue by product category over months.

​
Stacked to 100%

Set the placement to Stacked to 100% and the areas fill the full height at every position, showing proportional contribution over time. Use when relative share matters more than absolute volume.

​
Overlaid

Set the placement to Overlaid and the areas share the baseline. Use only when the series are clearly separated in value and you want to compare trajectories rather than totals — with many series, the fills occlude each other.

​
Placement

Placement is set on the measure’s Break down by row in the Fields tab: Stacked, Overlaid, or Stacked to 100%. Each measure is placed independently. See Fields for the full reference. See Color & legend for palette options.

​
Area appearance

An area’s row in its axis section on the Style tab carries an Interpolation picker — Linear, Step, or Smooth — and a Trend line toggle.

​
Axis behavior

Area charts use a temporal dimension axis for time dimensions — continuous and time-aware. For non-time fields, the axis is ordinal.
