Area Chart - Custral Docs

An area chart, the same series, filled to show volume.

When to use

Area charts shine when you want to show how a value (or a few values) accumulates or evolves over time, and you want the magnitude (not just the trend) to feel visceral. The shaded area communicates volume.

Required data shape

X axis: a date or ordered numeric property.
Y axis: a numeric or aggregated property.
Group (optional): a select / status property; each group gets its own stacked layer.

Configuration

Setting	What it does
X-axis	The date or ordered property plotted along the horizontal axis.
Y-axis	The numeric value (or aggregation) the shaded area represents.
Group by	An optional property whose values become separate stacked layers.
Stacking	How layers stack: default (overlaid), stacked, or 100% (percent of total).

Limitations

Stacking with more than ~6 groups becomes unreadable. Use a Top-N filter.
Sparse data series produce visual gaps; switch to a Line chart if you need precise endpoints.
