Pie Chart - Custral Docs

A pie chart broken down by segment.

When to use

Pie charts answer “what share of the total is X?”. The center is filled (no donut). Pick Pie over Donut when you don’t need the center for a headline metric.

Required data shape

Same as Donut. A categorical group property and an optional aggregated value.

Configuration

Setting	What it does
Group by	The property whose values become the pie slices.
Value	The numeric value aggregated per slice. Defaults to a record count.
Aggregation	How values roll up: Count, Sum, or Average.

Limitations

Five or fewer categories.
Like Donut, pies are bad at communicating precise differences. For exact comparison, use Bar.
