sunburst

The sunburst renders a hierarchy as concentric rings, from the centre hole outward, one ring per level. It accepts a native children hierarchy or an existing drilldown config (adapter). See the sunburst chart guide for a walkthrough.

Sets the left offset of the whole sunburst area.

Sets the top offset of the whole sunburst area.

A custom angle from which the rings should start. Combine with endAngle for a semi-circle sunburst.

A custom angle at which the rings should end.

Radius of the centre hole, as a percentage of the maximum radius (or a pixel value), like a donut's size. Set '0%' for a solid nested pie.

Rounds the corners of each arc (in px), with the same semantics as plotOptions.pie.borderRadius. Defaults to 0 (sharp corners).

Gap between adjacent arcs (in px), with the same semantics as plotOptions.pie.spacing.

How a branch that bottoms out before the deepest level is drawn. 'extend' (default) stretches the leaf arc out to the rim so the ring stays solid; 'stop' leaves the outer rings empty behind it.

How a parent's wedge is split among its children. 'normalize' (default) divides by each child's share of its siblings, which is safe for any data; 'strict' expects children to sum to their parent's value.

How much lighter each depth level is tinted than its parent colour (0 keeps the parent colour, 1 is white). A per-node color overrides the tint for that arc and its subtree.

Click a wedge to zoom into that branch: its subtree fills the chart and a breadcrumb walks back. Click the focused inner ring to zoom out. Set false to keep the chart static.

Whether to render the label on each arc.

Hide the label on any arc narrower than this angle (in degrees), so tiny wedges do not overflow with text.

Font size of the arc labels.

Font family of the arc labels.

Font weight of the arc labels.

Array of colors for the arc labels.
