Module boxplot 

Box plot — quartiles + whiskers + outliers, one box per named group. The data→geometry math (Quartiles::from_sorted / Quartiles::compute) is a pure function with its own tests; BoxPlotView is the themeable [Facet] that paints it and emits the underlying data as CSV/JSON.

Structs

BoxPlotState

Persistent, observable interaction state (FC-3). The box plot’s only mutable state is which group box the pointer last hovered — an index into BoxPlotView::summaries. Serialized so it round-trips headlessly.

BoxPlotView

A box plot: named groups of raw samples.

Quartiles

Five-number summary + the 1.5·IQR whisker fences and the points beyond them.

Enums

BoxPlotEffect

FC-8: the box plot does no I/O — an uninhabited effect.

BoxPlotMsg

FC-2 input surface. The box plot accepts one kind of input: the hovered box changing (hit-tested purely in BoxPlotView::render, applied in BoxPlotView::update).

Functions

percentile_sorted

Linear-interpolated percentile of a sorted slice. p ∈ 0..=1.
