BoxplotChart

Defined in: charts/boxplot.ts:23

Boxplot / box-and-whisker chart.

Two input shapes are accepted:

• Pre-computed: rows with min, q1, median, q3, max, optional outliers.
• Raw samples: mapping.y = 'samples' where each row’s value is number[].

Example

new BoxplotChart('#chart').setData([
  { label: 'A', min: 5, q1: 12, median: 18, q3: 24, max: 31 },
  { label: 'B', min: 8, q1: 14, median: 22, q3: 28, max: 36, outliers: [42] },
]);
