@mk7s/holochart-traces-stats

The statistical trace types of Holochart: histogram, histogram2d, histogram2dcontour, box, violin, splom, parcoords and parcats. Part of Holochart, declarative GPU charts on three.js.

Alpha. Released as 0.1.0-alpha on the npm alpha tag; APIs can change between 0.x releases. Most apps should install the full bundle, @mk7s/holochart, which includes this package.

Install

pnpm add @mk7s/holochart-traces-stats@alpha three

three is a peer dependency, so your app and Holochart share one copy. ESM-only; Node 22 and newer can also require() it.

What it exports

• statsTraces: every trace module below, to register at once
• Trace modules: histogram, histogram2d, histogram2dcontour, box, violin, splom, parcoords, parcats
• Attribute schemas (experimental): histogramAttributes, boxAttributes, violinAttributes, and so on
• strip: builds a strip-plot figure (jittered points per category) from a table
• Grid and contouring helpers that @mk7s/holochart-traces-sci builds on. These are tagged @internal: not API, and not exported by @mk7s/holochart.

Usage

import { createChart, register } from '@mk7s/holochart-runtime';
import { builtinComponents } from '@mk7s/holochart-components';
import { statsTraces } from '@mk7s/holochart-traces-stats';

register(...statsTraces, ...builtinComponents);

createChart(el, { data: [{ type: 'histogram', x: [1, 2, 2, 3, 3, 3, 4] }] });
