Import

Each chart has its own subpath, so a bundle only carries the charts it uses. Every adapter also exports every chart from its barrel.

Framework	Import
React	`import { EcdfChart } from '@silverpoint/react/ecdf-chart';`
Vue	`import { SpEcdfChart } from '@silverpoint/vue/ecdf-chart';`
Angular	`import { SpEcdfChart } from '@silverpoint/angular/ecdf-chart'; // <sp-ecdf-chart>`
Reflex	`from reflex_silverpoint_react import ecdf_chart`

Props

The props EcdfChart adds to the ones every chart takes. Accessor props (…Key, keys, names) name fields of your rows and are ignored without data.

React / Angular	Vue	Reflex	Type	Description
`valueKey`	`value-key`	`value_key`	`Accessor<number \| null \| undefined>`	—
`groupKey`	`group-key`	`group_key`	`Accessor<string \| null \| undefined>`	Two groups at most are drawn.
`markers`	`markers`	`markers`	`readonly number[]`	Quantiles, in 0-1, drawn as rules.

Common props

Every chart also takes these. Framework conventions: camelCase in React and Angular, kebab-case in Vue templates, snake_case in Reflex. Read more about them.

Show the 22 common props

React / Angular	Vue	Reflex	Type	Description
`data`	`data`	`data`	`readonly Datum[]`	Rows to draw. If omitted, the demo dataset is rendered (REQ-093) and the accessor props (`…_key`, `keys`, `names`) are ignored.

`width`	`width`	`width`	`number`	—
`chrome`	`chrome`	`chrome`	`'card' \| 'bare'`	`card` draws the full frame; `bare` only the drawing area (REQ-095).
