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 { RidgelineChart } from '@silverpoint/react/ridgeline-chart';`
Vue	`import { SpRidgelineChart } from '@silverpoint/vue/ridgeline-chart';`
Angular	`import { SpRidgelineChart } from '@silverpoint/angular/ridgeline-chart'; // <sp-ridgeline-chart>`
Reflex	`from reflex_silverpoint_react import ridgeline_chart`

Props

The props RidgelineChart 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>`	The group of an observation; one ridge per group.
`bandwidth`	`bandwidth`	`bandwidth`	`number`	Kernel bandwidth in data units, shared by every group; Silverman's rule by default.
`overlap`	`overlap`	`overlap`	`number`	How far a ridge reaches into the one behind it, 0-1; 0.5 by default.

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.
