PcPlot

Represents a viewer. See also https://datagrok.ai/help/develop/how-to/manipulate-viewers

See

Use Viewer to control the viewers. To develop a custom viewer, JsViewer.

Example

let view = grok.shell.addTableView(grok.data.demo.demog());
view.scatterPlot({
    x: 'height',
    y: 'weight',
    size: 'age',
    color: 'race',
  });

Methods

_notifyPropertyChange()

protected _notifyPropertyChange(p): void

Defined in: js-api/src/widgets/base.ts:351

Notifies the property tier. Called from both the addProperty setter (overrides that skip super would otherwise lose props.x = writes) and onPropertyChanged (direct calls); the double notify collapses into one microtask refresh.

Parameters

Parameter	Type
`p`	`Property` \| `null`

Returns

void

Inherited from

Viewer._notifyPropertyChange

_ownPropertyChanges()

protected _ownPropertyChanges(): ObservableLike<PropertyChange>

Defined in: js-api/src/widgets/base.ts:356

Returns

ObservableLike<PropertyChange>

Inherited from

Viewer._ownPropertyChanges

_scopeMinted()

protected _scopeMinted(_scope): void

Defined in: js-api/src/widgets/base.ts:320

First-mint hook: a platform descendant wires its lifecycle here. Never fired for a scope provided to init — that path runs inside the constructor chain.

Parameters

Parameter	Type
`_scope`	`Scope`

Returns

void

Inherited from

Viewer._scopeMinted

_wireDartLifecycle()

protected _wireDartLifecycle(): void

Defined in: js-api/src/widgets/base.ts:336

Dart-owned lifecycle: the platform kill disposes the scope, and disposing the scope kills the widget through the kill-walk.

Returns

void

Inherited from

Viewer._wireDartLifecycle

_wireJsLifecycle()

protected _wireJsLifecycle(): void

Defined in: js-api/src/widgets/base.ts:327

JS-owned lifecycle: disposing the scope detaches the widget, and vice versa.

Returns

void

Inherited from

Viewer._wireJsLifecycle

_wireLifecycle()

protected _wireLifecycle(): void

Defined in: js-api/src/viewer.ts:226

Returns

void

Inherited from

Defined in: js-api/src/widgets/base.ts:261

Parameters

Parameter	Type	Description

Returns

Widget

Inherited from

Viewer.apply

bindProps()

bindProps(): BindProp[]

Defined in: js-api/src/viewer.ts:246

The signal-backed subset of the meta props — what a binding picker offers on a named node — plus, under propertyTier, every declared property. Allocates no signal.

Returns

BindProp[]

Inherited from

Viewer.bindProps

bindStep()

bindStep(name): BindSource | Signal<unknown> | null

Defined in: js-api/src/viewer.ts:233

One binding step (DD5): a meta-declared prop's same-named Signal member — a named node is a bind source, generated off componentMeta the way getProperties is — then, under propertyTier, a cached signal over the declared property. '' answers the default binding: the component's own value signal, where one exists.

Parameters

Parameter	Type
`name`	`string`

Returns

BindSource | Signal<unknown> | null

Inherited from

Viewer.bindStep

close()

close(): void

Returns

void

Inherited from

Viewer.detach

dispose()

dispose(): void

Defined in: js-api/src/u2core/component.ts:141

On a never-engaged wrapper the getter mints here and _scopeMinted wires the lifecycle (own(kill) + the platform cleanup for Dart-owned), so dispose still kills it; re-entry from the kill cleanup is a no-op via the scope's disposed flag.

Returns

void

Inherited from

Viewer.dispose

Defined in: js-api/src/u2core/component.ts:128

Parameters

getOptions()

getOptions(includeDefaults?): object

Defined in: js-api/src/viewer.ts:200

`id`	`string`	js-api/src/viewer.ts:200

link()

link(name, source, twoWay): void

Defined in: js-api/src/u2core/component.ts:246

Keeps this component's name step and source equal, echo-suppressed by value; the reverse direction only where twoWay. A component that took source as its own signal needs no link and gets none; a read-only step cannot follow anything and gets none either.

build()

static build(builder): Control

Defined in: js-api/src/u2core/component.ts:470

Builds a control out of plain elements: builder runs with the new control's scope ambient, so signal bindings and nested components inside it are owned by the result.

Control
