Installation

To install the dependencies from NPM:

npm install deck.gl
# or
npm install @deck.gl/core @deck.gl/layers

import {ScatterplotLayer} from '@deck.gl/layers';
import type {ScatterplotLayerProps} from '@deck.gl/layers';

new ScatterplotLayer<DataT>(...props: ScatterplotLayerProps<DataT>[]);

To use pre-bundled scripts:

<script src="https://unpkg.com/deck.gl@^9.0.0/dist.min.js"></script>

<script src="https://unpkg.com/@deck.gl/core@^9.0.0/dist.min.js"></script>
<script src="https://unpkg.com/@deck.gl/layers@^9.0.0/dist.min.js"></script>

new deck.ScatterplotLayer({});

Properties

Inherits from all Base Layer properties.

Render Options radiusUnits (string, optional)

Default: 'meters'

The units of the radius, one of 'meters', 'common', and 'pixels'. See unit system.

radiusScale (number, optional)

Default: 1

A global radius multiplier for all points.

lineWidthUnits (string, optional)

Default: 'meters'

The units of the line width, one of 'meters', 'common', and 'pixels'. See unit system.

lineWidthScale (number, optional)

Default: 1

A global line width multiplier for all points.

stroked (boolean, optional)

Default: false

Draw the outline of points.

filled (boolean, optional)

Default: true

Draw the filled area of points.

radiusMinPixels (number, optional)

Default: 0

The minimum radius in pixels. This prop can be used to prevent the circle from getting too small when zoomed out.

radiusMaxPixels (number, optional)

Default: Number.MAX_SAFE_INTEGER

The maximum radius in pixels. This prop can be used to prevent the circle from getting too big when zoomed in.

lineWidthMinPixels (number, optional)

Default: 0

The minimum line width in pixels. This prop can be used to prevent the stroke from getting too thin when zoomed out.

lineWidthMaxPixels (number, optional)

Default: Number.MAX_SAFE_INTEGER

The maximum line width in pixels. This prop can be used to prevent the path from getting too thick when zoomed in.

billboard (boolean, optional)

Default: false

If true, rendered circles always face the camera. If false circles face up (i.e. are parallel with the ground plane).

antialiasing (boolean, optional)

Default: true

If true, circles are rendered with smoothed edges. If false, circles are rendered with rough edges. Antialiasing can cause artifacts on edges of overlapping circles. Also, antialiasing isn't supported in FirstPersonView.

Data Accessors getPosition (Accessor<Position>, optional)

Default: object => object.position

Method called to retrieve the position of each object.

getRadius (Accessor<number>, optional)

Default: 1

The radius of each object, in units specified by radiusUnits (default meters).

If a number is provided, it is used as the radius for all objects.
If a function is provided, it is called on each object to retrieve its radius.

getColor (Accessor<Color>, optional)

Default: [0, 0, 0, 255]

The rgba color is in the format of [r, g, b, [a]]. Each channel is a number between 0-255 and a is 255 if not supplied.

If an array is provided, it is used as the color for all objects.
If a function is provided, it is called on each object to retrieve its color.

It will be overridden by getLineColor and getFillColor if these new accessors are specified.

getFillColor (Accessor<Color>, optional)

Default: [0, 0, 0, 255]

The rgba color is in the format of [r, g, b, [a]]. Each channel is a number between 0-255 and a is 255 if not supplied.

If an array is provided, it is used as the filled color for all objects.
If a function is provided, it is called on each object to retrieve its color.
If not provided, it falls back to getColor.

getLineColor (Accessor<Color>, optional)

Default: [0, 0, 0, 255]

The rgba color is in the format of [r, g, b, [a]]. Each channel is a number between 0-255 and a is 255 if not supplied.

If an array is provided, it is used as the outline color for all objects.
If a function is provided, it is called on each object to retrieve its color.
If not provided, it falls back to getColor.

getLineWidth (Accessor<number>, optional)

Default: 1

The width of the outline of each object, in units specified by lineWidthUnits (default meters).

If a number is provided, it is used as the outline width for all objects.
If a function is provided, it is called on each object to retrieve its outline width.
If not provided, it falls back to strokeWidth.
