ScatterplotLayer

The Scatterplot Layer takes in paired latitude and longitude coordinated points and renders them as circles with a certain radius.

import DeckGL, {ScatterplotLayer} from 'deck.gl';

const App = ({data, viewport}) => {

  /**
   * Data format:
   * [
   *   {position: [-122.4, 37.7], radius: 5, color: [255, 0, 0]},
   *   ...
   * ]
   */
  const layer = new ScatterplotLayer({
    id: 'scatterplot-layer',
    data,
    radiusScale: 100,
    outline: false
  });

  return (<DeckGL {...viewport} layers={[layer]} />);
};

Properties

Inherits from all Base Layer properties.

Render Options

radiusScale (Number, optional)

• Default: 1

A global radius multiplier for all points.

outline (Boolean, optional)

• Default: false

Only draw outline of points.

strokeWidth (Number, optional)

• Default: 1

Width of the outline, in pixels. Requires outline to be true.

radiusMinPixels (Number, optional)

• Default: 0

The minimum radius in pixels.

radiusMaxPixels (Number, optional)

• Default: Number.MAX_SAFE_INTEGER

The maximum radius in pixels.

fp64 (Boolean, optional)

• Default: false

Whether the layer should be rendered in high-precision 64-bit mode.

Data Accessors

getPosition (Function, optional)

• Default: object => object.position

Method called to retrieve the position of each object.

getRadius (Function, optional)

• Default: object => object.radius

Method called to retrieve the radius of each object.

getColor (Function, optional)

• Default: object => object.color

Method called to retrieve the rgba color of each object.

• If the alpha parameter is not provided, it will be set to 255.
• If the method does not return a value for the given object, fallback to [0, 0, 0, 255].
