autumnplot-gl / Barbs

Class: Barbs<ArrayType, MapType>

A class representing a field of wind barbs. The barbs are automatically thinned based on the zoom level on the map; the user only has to provide a thinning factor at zoom level 1.

Example

// Create a barb field with black barbs and plotting every 16th wind barb in both i and j at zoom level 1
const vector_field = new RawVectorField(grid, u_data, v_data);
const barbs = new Barbs(vector_field, {color: '#000000', thin_fac: 16});
