The ReactNYC component accepts the following props
Name | Type | Default | Req/Opt | Description
--- | --- | --- | --- | ---
mapboxAccessToken | string | | Required | Access Token from Mapbox
mapHeight | string | | Required | Height of the map
mapWidth | string | 100% | Optional | Width of the map. Default value is 100% of the containing element
className | string | | Optional | Class name to be applied to the map
mapboxType | string | streets | Optional | Mapbox provides many types of map themes. This component supports 5 such themes: light, dark, streets, outdoors, and satellite. Default value is streets
mapCenter | array | [40.7831, -73.9712] | Optional | Geographical coordinates (latitude and longitude) where the map should be centered. Default value is [40.7831, -73.9712]
mapZoom | integer | 12 | Optional | Initial zoom level for the map. Default value is 12
mapScrollZoom | boolean | false | Optional | Indicates whether the map can be zoomed by using the mouse wheel. Default value is false
neighborhoodOn | boolean | true | Optional | Indicates whether the neighborhood tiles should be displayed. Default value is true
tooltip | boolean | true | Optional | Indicates whether the tooltip should appear when hovering over a neighborhood tile. Default value is true
tooltipSticky | boolean | false | Optional | If true, the tooltip will follow the mouse instead of being fixed at the feature center. Default value is false
neighborhoodStyle | object | | Optional | Style of the neighborhood tile. This overrides the default style, which is { weight: 1, opacity: 1, color: '#666', dashArray: '3', fillOpacity: 0.7 }
neighborhoodHoverStyle | object | | Optional | Style of the neighborhood tile when hovered over. This overrides the default style, which is { weight: 5, color: '#FFF', dashArray: '1', fillOpacity: 0.7 }
excludeNeighborhoods | array | | Optional | To exclude any neighborhoods from the map, provide the neighborhood names in an array. Default will show all 38 neighborhoods
data | array | | Optional | See the Data section below for details
Note on hover styles: To ensure that the tile style behaves as expected when hovered over and away from the tile, please include matching CSS properties in both neighborhoodStyle and neighborhoodHoverStyle. For example, if the fillOpacity CSS property is defined in neighborhoodStyle, then please define fillOpacity in neighborhoodHoverStyle as well, and vice versa. Otherwise, some properties assigned during hover will remain even when hovered away and vice versa.
Data
The data prop is an array of objects. Each object is dedicated to a neighborhood and must have the following keys:
name: Name of the neighborhoodvalues: Array of objects with keyslabelandvalcolor: Color of the neighborhood tile. If color is unspecified, the default color for all tiles is#FFEDA0
For example, if you want to highlight the below neighborhoods with their data, then simply pass the below data array of objects.
const data = [
{
name: "Chelsea",
values: [{label: "Population", val: 20000}, {label: "Restaurants", val: "690"}],
color: "#E31A1C"
},
{
name: "Upper West Side",
values: [{label: "Population", val: "20,000"}],
color: "#666"
}
]ColorBrewer is a nice tool that helps you choose nice colors for neighborhood tiles
