Leaflet-Solr-Heatmap

A Leaflet plugin that visualizes heatmap facets from Solr 5.x

Using with Leaflet

// Create a SolrHeatmap layer and add it to the map
var solr = L.solrHeatmap('http://127.0.0.1:8983/solr/gettingstarted', {
  // Solr field with geospatial data (should be type Spatial Recursive Prefix Tree)
  field: 'loc_srpt',

  // Set type of visualization. Allowed types: 'geojsonGrid', 'clusters'
  // Note: 'clusters' requires LeafletMarkerClusterer
  type: 'geojsonGrid'
}).addTo(map);

Option	Type	Default	Description
field	String	null	Required. Solr field with geospatial data (should be type Spatial Recursive Prefix Tree)
type	String	'geojsonGrid'	Type of visualization. Accepts geojsonGrid, clusters and heatmap
solrRequestHandler	String	'select'	Request handler for Solr
colors	Array	['#f1eef6', '#d7b5d8', '#df65b0', '#dd1c77', '#980043']	Colors for heatmap. Array can be of any length.
