Baidu map heat map PHP class library

(function(w){
    // the heatmapFactory creates heatmap instances
    var heatmapFactory = (function(){
    // store object constructor
    // a heatmap contains a store
    // the store has to know about the heatmap in order to trigger heatmap updates when datapoints get added
    var store = function store(hmap){
        var _ = {
            // data is a two dimensional array
            // a datapoint gets saved as data[point-x-value][point-y-value]
            // the value at [point-x-value][point-y-value] is the occurrence of the datapoint
            data: [],
            // tight coupling of the heatmap object
            heatmap: hmap
        };
        // the max occurrence - the heatmaps radial gradient alpha transition is based on it
        this.max = 1;
        this.get = function(key){
            return _[key];
        };
        this.set = function(key, value){
            _[key] = value;
        };
    }

Set the detailed data displayed by the heat map. After implementation, it can be displayed immediately

@param {Json Object} data

{"max" : {Number} Maximum value of weight,

"data" : {Array} Coordinate detailed data, the format is as follows

{"lng":116.421969,"lat":39.913527,"count":3}, where

lng lat is the longitude and latitude respectively, count weight value

Add detailed coordinate points of the power map

@param {Number} lng longitude coordinate

@param {Number} lat longitude coordinate

@param {Number} count longitude coordinate
