有没有一种向热图添加序列函数的方法？

Question

我已经在网站上实现了热图代码，但是我需要能够对多年的数据进行排序。我使用了leaflet-heat.js插件。https://github.com/Leaflet/Leaflet.heat/tree/gh-pages/dist 我希望它从顺序栏中更改日期。 picture of current heatmap without sequence bar working

函数createHeatMap（花粉）{

var locations = pollen.features.map(function(row) {
  // the heatmap plugin wants an array of each location
  var location = row.geometry.coordinates.reverse();
  location.push(0.9);
  return location; // [50.5, 30.5, 0.2], [lat, lng, intensity]
});

  var heat = L.heatLayer(locations, { 
   minOpacity: 0.3,
   radius: 20,
    blur:10,
    maxZoom:5,
    max:50,
   gradient: {
       0.1: 'purple',
       0.2: 'cyan',
       0.3: '#2b83ba',
       0.4: 'green',
       0.6: 'yellow',
       0.8: 'orange',
       0.9: '#d7191c',
       1: 'red'
   } 

}）;

map.addLayer(heat);

};
