地图SDK支持动态热力图功能，支持以3D的形式表示数据的密度和分布情况，示例图如下：

1.准备经纬度分布数据集,如

const data :Record<string, number>[] = [
    {"lng": 116.895579, "lat": 24.306521},
    {"lng": 113.951068, "lat": 22.772504},
    {"lng": 110.00006,  "lat": 40.603564},
    {"lng": 111.846788, "lat": 21.897821},
    {"lng": 120.607979, "lat": 28.022674},
    {"lng": 120.244238, "lat": 27.642108},
    {"lng": 113.304118, "lat": 23.154842},
    {"lng": 113.924164, "lat": 23.219795},
    {"lng": 101.692567, "lat": 36.945368}, 
    {"lng": 121.595172, "lat": 38.977931},
    {"lng": 117.215115, "lat": 39.211625},
    {"lng": 117.29184,  "lat": 34.208296},
]

2.设置热力图属性

// 获取热力图数据集
 const heatMapDatas = data.map(item=>{
    return new WeightedLatLng(new LatLng(item.lat,item.lng), 1)
})
//设置渐变色
const gradinet = new Gradient([
    'rgba(0,0,200,1)', 'rgba(0,225,0,1)', 'rgba(255,0,0,1)'
  ], [0.3, 0.7, 1.0]);

this.heatMap = new HeatMapBuilder().setDatas(heatMapDatas).gradientValue(gradinet).isRadiusMeterValue(true).radiusMeterValue(100).opacityValue(1.0).maxIntensityValue(1).frameAnimationValue(new HeatMapAnimation(true, 2000,AnimationType.OutQuad))
              .build();

3.添加热力图

this.mapController.addHeatMap(this.heatMap);

4.开启热力图帧动画

this.mapController.startHeatMapFrameAnimation();

5.停止热力图帧动画

this.mapController.stopHeatMapFrameAnimation();

6.调整热力图帧数

// 设置热力图为第2帧
this.mapController?.setHeatMapFrameAnimationIndex(1);
