Could we know that what kind of heatmap do you want:
The heatmap is on coordinateSystem: 'cartesian2d' or 'geo'?

我用的是 series: [{
name: 'Gaussian',
type: 'heatmap',
data: data,
//progressiveThreshold:3000,
//emphasis: {
// itemStyle: {
// borderColor: '#333',
// borderWidth: 100
// }
//},
progressive: 500000,

在数据达到200万左右页面就卡死，能提供一个分片加载的方法吗 就好像 散点图的appendData方法

希望官方抓紧支持，热力图百万以上的数据直接卡死
