If you want to update radius with zoom level, you need to edit a couple methods. I actually experiment this idea a little bit and got some promising results.
First, I changed radius
function's signature and replaced r
with zoom
parameter.
radius: function (zoom, blur) {
blur = blur === undefined ? 15 : blur;
// recalculate radius based on zoom level
var r = this.defaultRadius * Math.pow(2, zoom - 15);
And updated draw method to accept current zoom level. I also made sure draw
method calls radius
method every time zoom
level is changed. Otherwise, radius
is called only once.
Here is a link to an example. It displays rectangles, not circles. You should be able to change it easily.

@zhuyinjing Sorry I don't remember which version was that, but you can just copy leaflet.heat code from https://jsfiddle.net/mertk/zawj9uwm/15/ and play with it.

Thanks @mertemin for the reply. Though I don't see the expected results but the radius does get recalculated on trying your logic. The intensities getting added up on zoom out is still blocking my expected result.

@mertemin hi,which version of leaflet.heat?3
And if i want to modify radius with different zoom level,can i use your code?
radius: function (zoom, blur) { blur = blur === undefined ? 15 : blur; // recalculate radius based on zoom level var r = this.defaultRadius * Math.pow(2, zoom - 15);
Is it need to modify the source code???
thanks you a lot!
