Intensity doesn't affect gradient

[FrankieDuck]

Hello,

I have been working with this package and from my understanding the intensity doesn't affect the gradient? What does seem to affect the gradient is how close a point is to other points, that also changes depending on zoom level. So a cluster of points will have a higher intense gradient.

Is there anyway to directly use the intensity value to control the gradient that is passed to the heat layer? I want to represent points with higher values as a darker colour as opposed to lower values with a lighter gradient. With the current functionality a point with an intensity value of 0.77 would have the same colour as one with 0.22.

So, instead of a heatmap based on coordinates proximity to each other, I want it to be affected by the strength value of each coordinate.

thank you any help!

an example of my array would be like this:
[60300, 86220, 0.67],
[64122, 85670, 0.23]

~code below

const HeatmapComponent = ({ heatMapData }) => {
  const map = useMap()

  useEffect(() => {
    const points = heatMapData ?.map((data) => {
      const lat = data[0][0]
      const lng = data[0][1]
      const str = data[0][2]

      return [lat, lng, str]
    })

    const heatLayer = L.heatLayer(points, {
      minOpacity: 0.5,
      maxZoom: map.getMaxZoom(),
      max: 1.0,
      radius: 15,
      blur: 15,
    }).addTo(map)

    return () => {
      map.removeLayer(heatLayer)
    }
  }, [heatmapCords, map])

I have exact same problem. However I think it works based on intensity but it also groups those values together based on radius and when you zoom in/out it changes and usually looks really bad...

Not sure if this will work for you, but I modified the code slightly to fit my use case.

In the file dist/leaflet-heat.js, I updated the _redraw function to use intensity directly instead of calculating it based on the zoom level.

Specifically, I changed this code on line 11 (the entire function is on this line):

;r=x*f,

to:

;r=this._latlngs[t][2],
