Leaflet heatmap makes some weird shapes

[Amit]

hey,

I have started using leaflet.heatmap lately and I'm getting this result (attached file) for 20%~ of the heatmap instances.

 I've tried changing the radius and the blur, and even tho it does fix the problem for the very instance, it occurred on any around 20% of the following instances.

Thank you.

The image looks like a plausible heatmap. What is the problem with it? Can you give some more details? Can you make a fiddle or plunker that demonstrates the issue?

Thank you very much for answering.

The problem is with the unwanted ellipse shapes, I've made it more clear with the new image (attached).

Thank you.

The more detail you can provide, the more likely we can help :)

Some live representation of your issue would be ideal, but the following might help us to understand the problem a little more:

- There are a few heatmap plugins, but I was unable to find any strictly called "leaflet.heatmap". Which one are you using, it is on this list? - https://leafletjs.com/plugins.html#heatmaps

- What parameters did you use to produce the heatmap? 

- You mentioned you tried adjusting radius, what happens when you set it to a very, very, low number?

- Are there any open issues on the plugin's github repository that may be similar to what you are experiencing (this has helped me in the past)?

Thank you too for taking the time to help me.

-I'm using leaflet.heat.

-I'm using a vary of parameters and in all of the cases where I used slightly high radius parameter I got this result.

The parameters I'm using in the attached image are: radius 15.6, blur 21.6.

-When setting the radius to low, I don't get this problem.

-I couldn't find any similar issue in the internet.

In addition, the way I distribute my grid of points is symmetrical grid above a city, where all the points are within an equal distance from each other.

I haven't seen others use heat map this way, which may indicate the reason I'm having this issue.

Thanks again.
