How to implement heatmap.js with PHP?
A heat map is nothing but a representation of data in the two-dimensional form
which represents values by colors. A heat map can offer an appropriate and quick
visual summary of the information to the viewer. The detailed heat maps lets the
viewer understand the complex data sets.
Various things are available to show the heatmaps. Here in this article, we would
discuss about heatmap.js and ways to implement it with the help of PHP.

For live Example:
In this example we can show earthquake impact on different areas using color and
it can be easily understood by laymen.
We have to implement it on hall map to show beacon impact on users, .i.e. how
many users get notified by beacon.
We have added dynamic data to heatmap to show how many users pass from
It simply creates dynamic heatmaps based on the data you feed into it.
By looking at the above picture we easily understand where users visit most.
Firstly, we have to include heatmap.js
It has very simple configuration.
1 ) h337.create(configObject)
Use h337.create to create heatmap instances. A Heatmap can be customized with
The configObject parameter is required.
Possible configuration properties:
A DOM node where the heatmap canvas should be appended (heatmap will
adapt to the node's size)
A background color string in form of hexcode, color name, or rgb(a)
An object that represents the gradient (syntax: number string [0,1] : color
string), check out the example
The radius each datapoint will have (if not specified on the datapoint itself)
(number) [0,1] *optional* default = .6
A global opacity for the whole heatmap. This overrides maxOpacity and
minOpacity if set!
(number) [0,1] *optional*
