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.
Official site for heatmap.js
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 beacons.
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.
Returns a heatmapInstance.
Use h337.create to create heatmap instances. A Heatmap can be customized with the configObject.
The configObject parameter is required.
Possible configuration properties:
Simple configuration with standard gradient
2 ) heatmapInstance
It return by h337.create
We have to add our data and all other customization in this.
It add data points to heatmap instance. It may be object or array.
Initializes a heatmap instance with a dataset. “min”, “max”, and “data” properties are required.
setData removes all previously existing points from the heatmap instance and re-initializes the datastore.
