In this example, you can see how to bind JSON data and configure the Heatmap using the data adaptor support. You can bind the JSON data with information for each individual cell to the Heatmap using isJsonData and by defining the adaptorType properties. In cell JSON data, the value for each cell is mapped using the xDataMapping , yDataMapping and valueMapping properties.

Tooltip is enabled in this example, to see the tooltip in action, hover a point or tap on a point in touch enabled devices.


Injecting Module

Heatmap component features are segregated into individual feature-wise modules. To use data adaptor support, we need to inject Adaptor module using Heatmap.Inject(Adaptor) method, to use a tooltip, inject the Tooltip module using the Heatmap.Inject(Tooltip) method, and use a legend by injecting the Legend module using the Heatmap.Inject(Legend) method.
