In this example, you can see how to bind array object as data source for heatmap and configure the Heatmap using the data adaptor support. You can directly bind the array object to the Heatmap data source with default property settings.

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