Some data points were not marked with any values which indicates there are no deffective products and these data points are termed as empty points.
In this example, you can see how to render empty points in the Heatmap. The empty points or the points with no data can be marked using null in the data source. You can also customize the background color of the empty points by using the emptyPointColor property in paletteSettings 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.
