This sample illustrates an area series with empty points. Data points with null points are shown here.
In this example, you can see how to render an area series with empty points. Also, a legend is enabled in the shape of the series.

Chart component features are segregated into individual feature-wise modules. To use area series, we need to inject AreaSeries module into services.
More information on the area series can be found in this documentation section.
