Blazor Chart with Annotation Example.
This sample illustrates speed data for the Interlagos circuit. In area-based series, data points can be annotated using symbols.
In this example, you can see how to render and configure the annotation feature in charts. An annotation can hold any HTML element as its content. In this example, an area chart depicting speed data for the Interlagos circuit has the circuit session data as its annotation content.
Tooltip is enabled in this example. To see the tooltip in action, hover over a point or tap on a point in touch-enabled devices. More information about the annotations can be found in this documentation section.
