Annotations. The annotations features allow you to make notes of trend or observations anywhere on the plot. The Annotation can be an explanatory image or text, anchored to a single point or a coordinate on a chart's surface. Available annotation types: band, line, balloon, layer, view and cross line.
Trackball. This feature allows for even greater precision when reading the chart data. It displays a small popup containing information about the point where the trackball line crosses the visualization of a series object.
