You typically do not use the ChartBase class directly. Instead you use one of its subclasses, such as PlotChart or BubbleChart. It acts as the base class for the common chart types provided in the mx.charts package.
This class defines a number of CSS styles and properties that provide easy access to the more common features of the framework.
A chart's minimum size is 20 x 20 pixels. A chart's maximum size is unbounded. A chart's preferred size is 400 x 400 pixels.
ChartBase objects, and its subclasses, augment the normal
mouse event objects with additional data that describes
the nearest chart data point under the mouse.
The event object for mouse events contains an additional property,
hitData, which contains a HitData object
that describes the nearest data point.
See mx.charts.HitData for more information on the contents
of the HitData object.
ChartBase objects consider data points only within a certain radius
of the mouse pointer.
You can set this radius using the mouseSensitivity
property.
If there is no data point within the mouseSensitivity
radius, event.hitData is null.
