The ChartBase class is the link between the Flex component architecture and the DualStyleObject architecture. It extends the Flex UIComponent base class, but contains DualStyleObject classes.

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.

Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

A flag that specifies whether dragged items can be dropped onto the chart.

If you set this property to true, the chart accepts all data formats, and assumes that the dragged data matches the format of the data in the data provider. To explicitly check the data format of the data being dragged, you must handle one or more of the drag events, such as dragOver, and call the preventDefault() method of the DragEvent to customize the way the list class accepts dropped data.

When dropEnabled is set to true, Flex automatically calls the showDropFeedback() and hideDropFeedback() methods to display the drop indicator.

The default value is false.
