ChartBase  - AS3 Flex

The set of all chart elements displayed in the chart. This set includes series, second series, background elements, and annotation elements.

Sets an array of ChartElement objects that appears on top of any data series rendered by the chart. Each item in the array must extend the mx.charts.DualStyleObject class and implement the IChartElement2 interface.

Sets an array of background ChartElement objects that appear below any data series rendered by the chart. Each item in the Array must extend the mx.charts.DualStyleObject class and implement the IChartElement2 interface.

The current transition state of the chart. Use this property to determine whether the chart is currently transitioning out its old data, transitioning in its new data, or has completed all transitions and is showing its current data set. See the mx.charts.chartClasses.ChartState enumeration for possible values.

Determines whether Flex clips the chart to the area bounded by the axes. Set to false to clip the chart. Set to true to avoid clipping when the data is rendered.

Specifies the data provider for the chart. Data series rendered by the chart are assigned this data provider. To render disparate data series in the same chart, use the dataProvider property on the individual series.

This property can accept an array or any other object that implements the IList or ICollectionView interface.

The area of the chart used to display data. This rectangle excludes the area used for gutters, axis lines and labels, and padding.

Specifies a callback method used to generate data tips from values. This method should use the following signature:

      function dataTipFunction(hitData:HitData):String
      

This method returns a string that is displayed for each data point. The text can include HTML formatting. The single parameter is a HitData object that describes the data point.

The index of the child that is responsible for rendering data tips. Derived classes that add visual elements to the chart should add them below this layer.

Specifies how Flex displays DataTip controls for the chart. DataTip controls are similar to ToolTip controls, except that they display an appropriate value that represents the nearest chart data point under the mouse pointer.

Possible values of dataTipMode are:

• "single" - Data tips are shown for the closest data point to the mouse cursor.
• "multiple" - Data tips are shown for any DataTip control within range of the mouse cursor. You can control the sensitivity with the mouseSensitivity property.

You can customize DataTip controls with the dataTipFunction property.

A short description of the data in the chart. When accessibility is enabled, screen readers use this property to describe the chart.

This string defaults to the empty string, and must be explicitly assigned by the developer to have meaning.

Specifies whether you can drag items out of this chart and drop them on other controls. If true, dragging is enabled for the chart. If the dropEnabled property is also true, you can drag items and drop them in the chart to reorder the items.

The default value is false.

Gets an instance of a class that displays the visuals during a drag-and-drop operation.

The default value is mx.controls.chartClasses.ChartItemDragProxy.

Indicates which display cursor to show as drag feedback. If true, and the dragEnabled property is true and the Control key is not held down, moveCursor is shown as feedback. If the Control key is held down, copyCursor is shown. If false and the dragEnabled property is true, then copyCursor is shown whether the Control key is held down or not.

The default value is false.

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.

The set of display objects that represent the labels for the chart elements. Some series, annotation, and background types include overlays such elements and callouts. Elements can pass a display object to the chart that contains the overlays to be placed on top of all other chart elememnts. Chart implementors can access these overlay objects in the labelElements array.

An array of Legend items.

This property can be used as the source for data binding. When this property is modified, it dispatches the legendDataChanged event.

A module factory is used as context for using embedded fonts and for finding the style manager that controls the styles for this component.

Specifies the distance, in pixels, that Flex considers a data point to be under the mouse pointer when the pointer moves around a chart. Flex considers any data point less than mouseSensitivity pixels away to be under the mouse pointer. This value is also used by the findDataPoints method.

The default value is 5.

Specifies the selected ChartItem in the chart. If multiple items are selected, this property specifies the most recently selected item.

Specifies an array of all the selected ChartItem objects in the chart.

Specifies whether or not ChartItem objects can be selected. Possible values are none, single, or multiple. Set to none to prevent chart items from being selected. Set to single to allow only one item to be selected at a time. Set to multiple to allow one or more chart items to be selected at a time.

The default value is none.

Related API Elements

An array of Series objects that define the chart data. Each chart defines the type of Series objects that you use to populate this array. For example, a ColumnChart control expects ColumnSeries objects as part of this array. Some charts accept any object of type IChartElement2 as part of the array, but in general each chart expects a specific type.

An array of filters that are applied to all series in the chart. Assign an array of bitmap filters to this property to apply them to all the series at once. Set the seriesFilter property to an empty array to clear the default filters on the chart's series. Assigning filters to the seriesFilters property, which applies to all series, is more efficient than assigning them to individual series.

Specifies whether Flex shows all DataTip controls for the chart. DataTip controls are similar to tool tips, except that they display an appropriate value representing the chart data point.

Different chart elements might show different styles of DataTip controls. For example, a stacked chart element might show both the values of the column and the percentage that it contributes to the whole.

You can customize DataTip controls with the dataTipFunction property.

Constructor.

Adds the selected items to the DragSource object as part of a drag and drop operation. You can override this method to add other data to the drag source.

Parameters

Preprocesses the series and transform for display. You typically do not call this method directly. Instead, this method is called automatically during the chart control's commitProperties() cycle when the series has been invalidated by a call to the invalidateSeries() method.

By default, this method calls the customizeSeries() method once for each series in the set. Chart subclasses can override this method to add customization logic that is global to the whole series set.
