RenderData structures are used by chart elements to store all of the relevant values and data needed to fully render the chart. Storing these values in a separate structure lets chart elements decouple their rendering from their assigned properties and data as necessary. This ability is used by the chart effects: effects such as SeriesInterpolate substitute temporary values calculated from previous and future renderData structures. Effects such as SeriesSlide and SeriesZoom substitute temporary RenderData structures with values calculated to render the effect correctly.

Property Detail

### bounds

property

`public var bounds:Rectangle`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

The bounds of all of the items a series displays on screen, relative to the series's coordinate system. This value is used by the various effects during rendering. A series fills in this value when the effect calls the `getElementBounds()` method. A series does not need to fill in this field unless specifically requested.

### cache

property

`public var cache:Array`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

The list of ChartItems representing the items in the series's `dataProvider`.

### elementBounds

property

`public var elementBounds:Array`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

An Array of rectangles describing the bounds of the series's ChartItems, relative to the series's coordinate system. Effects use this Array to generate the effect rendering. An effect calls the `getElementBounds()` method, which causes the series to fill in this value. A series does not need to fill in this field unless specifically requested. Effects modify this Array to relect current positions of the items during the effect duration. If this value is filled in on the series's `renderData`, the series renders itself based on these rectangles rather than from the series's data.

### filteredCache

property

`public var filteredCache:Array`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

The list of ChartItems representing the items in the series's `dataProvider` that remain after filtering.

### length

property

`length:uint` [read-only]

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

The number of items represented in this render data.

Implementation
`public function get length():uint`

### visibleRegion

property

`public var visibleRegion:Rectangle`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

The rectangle describing the possible coordinate range that a series can display on screen. This value is used by the various effects during rendering. An effect calls the `getElementBounds()` method to fill in this value. A series does not need to fill in this field unless specifically requested. If left `null`, effects assume the visible region of an element is the bounding box of the element itself (0, 0, width, height), expressed relative to the element.

Constructor Detail

### RenderData

()
Constructor

`public function RenderData(cache:Array = null, filteredCache:Array = null)`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

Constructor.

Parameters

| `cache:Array` (default = `null`)`` — The list of ChartItems representing the items in the series's `dataProvider`.
| `filteredCache:Array` (default = `null`)`` — The list of ChartItems representing the items in the series's `dataProvider` that remain after filtering.

Method Detail

### clone

()
method

`public function clone():RenderData`

Language Version: | ActionScript 3.0

Product Version: | Flex 3

Runtime Versions: | Flash Player 9, AIR 1.1

Creates a copy of the render data. In the new copy, properties that point to other objects continue to point to the same objects as the original.

If you subclass this class, you must override this method.

Returns

| `RenderData` — The new copy of the RenderData object.
