Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

This class lets you use add graphical elements such as lines, ellipses, and other shapes by using a graphics API. The values that you pass to the graphics API are in data coordinates rather than screen coordinates. You can also add any DisplaObject to the canvas, in the same way that you add children to containers.

The drawing region for the canvas is determined by the verticalAxis and horizontalAxis, if they are specified. Otherwise, the canvas uses the default axes of the chart to compute the drawing region.

The data coordinates passed as parameters to the drawing APIs can be actual values of the data coordinate or an object of type CartesianCanvasValue, which can hold a data coordinate value and an offset, in pixels.

()

method

override public function addChild(child:DisplayObject):DisplayObject

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Adds a child DisplayObject after the end of this child list.

Calling childList.addChild(child) is the same as calling childList.addChild(child, childList.numChildren) After it has been added, its index of the new child will be (child.numChildren - 1)

Parameters

child:DisplayObject — The DisplayObject to add as a child.

Returns

DisplayObject — The child that was added; this is the same as the argument passed in.

addChildAt

()

method

override public function addChildAt(child:DisplayObject, index:int):DisplayObject

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Adds a child DisplayObject instance to this DisplayObjectContainer instance. The child is added at the index position specified. An index of 0 represents the back (bottom) of the display list for this DisplayObjectContainer object.

If you add a child object that already has a different display object container as a parent, the object is removed from the child list of the other display object container.

Parameters

	`child:DisplayObject` — The DisplayObject instance to add as a child of this DisplayObjectContainer instance.

	`index:int` — The index position to which the child is added. If you specify a currently occupied index position, the child object that exists at that position and all higher positions are moved up one position in the child list.

Returns

DisplayObject — The DisplayObject instance that you pass in the child parameter.

addDataChild

()

method

public function addDataChild(child:DisplayObject, left:*, top:*, right:*, bottom:*, hCenter:*, vCenter:*):void

Language Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Adds the specified display object as a child to the current canvas.

Parameters

	`child:DisplayObject` — The display object that is to be added as a child to current canvas.

	`left:*` (default = `NaN`) — Left x-coordinate of the `child` in data coordinates.

	`top:*` (default = `NaN`) — Top y-coordinate of the `child` in data coordinates.

	`right:*` (default = `NaN`) — Right x-coordinate of the `child` in data coordinates.

	`bottom:*` (default = `NaN`) — Bottom y-coordinate of the `child` in data coordinates.

	`vCenter:*` (default = `NaN`) — Middle y-coordinate of the `child` in data coordinates.

beginBitmapFill

()

method

 public function beginBitmapFill(bitmap:BitmapData, x:*, y:*, matrix:Matrix = null, repeat:Boolean = true, smooth:Boolean = true):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Fills a drawing area with a bitmap image. The coordinates that you pass to this method are relative to the canvas's horizontal axis and vertical axis.

The usage and parameters of this method are identical to the beginBitmapFill() method of the flash.display.Graphics class.

Parameters

	`bitmap:BitmapData` — A transparent or opaque bitmap image that contains the bits to be displayed.

	`x:*` (default = `NaN`) — The x coordinate of the fill.

	`y:*` (default = `NaN`) — The y coordinate of the fill.

	`matrix:Matrix` (default = `null`) — A matrix object (of the flash.geom.Matrix class), which you can use to define transformations on the bitmap.

	`repeat:Boolean` (default = `true`) — If `true`, the bitmap image repeats in a tiled pattern. If `false`, the bitmap image does not repeat, and the edges of the bitmap are used for any fill area that extends beyond the bitmap.

	`smooth:Boolean` (default = `true`) — If `false`, upscaled bitmap images are rendered by using a nearest-neighbor algorithm and look pixelated. If `true`, upscaled bitmap images are rendered by using a bilinear algorithm. Rendering by using the nearest neighbor algorithm is faster.

flash.display.Graphics.beginBitmapFill()

beginFill

()

method

public function beginFill(color:uint, alpha:Number = 1):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Specifies a simple one-color fill that subsequent calls to other Graphics methods (such as lineTo() or drawCircle()) use when drawing. The fill remains in effect until you call the beginFill(), beginBitmapFill(), beginGradientFill(), or beginShaderFill() method. Calling the clear() method clears the fill.

The application renders the fill whenever three or more points are drawn, or when the endFill() method is called.

Note: With the exception of the beginGradientFill() and beginShaderFill() methods, the following information from the flash.display.Graphics class's beginFill() method applies to this method:

Parameters

	`color:uint` — The color of the fill (0xRRGGBB).

	`alpha:Number` (default = `1`) — The alpha value of the fill (0.0 to 1.0).

commitProperties

()

method

override protected function commitProperties():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Processes the properties set on the component. This is an advanced method that you might override when creating a subclass of UIComponent.

You do not call this method directly. Flex calls the commitProperties() method when you use the addChild() method to add a component to a container, or when you call the invalidateProperties() method of the component. Calls to the commitProperties() method occur before calls to the measure() method. This lets you set property values that might be used by the measure() method.

Some components have properties that affect the number or kinds of child objects that they need to create, or have properties that interact with each other, such as the horizontalScrollPolicy and horizontalScrollPosition properties. It is often best at startup time to process all of these properties at one time to avoid duplicating work.

curveTo

()

method

public function curveTo(controlX:*, controlY:*, anchorX:*, anchorY:*):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Draws a curve using the current line style from the current drawing position to (anchorX, anchorY) and using the control point that (controlX, controlY) specifies. The coordinates that you pass to this method are in terms of chart data rather than screen coordinates.

The usage and parameters of this method are identical to the curveTo() method of the flash.display.Graphics class.

Parameters

	`controlX:*` — The x coordinate of the control point.

	`controlY:*` — The y coordinate of the control point.

	`anchorX:*` — The x coordinate of the anchor point.

	`anchorY:*` — The y coordinate of the anchor point.

dataToLocal

()

method

override public function dataToLocal(... dataValues):Point

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Converts a tuple of data values to an x-y coordinate on screen. Call this function to transform data on to the screen using the same transform that the individual elements go through. For example, to create a custom highlight for a data region of a chart, you might use this function to determine the on-screen coordinates of the range of interest.

For Cartesian chartelements, you typically pass two values. The first value maps to the horizontal axis, and the second value maps to the vertical axis.

For polar charts, the first value maps to the angular axis, and the second maps to the radial axis.

Parameters

... dataValues — The data values to convert to coordinates.

Returns

Point — Coordinates that are relative to the chart.

describeData

()

method

override public function describeData(dimension:String, requiredFields:uint):Array

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Called by the governing DataTransform to obtain a description of the data represented by this IChartElement. Implementors fill out and return an Array of mx.charts.chartClasses.DataDescription objects to guarantee that their data is correctly accounted for by any axes that are autogenerating values from the displayed data (such as minimum, maximum, interval, and unitSize). Most element types return an Array containing a single DataDescription. Aggregate elements, such as BarSet and ColumnSet, might return multiple DataDescription instances that describe the data displayed by their subelements. When called, the implementor describes the data along the axis indicated by the dimension argument. This function might be called for each axis supported by the containing chart.

Parameters

	`dimension:String` — Determines the axis to get data descriptions of.

	`requiredFields:uint` — A bitfield that indicates which values of the DataDescription object the particular axis cares about. Implementors can optimize by only calculating the necessary fields.

Returns

Array — An Array containing the DataDescription instances that describe the data that is displayed.

drawCircle

()

method

public function drawCircle(x:*, y:*, radius:Number):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Draws a circle. Set the line style, fill, or both before you call the drawCircle() method, by calling the linestyle(), lineGradientStyle(), beginFill(), beginGradientFill(), or beginBitmapFill() method. The coordinates that you pass to this method are in terms of chart data rather than screen coordinates.

Parameters

	`x:*` — The x location of the center of the circle (in pixels).

	`y:*` — The y location of the center of the circle (in pixels).

Applies a fill to the lines and curves that were added since the last call to the beginFill(), beginGradientFill(), or beginBitmapFill() method. Flash uses the fill that was specified in the previous call to the beginFill(), beginGradientFill(), or beginBitmapFill() method. If the current drawing position does not equal the previous position specified in a moveTo() method and a fill is defined, the path is closed with a line and then filled.

invalidateData

()

method

protected function invalidateData(invalid:Boolean = true):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Informs the canvas that the underlying data in the data provider has changed. This method triggers calls to the updateMapping() and updateTransform() methods on the next call to the commitProperties() method.

Parameters

invalid:Boolean (default = true) — true if the data provider's data has changed.

invalidateDisplayList

()

method

override public function invalidateDisplayList():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Marks a component so that its updateDisplayList() method gets called during a later screen update.

Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the width and height, it would be wasteful to update the component immediately after you change the width and then update again with the new height. It is more efficient to change both properties and then render the component with its new size once.

Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.

lineStyle

()

method

 public function lineStyle(thickness:Number, color:uint = 0, alpha:Number = 1.0, pixelHinting:Boolean = false, scaleMode:String = "normal", caps:String = null, joints:String = null, miterLimit:Number = 3):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Specifies a line style that Flash uses for subsequent calls to other Graphics methods (such as lineTo() or drawCircle()) for the object.

The usage and parameters of this method are identical to the lineStyle() method of the flash.display.Graphics class.

Parameters

	`thickness:Number` — An integer that indicates the thickness of the line in points; valid values are 0-255. If a number is not specified, or if the parameter is undefined, a line is not drawn. If a value of less than 0 is passed, the default is 0. The value 0 indicates hairline thickness; the maximum thickness is 255. If a value greater than 255 is passed, the default is 255.

	`color:uint` (default = `0`) — A hexadecimal color value of the line; for example, red is 0xFF0000, blue is 0x0000FF, and so on. If a value is not indicated, the default is 0x000000 (black).

	`alpha:Number` (default = `1.0`) — A number that indicates the alpha value of the color of the line; valid values are 0 to 1. If a value is not indicated, the default is 1 (solid). If the value is less than 0, the default is 0. If the value is greater than 1, the default is 1.

	`pixelHinting:Boolean` (default = `false`) — A Boolean value that specifies whether to hint strokes to full pixels. This affects both the position of anchors of a curve and the line stroke size itself. With `pixelHinting` set to true, line widths are adjusted to full pixel widths. With `pixelHinting` set to false, disjoints can appear for curves and straight lines.

	`scaleMode:String` (default = "`normal`") — A value from the flash.display.LineScaleMode class that specifies which scale mode to use: `LineScaleMode.NORMAL`: Always scale the line thickness when the object is scaled (the default). `LineScaleMode.NONE`: Never scale the line thickness. `LineScaleMode.VERTICAL`: Do not scale the line thickness if the object is scaled vertically only. `LineScaleMode.HORIZONTAL`: Do not scale the line thickness if the object is scaled horizontally only.

	`caps:String` (default = `null`) — A value from the flash.display.CapsStyle class that specifies the type of caps at the end of lines. Valid values are: `CapsStyle.NONE`, `CapsStyle.ROUND`, and `CapsStyle.SQUARE`. If a value is not indicated, use round caps.

	`joints:String` (default = `null`) — A value from the flash.display.JointStyle class that specifies the type of joint appearance used at angles. Valid values are: `JointStyle.BEVEL`, `JointStyle.MITER`, and `JointStyle.ROUND`. If a value is not indicated, use round joints.

	`miterLimit:Number` (default = `3`) — A number that indicates the limit at which a miter is cut off. Valid values range from 1 to 255 (and values outside that range are rounded to 1 or 255). This value is only used if the jointStyle is set to "miter". The `miterLimit` value represents the length that a miter can extend beyond the point at which the lines meet to form a joint. The value expresses a factor of the line thickness. For example, with a `miterLimit` factor of 2.5 and a thickness of 10 pixels, the miter is cut off at 25 pixels.

lineTo

()

method

public function lineTo(x:*, y:*):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Draws a line using the current line style from the current drawing position to (x, y); the current drawing position is then set to (x, y). If the display object in which you are drawing contains content that was created with the Flash drawing tools, calls to the lineTo() method are drawn underneath the content. If you call lineTo() before any calls to the moveTo() method, the default position for the current drawing is (0, 0). If any of the parameters are missing, this method fails and the current drawing position is not changed. Coordinates are in terms of data rather than screen coordinates. The coordinates that you pass to this method are in terms of chart data rather than screen coordinates.

Parameters

	`x:*` — The x coordinate of the drawing position.

	`y:*` — The y coordinate of the drawing position.

updateDisplayList

()

method

override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Draws the object and/or sizes and positions its children. This is an advanced method that you might override when creating a subclass of UIComponent.

You do not call this method directly. Flex calls the updateDisplayList() method when the component is added to a container using the addChild() method, and when the component's invalidateDisplayList() method is called.

If the component has no children, this method is where you would do programmatic drawing using methods on the component's Graphics object such as graphics.drawRect().

If the component has children, this method is where you would call the move() and setActualSize() methods on its children.

Components can do programmatic drawing even if they have children. In doing either, use the component's unscaledWidth and unscaledHeight as its bounds.

It is important to use unscaledWidth and unscaledHeight instead of the width and height properties.

Parameters

	`unscaledWidth:Number` — Specifies the width of the component, in pixels, in the component's coordinates, regardless of the value of the `scaleX` property of the component.

	`unscaledHeight:Number` — Specifies the height of the component, in pixels, in the component's coordinates, regardless of the value of the `scaleY` property of the component.

updateFilter

()

method

protected function updateFilter():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Called when the underlying data the canvas represents needs to be filtered against the ranges represented by the axes of the associated data transform. This can happen either because the underlying data has changed or because the range of the associated axes has changed. If you implement a custom canvas type, you should override this method and filter out any outlying data using the filterCache() method of the axes managed by its associated data transform. The filterCache() method converts any values that are out of range to NaN. You must be sure to call the super.updateFilter() method in your subclass. You should not generally call this method directly. Instead, if you need to guarantee that your data has been filtered at a given point, call the validateTransform() method of the CartesianDataCanvas class. You can generally assume that your updateData() and updateMapping() methods have been called prior to this method, if necessary.

validateData

()

method

protected function validateData():void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Calls the updateMapping() and updateFilter() methods of the canvas, if necessary. This method is called automatically by the canvas from the commitProperties() method, as necessary, but a derived canvas might call it explicitly if the generated values are needed at an explicit time. Loading and mapping data against the axes is designed to be acceptable by the axes at any time. It is safe this method explicitly at any point.

validateTransform

()

method

protected function validateTransform():Boolean

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Calls the updateTransform() method of the canvas, if necessary. This method is called automatically by the canvas during the commitProperties() method, as necessary, but a derived canvas might call it explicitly if the generated values are needed at an explicit time. Filtering and transforming of data relies on specific values being calculated by the axes, which can in turn depend on the data that is displayed in the chart. Calling this function at the wrong time might result in extra work being done, if those values are updated.

Returns

Boolean — Returns true if updateTransform() was called. Otherwise, false.
