Method Detail
addChild()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.

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

Fills a drawing area with a bitmap image. Coordinate are in terms of the angularAxis or radialAxis properties of the canvas.

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) — Angle specifying the location of the fill.
 
y:* (default = NaN) — The distance, in pixels, from the center of the chart to 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.

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

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 dataProvider has changed. This function 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 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

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(angle:*, radial:*):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 (angle, radial); the current drawing position is then set to (angle, radial). 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.

Parameters

angle:* — The angle of the drawing position.
 
radial:* — The distance, in pixels, from the center of the chart to the drawing position.

mappingChanged()method 
override public function mappingChanged():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Called when the mapping of one or more associated axes changes. The DataTransform assigned to this ChartElement will call this method when any of the axes it represents is modified in some way.

moveTo()method 
public function moveTo(angle:*, radial:*):void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Moves the current drawing position to (angle, radial). 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.

Parameters

angle:* — The angle of the drawing position.
 
radial:* — The distance, in pixels, from the center of the chart to the drawing position.

removeAllChildren()method 
public function removeAllChildren():void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes all data children (DisplayObject instances) of the canvas.

removeChild()method 
override public function removeChild(child:DisplayObject):DisplayObject

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes the specified child DisplayObject from this child list.

Removing a child anywhere except from the end of a child list will decrement the indexes of children that were at higher indices.

The removed child will have its parent set to null and will be garbage collected if no other references to it exist.

Parameters

child:DisplayObject — The DisplayObject to remove.

Returns
DisplayObject — The child that was removed; this is the same as the argument passed in.
removeChildAt()method 
override public function removeChildAt(index:int):DisplayObject

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes the child DisplayObject at the specified index from this child list.

Removing a child anywhere except from the end of a child list will decrement the indexes of children that were at higher indices.

The removed child will have its parent set to null and will be garbage collected if no other references to it exist.

Parameters

index:int — The child index of the DisplayObject to remove.

Returns
DisplayObject — The child that was removed.
stripNaNs()method 
protected function stripNaNs(cache:Array, field:String):void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Removes any item from the provided cache whose field property is NaN. Derived classes can call this method from their updateFilter() implementation to remove any ChartItem objects that were filtered out by the axes.

Parameters

cache:Array — The data cache for the PolarDataCanvas object.
 
field:String — The value of the item's field property.

updateDataChild()method 
public function updateDataChild(child:DisplayObject, angleLeft:*, radialTop:*, angleRight:*, radialBottom:*, angleCenter:*, radialCenter:*):void

Language Version : ActionScript 3.0
Product Version : Flex 3
Runtime Versions : Flash Player 9, AIR 1.1

Updates the position of any child to the current canvas.

Parameters

child:DisplayObject — A DisplayObject instance that is to be added as a child of the current canvas.
 
angleLeft:* (default = NaN) — Left angular coordinate of the child, in data coordinates.
 
radialTop:* (default = NaN) — Top radial coordinate of the child, in data coordinates.
 
angleRight:* (default = NaN) — Right angular coordinate of the child, in data coordinates.
 
radialBottom:* (default = NaN) — Bottom radial coordinate of the child, in data coordinates.
 
angleCenter:* (default = NaN) — Middle angular coordinate of the child, in data coordinates.
 
radialCenter:* (default = NaN) — Middle radial coordinate of the child, in data coordinates.

For example:

          var lbl:Label = new Label();
          lbl.text = "Last Month";
          canvas.addChild(lbl);
          canvas.updateDataChild(lbl,200,20);
     

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 PolarDataCanvas 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 to call 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
Booleantrue if the underlying data of the data provider has changed; otherwise, false.
