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.

commitProperties | () | metodo |
override protected function commitProperties():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.

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.
Parametri
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 | () | metodo |
override public function dataToLocal(... dataValues):Point| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
... dataValues — The data values to convert to coordinates.
|
Point — Coordinates that are relative to the chart.

describeData | () | metodo |
override public function describeData(dimension:String, requiredFields:uint):Array| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
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.
|
Array — An Array containing the DataDescription instances that describe
the data that is displayed.

drawCircle | () | metodo |
public function drawCircle(x:*, y:*, radius:Number):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
x:* — The x location of the center of the circle (in pixels).
| |
y:* — The y location of the center of the circle (in pixels).
| |
radius:Number — The radius of the circle (in pixels).

| Versioni runtime: | 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.
Parametri

invalidateDisplayList | () | metodo |
override public function invalidateDisplayList():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
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| Versione linguaggio: | ActionScript 3.0 |

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.
Parametri
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) | |
alpha:Number (default = 1.0) | |
pixelHinting:Boolean (default = false)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")
| |
caps:String (default = null)CapsStyle.NONE, CapsStyle.ROUND,
and CapsStyle.SQUARE. If a value is not indicated, use round caps.
| |
joints:String (default = null)JointStyle.BEVEL, JointStyle.MITER, and JointStyle.ROUND.
If a value is not indicated, use round joints.
| |
miterLimit:Number (default = 3)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 | () | metodo |
public function lineTo(x:*, y:*):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
x:* — The x coordinate of the drawing position.
| |
y:* — The y coordinate of the drawing position.

updateDisplayList | () | metodo |
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Parametri
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 | () | metodo |
protected function updateFilter():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
protected function validateData():void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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 | () | metodo |
protected function validateTransform():Boolean| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 3 |
| Versioni runtime: | 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.
Boolean — Returns true if updateTransform() was called. Otherwise, false.
