The SeriesZoom effect implodes and explodes chart data into and out of the focal point that you specify. As with the SeriesSlide effect, whether the effect is zooming to or from this point depends on whether it is assigned to the showDataEffect or hideDataEffect effect trigger.

The <mx:SeriesZoom> tag inherits all the properties of its parent classes, and adds the following properties:

  <mx:SeriesZoom
    Properties
    horizontalFocus="center|left|right|null"
    relativeTo="series|chart"
    verticalFocus="top|center|bottom|null"

Detalhes da propriedade

horizontalFocus

propriedade

public var horizontalFocus:String

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 3

Versões de runtime:

Flash Player 9, AIR 1.1

Defines the location of the focul point of the zoom.

Valid values of the horizontalFocus property are "left", "center", "right", and null.

You combine the horizontalFocus and verticalFocus properties to define where the data series zooms in and out from. For example, set the horizontalFocus property to "left" and the verticalFocus property to "top" to zoom the series data to and from the top left corner of either the element or the chart (depending on the setting of the relativeTo property).

If you specify only one of these two properties, then the focus is a horizontal or vertical line rather than a point. For example, when you set horizontalFocus to "left" but verticalFocus to null, the element zooms to and from a vertical line along the left edge of its bounding box. Set the verticalFocus property to "center" to zoom chart elements to and from a horizontal line along the middle of the chart's bounding box.

O valor padrão é "center".

relativeTo

propriedade

public var relativeTo:String = "series"

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 3

Versões de runtime:

Flash Player 9, AIR 1.1

Controls the bounding box that Flex uses to calculate the focal point of the zooms.

Valid values for the relativeTo property are "series" and "chart".

Set to "series" to zoom each element relative to itself. For example, each column of a ColumnChart zooms from the top left of the column, the center of the column, and so on.

Set to "chart" to zoom each element relative to the chart area. For example, each column zooms from the top left of the axes, the center of the axes, and so on.

O valor padrão é "series".

verticalFocus

propriedade

public var verticalFocus:String

Versão da linguagem:

ActionScript 3.0

Versão de produto:

Flex 3

Versões de runtime:

Flash Player 9, AIR 1.1

Defines the location of the focal point of the zoom. For more information, see the description of the horizontalFocus property.

Valid values of verticalFocus are "top", "center", "bottom", and null.

O valor padrão é "center".
