The SeriesZoomInstance class implements the instance class for the SeriesZoom effect. Flex creates an instance of this class when it plays a SeriesZoom effect; you do not create one yourself.

Property Detail

horizontalFocus

property

public var horizontalFocus:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Defines the location of the focul point of the zoom.

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

The default value is "center".

You combine the horizontalFocus and verticalFocus properties to define where the data series zooms in and out from. For example, set horizontalFocus to "left" and verticalFocus 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 verticalFocus to "center" to zoom chart elements to and from a horizontal line along the middle of the chart's bounding box.

relativeTo

property

public var relativeTo:String = "series"

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

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

Valid values for relativeTo are "series" and "chart". The default value is "series".

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.

verticalFocus

property

public var verticalFocus:String

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Defines the location of the focul point of the zoom.

Valid values of verticalFocus are "top", "center", "bottom", and null. The default value is "center".

For more information, see the description of the horizontalFocus property.
