24-48 Web User Interface Developers Guide for Oracle Application Development Framework ■ horizontalAlignment - Specifies the horizontal positioning of the annotation. This setting only applies when the annotation position attribute is absolute or percentage. Valid values are LEFT default, CENTER, LEADING, or RIGHT. ■ verticalAlignment - Specifies the vertical positioning of the annotation. This setting only applies when the annotation position attribute is absolute or percentage. Valid values are CENTER default, TOP, or BOTTOM.

24.9 Animating Graphs

Graph components dvt:areaGraph, dvt:bubbleGraph, dvt:barGraph, dvt:lineGraph, dvt:comboGraph, dvt:pieGraph, and dvt:scatterGraph support animation effects such as slideshow transition for initial display of the graph component and for partial page refresh PPR events. Animation effects are specified in the graph’s animationOnDisplay and animationOnDataChange properties with these values: ■ alphaFade ■ conveyorFromLeft ■ conveyorFromRight ■ cubeToLeft ■ cubeToRight ■ flipLeft ■ flipRight ■ slideToLeft ■ slideToRight ■ transitionToLeft ■ transitionToRight ■ zoom Animation effects can also be performed using active data. The Active Data Service ADS allows you to bind ADF Faces components to an active data source using the ADF model layer. To allow this, you must configure the components and the bindings so that the components can display the data as it is updated in the source. Alternatively, you can configure the application to poll the data source for changes at prescribed intervals.

24.9.1 How to Configure Graph Components to Display Active Data

To use the Active Data Service, you must have a data source that publishes events when data is changed, and you must create business services that react to those events and the associated data controls to represent those services. For more information about ADS and configuring your application, see the Using the Active Data Service chapter in the Oracle Fusion Middleware Fusion Developers Guide for Oracle Application Development Framework. Configure databound graphs to display active data by setting a value on the binding element in the corresponding page definition file. To configure a graph to display active data: 1. In the Structure window, select the graph node.
