Events

Type	Phases	Description
org.apache.myfaces.trinidad.event.AttributeChangeEvent	Invoke Application, Apply Request Values	Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

Attributes

Name	Type	Supports EL?	Description
action	javax.el.MethodExpression	Yes	A reference to an action method sent by the component, or the static outcome of an action.
attributeChangeListener	javax.el.MethodExpression	Only EL	a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
binding	oracle.adf.view.faces.bi.component.chart.UIDataItem	Only EL	Specifies a binding reference to store a specific instance of UIDataItem from a backing bean. Set this attribute only to access code in a backing bean.
borderColor	String	Yes	Specifies the border color for the data item.
color	String	Yes	Specifies the color for the data item.
group	Object	Yes	Specifies the group category for the data item.
id	String	No	Specifies the identifier for the component
label	String	Yes	Specifies the data label of the data item.
labelPosition	String	Yes	Valid Values: auto, center, aboveMarker, belowMarker, beforeMarker, afterMarker, insideBarEdge, outsideBarEdge Default Value: auto Specifies the position of the data label. Valid values are: auto - (default) The data label is centered on stacked bars and bubble charts, insideBarEdge for non-stacked bars, and after the marker on line, area and scatter charts. center - Centered on the data point. aboveMarker - above the data marker on line, area, scatter and bubble charts. belowMarker - below the data marker on line, area, scatter and bubble charts. beforeMarker - before the data marker on line, area, scatter and bubble charts. (To the left in non-bidi, right in bidi locale) afterMarker - after the data marker on line, area, scatter and bubble charts. (To the right in non-bidi, left in bidi locale) insideBarEdge - at the edge of the bar, inside. outsideBarEdge - on top of bars with positive value, just below for bars with negative value. The 'aboveMarker', 'belowMarker', 'beforeMarker', and 'afterMarker' values are ignored for bars, and position will fall back to 'auto' if set to those values. Similarly, 'insideBarEdge' and 'outsideBarEdge' are ignored for non-bar graph types. Bubble graphs calculate the optimal text size for the centered data labels. If centered and the label is too long to fit on the data point, the label is automatically dropped for bar and truncated for bubble.
labelStyle	String	Yes	Specifies the font style for the labels. Accepts font-related CSS attributes like font-name, font-weight, font-size, color, etc.
markerDisplayed	boolean	Yes	Default Value: false Specifies whether the data item markers are displayed. Only applies to line or area series types.
markerShape	String	Yes	Valid Values: auto, square, circle, diamond, plus, triangleDown, triangleUp, human Default Value: auto Returns the shape of the data item marker. Default value is "auto".
markerSize	Number	Yes	Returns of size of the data item marker, if one is displayed. Does not apply to bars in a bar chart. In a bubble chart, the proportional size of data item's marker is determined by the z attribute value.
pattern	String	Yes	Valid Values: auto, smallChecker, smallCrosshatch, smallDiagonalLeft, smallDiagonalRight, smallDiamond, smallTriangle, largeChecker, largeCrosshatch, largeDiagonalLeft, largeDiagonalRight, largeDiamond, largeTriangle Default Value: auto Specifies the built-in pattern used to fill the node. Default value is "auto". The pattern is drawn with a white background, and the foreground color is taken from the color attribute.
rendered	boolean	Yes	Default Value: true Specifies whether the component is rendered. The default value is true.
series	Object	Yes	Specifies the series category for the data item.
shortDesc	String	Yes	Specifies the description for the data item. This is used for accessibility and also for customizing the tooltip text. If this value is not specified, the default tooltip text will be used for accessibility.
value	Number	Yes	Specifies the value of the data item.
x	Object	Yes	Specifies the x value of the data item.
y	Number	Yes	Specifies the y value of the data item.
z	Number	Yes	Specifies the z value of the data item. Only applies to bubble charts, where this value determines the proportional size of the data item.
