Oracle Fusion Middleware Data Visualization Tools Tag Reference for Oracle ADF Faces 11g Release 1 (11.1.1.7.2) E12418-11 |
Use the alert tag for a graph to define an additional data point that needs to be highlighted with a separate symbol, such as an error or warning). An icon marks the location of the alert. When the mouse hovers over the alert icon, the text of that alert is displayed. In the case of a continuous time access graph, the alert does not have to reference an existing data point.
The alert tag is a child of the alertSet tag.
The following example shows the XML for two alert tags that are wrapped in an alertSet tag.
<dvt:graph> <dvt:alertSet> <dvt:alert xValue="Boston" yValue="3.50" yValueAssignment="Y1AXIS" imageSource="myWarning.gif"/> <dvt:alert xValue="Boston" yValue="5.50" yValueAssignment="Y1AXIS" imageSource="myError.gif"/> </dvt:alertSet> </dvt:graph>

xValue | java.lang.String | no | Indicates the x-axis or ordinal axis value for the alert.

yValue | double | no | Indicates the y-axis value for the alert. The value must be a Double. |
yValueAssignment | java.lang.String | no | Identifies which axis the yValue attribute is associated with. Valid values are:
