Event Band Chart

A type of layout that displays a vertical band that represents time intervals for each row returned by a query. The x-axis represents time, and the y-axis represents a numeric variable that can be specified by creating an additional data layer. The event band chart is typically used in conjunction with other data layers to show correlations between temporal events and changes in other data.

Valid properties for Event Band Chart objects are described in the following table.

Property Data Type Description

When you set properties for Event Band Chart objects, you must also specify properties for Frame, Date Axis, Y Axis, Data Element, and Event Band objects. The association between an Event Band Chart object and supporting objects is represented in Figure A-4.
