Use the ViewType JSP tag to define a View Type tool to display apart from the View Toolbar. The View Type tool allows users change the type of a presentation between a thin crosstab and a thin graph.
If you use the Toolbar tag, then you do not need to define a View Type tool.
id -- (Required) A unique identifier for this tag.
scope -- Determines the accessibility and lifetime of the object; select one of the following values: Page, Request, Session, or Application. Typically, use Session, which is the default value.
presentationId -- (Required) Specifies the identifier of the Presentation tag with which the tool is associated. This presentation contains the query that will be displayed in the new view. The Presentation tag must be contained in the same page as the ViewType tag.
