Overview of Generating Web Output with the Annotate Facility

You can use the Annotate facility to enhance your Web presentation, or you can generate an entire Web presentation using Annotate and the GANNO procedure. In either case you can use the Annotate facility to generate drill-down presentations with the GIF, JPEG, or PNG device driver.

Note that your graph may conceal your annotations unless your annotations are specified with the option WHEN=AFTER. Specifying this option causes the annotations to be displayed after the graph, so that they will not be occluded. This is particularly important for interactive presentations, where the back wall of the graph may be made visible by default.

Note also that annotations disappear when the Web user selects another graph type. The annotations reappear when the Web user selects the Refresh button in the Web browser.

To learn how to use Annotate data sets to generate drill-down Web presentations, see Generating Web Output with the Annotate Facility on page 499.

Reference information on generating and applying Annotate data sets is provided in Chapter 25, Annotate Dictionary, on page 613. Usage information is provided in Chapter 24, Using Annotate Data Sets, on page 587. For information on the GANNO procedure, see Chapter 26, The GANNO Procedure, on page 707.
