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: You can also use the Annotate
facility to enhance output from the ACTXIMG driver, but the ACTXIMG
driver does not support the GANNO procedure.
Note that your graph
may conceal your annotations unless your annotations are specified
with the value WHEN=A. 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.
