Types of Web Presentations Available

If you want to deliver your presentation to more operating environments than just Windows, you can use one of the following Java applets:

Like the ActiveX control, the Graph, Map, Tile Chart, and Contour applets display the output of SAS/GRAPH procedures and enable extensive interactive features. The Graph, Map, Tile Chart, and Contour applets enable interactive features such as data tips and drill-down links, and they provide pop-up menus which enable the user to change properties such as the graph's colors, legends, and axes.

Sample Java Presentation shows PROC GCHART output displayed by the Java Graph applet showing data tips and drill-down capability.

These applets display the output of the following SAS/GRAPH procedures: To create a graph to be displayed by one of these applets, specify DEVICE=JAVA on your GOPTIONS statement. For more information, see Using ODS HTML with a SAS/GRAPH Procedure and Creating Interactive Output for Java.

This applet displays a treeview diagram that shows the parent-child relationships in a tree structure. In a treeview diagram, each child node has exactly one parent, and each parent node has zero or more children. In other words, the relationships in a treeview diagram are one-to-many. A treeview diagram is ideal for displaying such data as organizational charts or the hierarchical relationships of the pages of a Web site.

By default, the Treeview applet zooms in on the portion of the tree that is in the center of the display, as if you were looking through a fish-eye lens. Nodes in the center of the display are spread apart and shown with more detail, including node labels. Nodes near the periphery of the display are compressed and shown with less detail. Initially, the Treeview applet places the root node in the center of the display. You can click and drag the diagram to change the portion of the diagram that is in the center of the display.

The Treeview applet supports a pop-up menu that enables you to search for nodes, select or hide subtrees, and so on. You can add hotspots that link to Web pages when the user clicks on a node.

To generate a treeview diagram, use the DS2TREE macro. For more information, see Creating Interactive Treeview Diagrams.

The Constellation applet displays a general node-link diagram. Each node can be linked to one or more other nodes. Unlike the Treeview applet, the Constellation applet does not require a hierarchical relationship between the nodes. (Although it can be used to display hierarchical relationships, the Constellation applet does not automatically place the root node at the center of the display.)

The Constellation applet supports node and link properties that determine the color and size of the nodes and the color and thickness of the link joining the nodes. These properties indicate the relative strength of the relationship between the nodes.

Like the Treeview applet, by default, the Constellation applet zooms in on the portion of the diagram that is in the center of the display, as if you were looking through a fish-eye lens. Nodes in the center of the display are spread apart and shown with more detail, including node labels. Nodes near the periphery of the display are compressed and shown with less detail. You can click and drag the diagram to change the portion of the diagram that is in the center of the display.

The Constellation applet has a pop-up menu that supports several functions such as highlighting specific links and searching for specific nodes. You can add hotspots that link to Web pages when the user clicks on a node.

To generate the Constellation applet, use the DS2CONST macro. For more information, see Creating Interactive Constellation Diagrams.

The Metaview applet displays the output of SAS/GRAPH procedures and enables interactive features that are not available with static images such as GIFs or JPEGs. It enables zooming and scrolling and supports pop-up menus with customized user-selectable links. When you generate a graph with the Metaview applet, you can specify background colors and text fonts, and enable drill-down links to HTML files, metagraphics files, and sets of metacodes.

The Metaview applet displays output from the G3D, GANNO, GBARLINE, GCHART, GCONTOUR, GPLOT, GMAP, GRADAR, GREPLAY, and GSLIDE procedures. To create a graph to be displayed by the Metaview applet, specify DEVICE=JAVAMETA on your GOPTIONS statement.

If you do not need any interactive features in your presentations, then you can specify one of the following device drivers to generate a presentation that uses a GIF, JPEG, or PNG file. To generate a Web presentation that uses one of these drivers, specify the driver name with the DEVICE= option in your GOPTIONS statement. All of these device drivers generate output from SAS/GRAPH procedures.

For more information, refer to the following topics:

You can use the ACTXIMG device driver to create a presentation that uses a PNG file that is identical in appearance to the image produced with the ACTIVEX device driver.

A presentation generated with the ACTXIMG driver supports data tips and drill-down links for GCHART, GBARLINE, and GPLOT (except for high-low plots) output.

To render your output (create the PNG file), the ActiveX control must be installed on the PC where your SAS session is running. Because of this requirement, ACTXIMG presentations can be generated only on PCs. When you specify the ACTXIMG device driver, the output is rendered when your Web presentation is generated, and the user does not need to have the ActiveX control installed to view it.

You can use the ACTXIMG device driver to generate presentations with the same procedures that are supported by the ACTIVEX driver: G3D, GAREABAR, GBARLINE, GCHART, GCONTOUR, GPLOT, GMAP, GRADAR, and GTILE.

You can use the JAVAIMG device driver to create a presentation that uses a PNG file that is identical in appearance to the image produced with the JAVA device driver.

The appropriate Java applet (Graph, Map, Tile Chart, or Contour applet) is required to render your output (create the PNG file). The appropriate Java applet must be installed on the machine where your SAS session is running. When you specify the JAVAIMG device driver, the output is rendered when your Web presentation is generated, and the user does not need to have any Java applet files installed to view it.

You can use the JAVAIMG device driver to generate presentations with these procedures: G3D, GCHART, GCONTOUR, GPLOT, GKPI, and GTILE.

For Web presentations generated with the GIF, JPEG, or PNG device drivers, you can add pop-up data tips that are displayed when the cursor is over a portion of the image and links to other Web pages.

You can use the GIF, JPEG, or PNG device drivers to generate presentations to display output from the G3D, GANNO, GBARLINE, GCHART, GCONTOUR, GPLOT, GMAP, GRADAR, GREPLAY, and GSLIDE procedures.

To create a Web presentation with one of these devices, specify DEVICE=GIF, JPEG, or PNG in your GOPTIONS statement.

An animated presentation is a series of static images that are displayed automatically one after the other. Specify DEVICE=GIFANIM in your GOPTIONS statement to generate a Web presentation that displays a series of images from a single GIF file. You can control the rate at which the successive images are presented.

You can generate animated GIF presentations from the G3D, GANNO, GBARLINE, GCHART, GCONTOUR, GPLOT, GMAP, GRADAR, GREPLAY, and GSLIDE procedures.
