How can I print a graph in landscape, rather than portrait, orientation?

With most programs, you set the page orientation in the printer setup dialog. Prism uses this setting only when printing results and data. You can tell Prism to use a different orientation for each graph and each layout. Don't use the printer setup dialog. Instead, from the graph or layout sheet, click "Change... Page Orientation..." (ver 3) or choose "Change... Graph Type..." and select the "Graph Type" tab (ver 4).
