A page by variable will split the report into pages by a variable, and label each page according the variable value. The page by can be assigned to the report, to a table, or to a plot. The page by label will appear between the titles and the content body. It can be aligned left, right, or center. The data should be sorted by the page by variable prior to reporting.
