8 You can specify more than one PLOT statement to produce multiple box plots. You can use options in the PLOT statement to do the following: control the style of the box-and-whiskers plots specify one of several methods for calculating quantile statistics (percentiles) add block legends and symbol markers to reveal stratification in data display vertical and horizontal reference lines control axis values and labels overlay the box plot with plots of additional variables control the layout and appearance of the plotThe INSET and INSETGROUP statements produce boxes or tables (referred to asinsets) of summarystatistics or other data on a box plot.

9 An INSET statement produces an inset of statistics pertaining to theentire box plot. An INSETGROUP statement produces an inset containing statistics calculated separately foreach group. An INSET or INSETGROUP statement by itself does not produce a display; it must be usedwith a PLOT can use options in an INSET or INSETGROUP statement to control insets in these ways: specify the position of the inset specify a header for the inset specify graphical enhancements, such as background colors, text colors, text height, text font, and dropshadowsTraditional graphics and ODS GraphicsThe BOXPLOT Procedure can produce two kinds of graphical output: traditional graphics ODS Statistical graphics outputGetting Started.

10 BOXPLOT ProcedureF1077 Traditional graphics are saved in graphics catalogs with entry type GRSEG. Their appearance is controlled byglobal statements such as the GOPTIONS, AXIS, and SYMBOL statements (as described inSAS/GRAPH:Reference) and numerous specialized PLOT statement options. You must have a SAS/GRAPH license toproduce traditional Statistical graphics (or ODS graphics for short) is an extension to the Output Delivery System (ODS).Graphs are produced in standard image file formats (such as PNG) instead of graphics catalogs, and thedetails of their appearance and layout are controlled by ODS styles and templates.
