SAS/QC Graphics


The following SAS/QC procedures produce graphical output:

  • ANOM








The ISHIKAWA procedure ( Chapter 8, The ISHIKAWA Procedure, ) provides an interactive environment for creating Ishikawa diagrams. This discussion applies to the other procedures, which generate charts and other graphical displays when you specify appropriate statements and options.

SAS/QC procedures can produce three types of graphical output:

  • traditional graphics output

  • ODS Statistical Graphics output

  • legacy line printer (character-based) displays

SAS/QC procedures produce traditional graphics by default. These graphs are saved in graphics catalogs with entry type GRSEG, and their appearance is controlled by global statements such as the GOPTIONS, AXIS, and SYMBOL statements, which are described in SAS/GRAPH: Reference. In addition, SAS/QC procedures provide numerous options for controlling the appearance of traditional graphics.

In SAS 9.2, as an alternative to traditional graphics, SAS/QC procedures can use ODS Statistical Graphics functionality to create graphs. ODS Statistical Graphics (or ODS Graphics for short) is an extension to the Output Delivery System (ODS) that is invoked when you provide the ODS GRAPHICS statement prior to your procedure statements. Graphs are produced in standard image file formats (such as PNG) instead of graphics catalogs, and the details of their appearance and layout are controlled by ODS styles and templates rather than global statements and procedure options. Graphical output produced by SAS/QC procedures using ODS Graphics is consistent in appearance with graphical output produced by statistical procedures using ODS Graphics.

SAS/QC procedures continue to support legacy line printer charts and plots, drawn with characters, which are produced in the SAS output listing. You must specify the LINEPRINTER option in the PROC statement to request these displays.
