Thanks, Rick for this useful summary of these features. Often, users will wonder why their plots do not display the marker symbols that they have defined in the STYLEATTRS statement. This is usually because the HTMLBlue style is in effect (ATTRPRIORITY=COLOR), which delays the use of the symbols. By default, HTMLBlue is one of the few styles that uses ATTRPRIORITY=COLOR. (Pearl and Sapphire are others.) Most SAS shipped styles have ATTRPRIORITY=none. This can be changed in the style itself, or on the ODS GRAPHICS statement or in BEGINGRAPH GTL statement.
