The attribute map feature
enables you to control the visual attributes that are applied to specific
data values in your graphs. For example, if you create a graph that
plots items sold in different countries, you can specify the display
attributes for the sales data of each country by name.
Attribute maps apply
only to group data. Attribute maps enable you to ensure that particular
visual attributes are applied based on the value of the data instead
of the position of the data in the data set.
Two main steps are
required for attribute mapping:
-
Create an SG attribute
map data set, which associates data values with particular visual
attributes. Each observation defines the attributes for a group value.
-
Modify the procedure
and its plot statements to use the data in the SG attribute map. You
can use attribute maps in the SGPLOT, SGPANEL, and SGSCATTER procedures
(not all plot statements support attribute maps).
