%MAPLABEL Macro
Creates an output data set that can be used with
the ANNO= option for PROC GMAP.
| Variables written out: |
FUNCTION, STYLE, COLOR, SIZE, HSYS |
| Requirement: |
You must run the %ANNOMAC macro before using
any other annotate macros. For more information, see Making the Macros Available. |
Syntax
%MAPLABEL (map-dataset, attr-dataset,output-dataset,label-var,id-list,font=font_name,color=n,
size=n,hsys=n);
Parameters
- map-dataset
-
the name of the map
to be annotated.
- attr-dataset
-
the name of the data
set containing the text to be shown on each ID value.
- output-dataset
-
the name of the annotate
data set created by the macro.
- label-var
-
the name of the label
variable to place on the map (the text for annotate).
- id-list
-
the list of ID variables
that you would issue in PROC GMAP to create the map. These values
need to be on both the map and the attribute data sets. If you also
supply the SEGMENT variable, then every polygon will get a value.
Without the SEGMENT variable, only one label per ID set will be shown
over the collection of polygons. For example, Hawaii with SEGMENT
gets a label on each island, whereas without SEGMENT, there is only
one label centered on the entire set of islands.
- font
-
specifies a font name
for the STYLE variable.
- color
-
specifies a value for
the COLOR variable.
- size
-
specifies a value for
the SIZE variable. Defaults to 2.
- hsys
-
specifies a value for
the HSYS variable. Defaults to 3.
