/GVAR = VAR(country)
/GSET = ’World Countries’ LAYER=’World’
/TITLE = ’World Literacy Rates’
/BARMAP= VAR(lit_fema) VAR(lit_male)
SUM=(MEAN) INDSCALE=NO.
• This command creates a world map and places a bar chart on each country showing the
female and male literacy rates.
• Because the data contain only one record per country, the MEAN summary function yields
that value for each country.
• INDSCALE=NO is the default, included here for illustration. Because the same scale is used
for both variables, the bar heights allow you to compare relative female and male literacy
rates within each country. If it were YES, then both female and male literacy rates would
be relative to that in other countries but independent of each other.
PIEMAP Subcommand
VAR(v1) BY VAR(v2) V1 is the variable to be summarized within each pie; you can use
$COUNT instead of VAR(v1). V1 must be numeric. The values of v2
divide the pie into slices. V2 can be numeric or string and should have
no more than 10 distinct values. Both variables are required.
(SUM=function) The aggregation to be performed on V1 to produce the values represented
by the slices in each pie. Not required if the variable is
$COUNT.
DIAMETER The diameter of each pie. If GRADUATED=ON, this is the diameter of
the largest pie. The default is 0.25 inches (0.64 cm.).
GRADUATED When GRADUATED=YES, the diameters of pies within the map are
scaled according to the total value represented by the whole pie, enabling
comparisons between regions. The default is YES.
LEGENDTITLE The title for the legend. (DEFAULT) explicitly requests the default,
which is the label of the variable that determines the size of the slices
(V1 in the description), or blank if counts are shown.
VISIBLE Determines whether the theme is visible when the map is initially
drawn. The default is YES. The alternative, NO, is useful on multipletheme
maps where you intend to experiment with which themes to
show.
