Response variables can be specified for either the bar
chart or any line plot with the SUMVAR= option.
For example:
BAR age / DISCRETE SUMVAR=weight; PLOT / SUMVAR=height;
When
you specify a response variable, the only statistics available are
SUM or MEAN. SUM is the default. To change the statistic, you specify
the TYPE= option. For example, TYPE=MEAN.
If you do not specify
a response variable, a summary statistic for the chart variable is
computed. By default it is FREQ (frequency). You can use the TYPE=
option to indicate another statistic: PERCENT, CFREQ (cumulative frequency)
or CPERCENT (cumulative percent).
