ERRORBAR Subcommand (XGRAPH command)
The ERRORBAR
subcommand adds errors bars to the chart. Error bars indicate the
variability of the summary statistic being displayed. The length of
the error bar on either side of the summary statistic represents a
confidence interval or a specified number of standard errors or standard
deviations. Currently, XGRAPH
supports error bars for COUNT
and population pyramids.
The keywords are not followed by an equals sign (=). They are followed by a value in parentheses.
Example
XGRAPH CHART=([COUNT] [BAR]) BY agecat[c] BY gender[c]
/COORDINATE SPLIT=YES
/ERRORBAR CI(95).
