ERRORBAR Subcommand (GRAPH command)

ERRORBAR creates either a simple or a clustered error bar chart, depending on the variable specification on the subcommand. A simple error bar chart is defined by one numeric variable with or without a BY variable or a variable list. A clustered error bar chart is defined by one numeric variable with two BY variables or a variable list with a BY variable.

Error bar charts can display confidence intervals, standard deviations, or standard errors of the mean. To specify the statistics to be displayed, one of the following keywords is required:

CI value. Display confidence intervals for mean. You can specify a confidence level between 50 and 99.9. The default is 95.

STERROR n. Display standard errors of mean. You can specify any positive number for n. The default is 2.

STDDEV n. Display standard deviations. You can specify any positive number for n. The default is 2.
