SPLIT Subcommand (CASEPLOT command)

SPLIT specifies how to plot data that have been divided into subgroups by a SPLIT FILE command. The specification on SPLIT is either SCALE or UNIFORM.

• If FORMAT=REFERENCE is specified when SPLIT=SCALE, the reference line is placed at the mean of the subgroup. If FORMAT=REFERENCE is specified when SPLIT=UNIFORM, the reference line is placed at the overall mean.

UNIFORM. Uniform scale. The horizontal axis is scaled according to the values of the entire dataset. This is the default if SPLIT is not specified.

SCALE. Individual scale. The horizontal axis is scaled according to the values of each individual subgroup.

Example

SPLIT FILE BY REGION.
CASEPLOT VARIABLES = TICKETS / SPLIT=SCALE.

• This example produces one plot for each REGION subgroup.
• The horizontal axis for each plot is scaled according to the values of TICKETS for each particular region.
