SPLIT Subcommand (TSPLOT command)

SPLIT specifies how to plot data that have been divided into subgroups by a SPLIT FILE command. The default is UNIFORM.

UNIFORM. Scale uniformly. The vertical axis is scaled according to the values of the entire dataset.

SCALE. Scale individually. The vertical axis is scaled according to the values of each individual subgroup.

• 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.

Example

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

• In this example, the data have been split into subgroups by REGION. The plots produced with the SCALE subcommand have vertical axes that are individually scaled according to the values of each particular region.
