PLOT Subcommand (FACTOR command)

Use PLOT to request scree plots or plots of variables in rotated factor space.

• If PLOT is omitted, no plots are produced. If PLOT is used without specifications, it is ignored.
• If more than one PLOT subcommand is specified, only the last one is in effect.
• If any ANALYSIS subcommand is explicitly specified, all PLOT subcommands specified before the last ANALYSIS subcommand are ignored. If no PLOT subcommand is specified after the last ANALYSIS subcommand, no plot is produced.

EIGEN. Scree plot ¹. The eigenvalues from each extraction are plotted in descending order.

ROTATION. Plots of variables in factor space. When used without any additional specifications, ROTATION can produce only high-resolution graphics. If three or more factors are extracted, a 3-D plot is produced with the factor space defined by the first three factors. You can request two-dimensional plots by specifying pairs of factor numbers in parentheses; for example, PLOT ROTATION(1,2)(1,3)(2,3) requests three plots, each defined by two factors. The ROTATION subcommand must be explicitly specified when you enter the keyword ROTATION on the PLOT subcommand.
