PLOT Subcommand<br />

NONE No output other than the SUMMARY table.<br />

CORRESPONDENCE 287<br />

DEFAULT TABLE, RPOINTS, CPOINTS, and the SUMMARY tables. These statistics<br />

are displayed if you omit the PRINT subcommand.<br />

Use PLOT to produce plots of the row scores, column scores, row and column scores, transformations<br />

of the row scores, and transformations of the column scores. If PLOT is not<br />

specified or is specified without keywords, a biplot is produced.<br />

The following keywords are available:<br />

TRROWS(n) Line chart of transformations of the row category values into row<br />

scores.<br />

TRCOLUMNS(n) Line chart of transformations of the column category values into<br />

column scores.<br />

RPOINTS(n) Scatterplot matrix of row scores.<br />

CPOINTS(n) Scatterplot matrix of column scores.<br />

BIPLOT(n) Biplot matrix of the row and column scores. This is the default plot.<br />

This plot is not available when NORMALIZATION=PRINCIPAL. From<br />

the Chart Editor, you can create a two-dimensional biplot of any<br />

pair of dimensions in the biplot matrix. You can also create a threedimensional<br />

biplot of any three dimensions in the biplot matrix.<br />

NONE No plots.<br />

• All keywords can be followed by an integer value in parentheses to indicate how many<br />

characters of the value label are to be used in the plot. The value can range from 0 to 20.<br />

Spaces between words count as characters. A value of 0 corresponds to using the values<br />

instead of the value labels.<br />

• If a label is missing for a value, the actual value is used. However, the length of the value<br />

is truncated in accordance with the length parameter. For example, a category coded as<br />

100 with no value label appears as 10 if the length parameter is 2.<br />

• TRROWS and TRCOLUMNS produce line charts. RPOINTS and CPOINTS produce scatterplot<br />

matrices. BIPLOT produces a biplot matrix. For line charts, the value labels are used<br />

to label the category axis. For scatterplot matrices and biplot matrices, the value labels are<br />

used to label the points in the plot.<br />

In addition to the plot keywords, the following can be specified:<br />

NDIM Dimensions to be plotted. NDIM is followed by a pair of values in parentheses. If<br />

NDIM is not specified, NDIM(1,2) is assumed.<br />

• The first value must be any integer from 1 to the number of dimensions minus 1.
