FORMAT Subcommand (CASEPLOT command)
FORMAT
controls
the plot format.
- The specification on
FORMAT
is one of the keywords listed below. - The keywords
NOFILL
,LEFT
,NOREFERENCE
, andREFERENCE
apply to plots with one variable.NOFILL
andLEFT
are alternatives and indicate how the plot is filled.NOREFERENCE
andREFERENCE
are alternatives and specify whether a reference line is displayed. One keyword from each set can be specified.NOFILL
andNOREFERENCE
are the defaults. - The keywords
JOIN
,NOJOIN
, andHILO
apply to plots with multiple variables and are alternatives.NOJOIN
is the default. Only one keyword can be specified on aFORMAT
subcommand for plots with two variables.
The following formats are available for plots of one variable:
NOFILL. Plot only
the values for the variable with no fill. NOFILL
produces a plot with no fill to the
left or right of the plotted values. This is the default format when
one variable is specified.
LEFT. Plot the values
for the variable and fill in the area to the left. If
the plotted variable has missing or negative values, the keyword LEFT
is ignored and the default NOFILL
is used instead.

NOREFERENCE. Do not plot a reference line. This is the default when one variable is specified.
REFERENCE(value) . Plot a reference line at the specified value or at the variable mean if no value is specified. A fill chart is displayed as an area chart with a reference line and a non-fill chart is displayed as a line chart with a reference line.

The following formats are available for plots of multiple variables:
NOJOIN. Plot the values of each variable named. Different colors or line patterns are used for multiple variables. Multiple occurrences of the same value for a single observation are plotted using a dollar sign ($). This is the default format for plots of multiple variables.
JOIN. Plot the values
of each variable and join the values for each case. Values
are plotted as described for NOJOIN,
and the values for each case are joined together by a line.
HILO. Plot the highest
and lowest values across variables for each case and join the two
values together. The high and low values are plotted as
a pair of vertical bars and are joined with a dashed line. HILO
is ignored if more than three variables
are specified, and the default NOJOIN
is used instead.
