• X2 adds a third dimension, corresponding to division, to the boxplot in the previous
example.
• COORDINATE indicates that the chart displays the third dimension.
• BOX creates a boxplot without outliers or a median line. Extreme values are shown.
• LABEL labels each box with the number of cases represented by each box.
• BOXBASE defines the three-dimensional representation of the boxes to be cylindrical.
LINE Subcommand
LINE creates line charts, dot charts, and ribbon charts. These charts summarize categories of
one or more variables. Line charts tend to emphasize flow or movement instead of individual
values. They are commonly used to display data over time and therefore can be used to give
a good sense of trends. A ribbon chart is similar to a line chart, with the lines displayed as
ribbons in a third dimension. Ribbon charts can either have two dimensions displayed with
a 3-D effect, or they can have three dimensions.
The following keywords are available:
summary function Defines a function used to summarize the variable defined on the Y
subcommand. If the Y axis assignment is $COUNT or $PCT, the LINE
subcommand cannot have a summary function. If the Y subcommand
specifies TYPE=CATEGORICAL, then LINE can specify only MODE as
the summary function. Otherwise, all summary functions described on
p. 764 are available.
STYLE Chart can include dots and lines (DOTLINE), lines only (LINE), or dots
only (DOT). The keyword NONE creates an empty chart.
DROPLINE Indicates whether drop lines between points having the same value of
a variable are included in the chart (ON) or not (OFF). To include drop
lines, specify a categorical variable on the STYLE, COLOR, or SIZE
subcommands.
LABEL Labels points with the actual values corresponding to the dependent
axis (VAL), the percentage of cases (PCT), and the number of cases
included in each data point (N). The default is no labels.
LINELABEL Labels lines with category labels (CAT), the percentage of cases
(PCT), and the number of cases included in each line (N). The default
is no labels.
BREAK Indicates whether the lines break at missing values (MISSING) or not
(NONE).
