SPSS® 12.0 Command Syntax Reference

756 IGRAPH
• Y assigns the built-in dimension $count to the range axis.
• VERTICAL defines the counts to appear along the vertical dimension.
• BAR adds a bar element to the chart.
• LABEL labels the bars in the chart with the number of cases included in the bars. These
labels appear inside the bars.
• SHAPE indicates that the bars are rectangles. However, EFFECT adds a third dimension
to the chart, yielding three-dimensional solids.
Example
IGRAPH
/X1=VAR(volume94) TYPE=CATEGORICAL
/Y=VAR(sales96) TYPE=SCALE
/COORDINATE=HORIZONTAL
/EFFECT=NONE
/BAR (MEAN) LABEL OUTSIDE VAL SHAPE=PYRAMID BASELINE=370.00.
• X1 assigns the categorical variable volume94 to the X1 axis.
• Y assigns the scale variable sales96 to the range axis.
• HORIZONTAL defines sales96 to appear along the horizontal dimension.
• EFFECT defines the chart as two-dimensional.
• BAR adds a bar element to the chart.
• MEAN defines the summary function to apply to sales96. Each bar represents the mean
sales96 value for the corresponding category of volume94.
• LABEL labels the bars in the chart with the mean sales96 value. These labels appear
outside the bars.
• SHAPE indicates that the bars are pyramids.
• BASELINE indicates that bars should extend from 370. Any bar with a mean value above
370 extends to the right. Any bar with a mean value below 370 extends to the left.
PIE Subcommand
A simple pie chart summarizes categories defined by a single variable or by a group of related
variables. A clustered pie chart contains a cluster of simple pies, all of which are stacked into
categories by the same variable. The pies are of different sizes and appear to be stacked on top
of one another. The cluster contains as many pies as there are categories in the cluster variable.
For both simple and clustered pie charts, the size of each slice represents the count, the percentage,
or a summary function of a variable.
The following keywords are available:
summary function Defines a function used to summarize the variable defined on the
SUMMARYVAR subcommand. If the SUMMARYVAR assignment is
$COUNT or $PCT, the PIE subcommand cannot have a summary function.
Otherwise, of the summary functions described on p. 764, SUM,
SUMAV, SUMSQ, NGT(x), NLE(x), NEQ(x), NGE(x), NGT(x), and
NIN(x1,x2) are available.
