specifies the variables for which PROC CHART produces a
pie chart, one chart for each variable.
The options available on the BLOCK, HBAR, PIE, STAR, and VBAR statements
are documented in Customizing All Types of Charts.
PROC CHART determines the number of slices for the pie in the same way
that it determines the number of bars for vertical bar charts. Any slices
of the pie accounting for less than three print positions are grouped together
into an "OTHER" category.
The pie's size is determined only by the SAS system options LINESIZE=
and PAGESIZE=. By default, the pie looks elliptical if your printer does not
print 6 lines per inch and 10 columns per inch. To make a circular pie chart
on a printer that does not print 6 lines and 10 columns per inch, use the
LPI= option on the PROC CHART statement. See the description of LPI= for the
formula that gives you the proper LPI= value for your printer.
If you try to create a PIE chart for a variable with more than 50 levels,
then PROC CHART produces a horizontal bar chart instead.
