PROC CHART prints one
page per chart. Along the vertical axis, PROC CHART describes the
chart frequency, the cumulative frequency, the chart percentage, the
cumulative percentage, the sum, or the mean. At the bottom of each
bar, PROC CHART prints a value according to the value of the TYPE=
option, if specified. For character variables or discrete numeric
variables, this value is the actual value represented by the bar.
For continuous numeric variables, the value gives the midpoint of
the interval represented by the bar.
PROC CHART can automatically
scale the vertical axis, determine the bar width, and choose spacing
between the bars. However, by using options, you can choose bar intervals
and the number of bars, include missing values in the chart, produce
side-by-side charts, and subdivide the bars. If the number of characters
per line (LINESIZE=) is not sufficient to display all vertical bars,
then PROC CHART produces a horizontal bar chart instead.
