Overview: PLOT Procedure
The PLOT procedure plots the values of two variables for each observation in an
input SAS data set. The coordinates of each point on the plot correspond to the two
variables’ values in one or more observations of the input data set.
Output 33.1 is a simple plot of the high values of the Dow Jones Industrial Average
(DJIA) between 1954 and 1994. PROC PLOT determines the plotting symbol and the
scales for the axes. These are the statements that produce the output:
options nodate pageno=1 linesize=64
pagesize=25;
proc plot data=djia;
plot high*year;
title ’High Values of the Dow Jones’;
title2 ’Industrial Average’;
title3 ’from 1954 to 1994’;
run;
Output 33.1

You can also overlay two plots, as shown in Output 33.2. One plot shows the high
values of the DJIA; the other plot shows the low values. The plot also shows that you
can specify plotting symbols and put a box around a plot. The statements that produce
Output 33.2 are shown in Example 3 on page 650.
