The following statements use the PLOT procedure in Base SAS to plot CPI in the USCPI data set against DATE. (The data set plotted contains more observations than shown in the previous examples.) The plotting character used is a plus sign (+).
title "Plot of USCPI Data";
proc plot data=uscpi;
plot cpi * date = '+' / vaxis= 129 to 137 by 1;

The plot is shown in Figure 3.13.
