In this example, the PLOT statement uses a plot request of the type y-variable*x-variable to plot the variable HIGH against the variable YEAR to show the annual highs of the Dow Jones Industrial Average over several decades.

This example uses a SYMBOL statement to specify a plot symbol and connect data points with a straight line. In addition, the example shows how PLOT statement options can add reference lines and modify the axes (AXIS statements are not used).
