Example 1

The following sequence of commands draws a graph of 20*X versus 10*X and overlays a graph of (X^3)/10 versus X^2 on the same set of axes. To see the complete drawing, the REPLOT command is used.

 X=[1:20]                   ! create some data
 WINDOW 5                   ! choose graphics window
 SET PCHAR -1               ! set plotting symbol
 GRAPH 20*X 10*X            ! plot 10*X vs 20*X with axes
 SET PCHAR -2               ! choose different plotting symbol
 GRAPH\OVERLAY X^2 (X^3)/10 ! overlay (X^3)/10 vs X^2 on same axes
 CLEAR\-REPLOT              ! clear graphics but not replot buffers
 REPLOT                     ! replot all data on common scale
