In Figure 4, we present a picture of the Hénon attractor for a fairly large number of points (). If one could increase the number of points by one or two orders of magnitude, the self-similarity inherent in the attractor would manifest itself, as we show in Figure 5.

Figure 4 **x**--**y** plot of the Hénon attractor.
The diagram was created
by first executing a fortran program with
initial values and ; 10,000 iterations were performed and
the calculated points
plotted with xmgr.

Figure 5 Pictures illustrating self similarity for the Hénon attractor. The diagram was created by first executing a fortran program with initial values and ; 50,000 iterations were performed and the calculated points plotted with xmgr. The xmgr ``magnifying glass'' was used successively to zoom in on the regions indicated by the rectangles.
