The plot shows the last 36 coordinates after iterations of the Hénon map using the initial point .

To obtain an interesting region of periodic and chaotic behavior, we use values between 0.91 and 1.41 with . Changing these values will give very similar results.

Using the lowest values for and will let you quickly find an appropriate region to inspect. Larger values will show a cleaner, more detailed plot.

The idea for the Locator-magnifier was taken from Ed Pegg Jr.
