Orbits of Martin's Map

This is the two-dimensional map known as Martin's map: , .
Orbits are generated by iterating the map times using different initial points. The map parameters , , and can be varied manually or a random set can be launched. Three orbits are plotted initially, starting from three different initial points marked by locator objects "". You can drag these initial points or add and/or delete new ones (Alt+Click on Windows) inside the plot. Three orbit colors are used cyclically.

All locator objects can be hidden for a "cleaner" plot. The plot range can be changed to full to include all points from all orbits.
The Martin map equations were taken from:

The Martin Map is also called the "Hopalong-Attractor".
