The H
non map is drawn continuously, but the display is only updated between orbits. This means that the computer appears to be inactive for long periods of time if you're plotting many points per orbit. What it's actually doing, though, is plotting the points into an offscreen bitmap. The bitmap gets composited to the screen at the end of every orbit.\
Values typed into the fields on the right side of the main window won't take effect immediately
they only apply to new plots. If you're already plotting a map, stop it first by clicking the Stop button.\
The number of the orbit that's currently being plotted is displayed in a text field on the right. This box is for information only; you can't edit the orbit number. You can, however, immediately skip to the next orbit by clicking the button labeled
Next Orbit
The
Interesting Maps
menu contains the plot para- meters for some interesting H
non plots. Selecting a menu item in this menu will replace the current parameters in the right hand side of the window with sample ones. You can the click on the Plot button to start plotting using the new values.\
The mysterious-looking box labeled
Window onto real # plane
may need some explanation. The black box represents a window onto the plane of real numbers. This is the plane the H
non map is plotted on, and it is always centered at the origin. The word
\i window
\i0 shouldn't be confused with a NeXT window
here the word refers to the two-dimensional range of the plot.\
The text fields next to the edges allow you to change the limits of this virtual window. The box by each each edge represents the coordinate of that boundary. For example, the white box below the lower horizontal line of the black box represents the lower
\i0 coordinate.
