Changing the Plane of Projection

Those familiar with the Lorenz system may have noticed that the orbits which appear here do not look like the phase portrait normally associated with the Lorenz attractor. This is because dstool is projecting this three dimensional system onto the xy-plane. To change the plane of projection, locate the abbreviated menu button labeled Ver: on the view window control panel. Open this menu and select the variable z to replace y as the vertical coordinate. Then open the Options menu button just below and select the Refresh menu entry. The screen will redraw each orbit as projected into the xz-plane. (See figure [*]).

In the same way as above, values of auxiliary user-defined functions can also be displayed in 2-D Image windows. Or time may be chosen as one of the displayed coordinates to generate time series. The Dstool Users Manual explains how to add user-defined functions to a particular dstool system.
