The first thing to do after starting dstool is to open a view
window. Open the view menu on the command window and
using ,
choose the 2-D Image entry. A window
with a title such as dstool:Lorenz System
(figure
) appears. It may well obstruct
some other important window - using
on the header, drag the
window to a convenient location. The view window
contains abbreviated menu buttons for selecting the horizontal and
vertical coordinates being displayed, as well as text fields
controlling the coordinate ranges of the viewport. ( These coordinate
ranges are expressed in the original world coordinates of the
dynamical system. ) Coordinates displayed in view windows can be
phase space coordinates of the original problem, auxiliary functions,
or parameters built into the dynamical system at creation.
For the Lorenz system, the default display is to project the
phase space coordinates (x,y,z) to (x,y) as horizontal and
vertical coordinates of the view window.
Move the mouse within the canvas below the view window control panel. The canvas is the large boxed-in area where graphics are displayed. Note that the horizontal and vertical coordinates of the mouse position (in world coordinates) appear to the right of the options menu button.
Within the limits of system resources, you can open as many view windows as you like. So it's possible to view a number of two dimensional projections simultaneously. BY default, the same orbit in different windows will be drawn in the same color. Different orbits will generally be drawn in different colors. The use of color is controllable as described in Section 1.2.17.
