Window title:
DsTool: 1-D View #n
Function:
The 1-D View window graphically displays computed data.
Description:
The 1-D View window is opened by selecting the 1-D View option from the Panels menu button located in the Command window. The 1-D View window can only be opened when the current dynamical system is a one-dimensional mapping, $f: {\mbox{\Bbb R}} \to {\mbox{\Bbb R}} $. Multiple 1-D View windows can be open simultaneously. All 1-D View windows display the same data, but they may use different scalings.

The window displays the ``cobweb diagram'' for trajectories of the system. That is, given an initial point $x_0$, we draw a vertical line from $(x_0, 0)$ to $(x_0, f(x_0))$, and then a horizontal line to $(f(x_0), f(x_0))$. We then repeat the process starting for $x_1 = f(x_0)$ drawing lines from $(x_1,x_1)$ to $(x_1,f(x_1))$ to $(f(x_1),f(x_1))$, and so forth.

When the window is open, data is displayed as it is computed. When the user resizes the window, the current variable ranges are maintained, but the scaling is adjusted accordingly.

As the user moves the mouse in the drawing canvas, the current coordinates of the mouse position are displayed in the window's panel. This region is blank when the mouse does not point into the canvas. Mouse events in the main drawing canvas have the following effects:
