Changing Graph views:
1.) To rotate the graph use the up, down, left and right arrow keys on your
keyboard.
2.) To zoom in press "page up." To zoom out press "page down."
3.) To return the graph to the original position that it started, press "home."
4.) To change the color, background, or have the graph continuously rotate,
click on "color," "background" or "animate" in the upper tool bar while the
kinetic graph is displayed.
Changing Physical Parameters:
When the kinetic graph is displayed, you can change the physical parameters of the wave by clicking on "scroll bar" in the upper tool bar. In that menu, you will find that you can click on bubbles next to "a," "b," "c," or "d." These represent physical parameters of the wave. When you click on any of these and the press "execute" at the bottom of the menu, you will then find a vertical scroll bar on the right side of the screen. This scroll bar will allow you to vary the physical parameter of the wave.
The following parameters can be varied in the scroll bar menu:
1.) The angular frequency can be can be changed by selecting "d."
2.) The propagation number (k=2p / l) can be can be changed by selecting "c."
3.) The reflection coefficient can be can be changed by selecting "b." (It varies from -1 to 1.)
4.) The damping factor (alpha) can be changed by selecting "a" in the scroll bar menu. (It varies from 0 to 0.15 .)
Suggestion: Print these instructions out or reduce the DP Graph Viewer window to make these instructions visible. This will allow you to use the instructions while viewing the kinetic display more easily.
** Note: The menu under "edit" displays the equations and programming used to produce the kinetic graph. DP Graph Viewer will not allow you to change this programming and press "execute." The actual DP Grapher software is necessary for this.
