Power and Phase Graphs

• If the user moves the mouse to the very bottom of the Power graph, and the cursor changes, then left-clicking will allow dragging the bottom of the graph upward exposing the phase graph. If the user resize the application, the phase graph will disappear and the user will have to uncover it again.
• Looking at frequency and phase coordinates can be done the same way the user can view frequency and amplitude in the power graph.
• Zooming can also be done with the phase graph. If either the phase graph or frequency graph are zoomed, the other graph will zoom in on the same frequency region that was selected for the zoomed graph.
