Figure 3.9, “State of the zoom stack - Zoomed in twice” shows that a stack level is
created for each action performed. On pressing Ctrl+Right twice, the time frame
of the Chart is moved to the right by two window sizes. Using the state shown
in Figure 3.10, “State of the zoom stack - Moved two window sizes to the right”,
the differences between Back (B), Zoom Out (O) and Zoom Up (U) are explained
below.

Back (B): Pressing B in the state shown in Figure 3.10, “State of the zoom stack
- Moved two window sizes to the right” pops out one level of the stack and the
previous time frame is displayed as shown in Figure 3.11, “State of the zoom
stack - after Back (B)”.

Zoom Out: Using O in Figure 3.10, “State of the zoom stack - Moved two window
sizes to the right” lowers the magnification (doubles the width) and pushes a
new item on the stack. Zooming out using O in the state shown in Figure 3.10,
“State of the zoom stack - Moved two window sizes to the right” results in the
stack as shown below.

Zoom Up (U): The resultant zoom after using U is a little more complicated.
Pressing U keeps the current center and uses the magnification from before the
